By taking a PC, and using diagnostics, investigating things like Windows event logs (errors), benchmarks, various internal processes, computer stress tests, memory checkers, etc etc. You should be able to find out specific error messages and/or failures detected. Which can then be used to help determine what is really going wrong with these PCs. Regardless of if the real problem is your PCs, their hardware/software, internet connections, mains supply, humidity level, rf/emi, etc etc.
Hence me wanting to narrow in to what the real problem(s)/issues are.

Usually when you have problems like you describe, there are error logs, and other sources of information. Which can give valuable clues as to what is wrong.

In the investigations so far, have you ever been able to get any specific error codes, warnings, test failures etc, giving clues as to what the issues might be ?

You didn't seem to mention an earlier PC, in the thread, originally. What is the story behind the earlier/original PC. What went wrong with it exactly (symptoms etc) ?

For last 3 years I've never detected any problem during benchmarks, stress tests, memory tests etc. Temperatures were always good and I know how to take care about PC. I can repeat them one more time, but believe me I am already tired of this. However I am curious about tracking UDP packets but I don't have enough skills to do that.

Regarding my first PC in short. I knew that something was wrong, because I bought PC few days after I visited gaming cafe where I played CS:GO. Clicks were processed way too slow. I couldn't make crisp peeks behind corners. Also 144Hz smoothness was really crappy and monitor was the first thing I replaced to new 240Hz BenQ XL2546 (number 1 monitor on market that time) and again I felt that something is wrong. I could see intense ghosting after few weeks, any motion was leaving kind of trace so I RMA it. BenQ has DyAc technology which in theory should smoothen everything to the limit but I couldn't see the difference. After that I was becoming more paranoid and more. Everyday changing settings, replacing every part, internet providers and by that I ended up on electricity because I had no more ideas. Then I found a group of people fighting with same issue, some of them claimed that big ferrite toroids helped, some of them made chemical ground, another just changed location and forgot about this nonsense.

By taking a PC, and using diagnostics, investigating things like Windows event logs (errors), benchmarks, various internal processes, computer stress tests, memory checkers, etc etc.

There is no actual raw performance problem though, as reported by OP. They are claiming benchmark is always good.


Frame times graph is ok, I had spikes before caused by some RGB software but currently everything is fine except slow/sluggish inputs and no 240Hz feeling. If I had to compare this to something, just imagine playing on cheap 24'' gaming laptop. CS:GO, when working good, has really crisp and precise movement and hits are registering normal but motion on my PC looks like walking with lead shoes. The game is simply slower than is should be.

Then its something like this: https://www.pcgamer.com/what-is-microstutter-and-how-do-i-fix-it/

If it was actually an issue related to EMI/power/humidity/etc, how would you not see problems in the frame time? Or in benchmark results that heavily stresses the CPU and RAM?

Frame time "quality" issues are generally correlated with drivers/driver settings (ie. MSI Utility)/softwares/throttling. I believe that integrated circuits/capacitors/conductors in the monitor are somehow affected but can't be detected by software. I don't know to what I can compare it, but imagine strong magnet touching CRT monitor. You gonna see artifacts. Can you detect it from software level?

Going back a step or so. I remember you saying something like a fresh install, of just the absolute bare bones software on your PC, worked for around 1 day, before issues started. If that is the case, then it could be that either you are (at a later time) installing one or more, problematic pieces of software. Which is causing these issues, or your windows system is damaging the windows installation itself (probably much less likely, EDIT: On the other hand, windows could be changing the drivers/settings/stuff, after a day, with its automatic updates and stuff, so maybe ?).

Are you saying that if you do a bare bones installation, and install nothing else. Then after a day of gameplay, it starts to re-show these issues you have been experiencing ?

This question is important. Because if it is electricity supply, humidity, rf/emi, hardware, etc. Then it probably shouldn't work well for one day, after a bare-bones installation. Since those problems would more than likely, immediately stop it from working properly. I.e. The one day delay before your problem shows up, doesn't make a lot of sense, unless it is some software being installed after the one day is up.

I didn't just mean performance benchmarking. I also meant, checking signs of frames taking longer to be produced than they should. I.e. fps minimum and/or unexpected sudden drops in fps, which would tie in with the problems the OP has been having. Maybe.

I had nothing except latest nVidia driver, Steam and Counter Strike. Nothing else. For one day it was acceptable but not perfect. To clarify, it was not about smoothness of my display (which on random days around 4-5 AM becomes really smooth like never before, it happens pretty seldom) but only inputs and desync. If you start digging in the Internet, lots of people claims that after format it is fine for some time and the issue is coming back. Nonsense.

I assume you checked the ping times in your game.
https://win.gg/news/heres-how-to-show-fps-ping-packet-loss-and-more-in-csgo/#:~:text=The%20option%20is%20a%20tickbox,the%20corner%20of%20your%20screen.

Because your internet connection, could be improving at around 4:00AM to 5:00AM, as so few people use the internet at that sort of time. Potentially improving things like ping rates and stuff.

Although you said earlier, you had tried changing ISP. I would suspect the basic infrastructure/equipment they use, is shared, at least near your end, between different ISP companies (I don't know for sure, in your country). So, although you changed ISPs, it may not have changed the nearby equipment you were really using, at the telephone exchange, phone/internet lines/equipment, outside of where you live, until it reaches the actual ISP.

A bit late to the party, but my 0.02 Euro:

The humidity should impose no big problem. We see here something between 60%-80%, which is fine unless it is able to do some condensing on some part where it affects performance (like fans etc.)

Humidity is critical when below 20% RH, because of the building of static charges and unloading. At my last employer (Datacenter/Webhoster) we had humidifiers in the main cooling cabinets to make up for that stuff in winter.

Other shot in the blue: What about the thermal paste between CPU and Heatsink? If this connection is not great, or you have assembly problems there, you also could get heat issues that result in throttling.

I didn't experience heat issues in RDR2 @ ultra settings nor in csgo

Can you give us the entire parts list for your PC? Could be CPU bottleneck or something else we can't tell if we don't know that. Unless I missed it I didn't see the full parts listed.

Also I agree that you need to run 3DMark and post the results you get here. It's a benchmarking software you can get on Steam.

Also, what FPS are you getting in which games?

Nice specs. Okay, so it looks like decent performance, should still run 3D Mark or some other benchmarking software if you can.

What monitor are you hooked up to?
Is the monitor cable plugged into the graphics card or the mother board?

Acer Predator, monitor cable is plugged into GPU because I don't have integrated graphic card. Benchmark will indicate nothing, you can't measure input lag with software, you can't measure real smoothness of your monitor. You need high speed camera for that and little bit of electronic skills.

I asked for frame time graphing and they already claim to have done that.

Not happening.
You already said you've tried multiple monitors, so any monitor related EMI/ESD issue is ruled out. EMI would never cause ghosting anyway.

Of course that monitor model itself may be bad, but, just borrow someones monitor or take your PC to a friends house, etc.

I am not sure if you know what ghosting is.

Frame time is good. I've checked it multiple times with MSI Afterburner.

In some cases ghosting can easily be induced in the settings menu of the monitor:

Quote
The Acer XB253QGP has three pixel response time overdrive modes (Off, Normal, and Extreme).
Since the Extreme mode is too aggressive and adds too much pixel overshoot (inverse ghosting), we highly recommend sticking with the Normal mode.

I appreciate your willingness to help, but I would like read ideas about possible EMI/RFI or other electrical issues.

Its nothing to do with EMI.
You have yet to take the machine to a friends house and run it there, as was suggested above.

One of my buddy claims that it's fixed after disconnecting old FM/AM radio.

So somehow a radio, which is very low power, emits enough EMI to cause minor, but not major, problems to a device housed in a shielded metal box? (well some have windows on the side...)
And somehow this same issue is affecting you in a similar same way, and cannot be measured, its only based on "feel".

Looks like there are forums dedicated to this BS idea: https://forums.blurbusters.com/viewforum.php?f=24
At least they have some self awareness: https://forums.blurbusters.com/viewtopic.php?f=24&t=9562

And you assume that it's not EMI basing on what? I can ask him to come here and he will explain how he managed to fix it. You can trust me or not I don't really mind. It's based on my "feel" having tens of thousands hours in games and compared to what I experienced in the past.

I would like read ideas about possible EMI/RFI or other electrical issues.
The problem is that EMI/RFI does not cause such minor effects at all.

I know this sounds hostile and unreasonable to you, but here's the thing: we know how these devices work, intimately.  What you are describing is like claiming that you can feel the color of the surface you're walking on: not the material or paint type used, but the color itself.   If you are human, you do not have cone cells in the soles of your feet actually connected to your central nervous system.  It is therefore almost certain that if you really believed it to be so, it was a correlation: instead of sensing the actual color, your senses had managed to collect correlated information, letting your human mind connect the correlation to causation.  Which is very typical of us humans.

Electromagnetic interference and radio frequency interference can affect a computer, sure.  However, the way computers are constructed means that either such effects are corrected without any overhead (as in ECC memory, reading data off an SSD or HDD or a CD/DVD/BluRay disc), the error is ignored/overlooked (say, changing just one bit that does not affect the result enough for noticeable effects), or the computer crashes or locks up due to the error.

The processors do not "redo" work when it notices an error.  Except for network communications, error correction is done in hardware (and the hardware does whatever it does in the same time regardless of whether there were errors corrected or not).  In network communications, the information sent and received is in packets, with each packet containing a checksum.  If that checksum mismatches, the packet is thrown away, and the sender has to re-send it.

As an example, consider ECC RAM.  It works at a specific rate, each read and write access taking a specific amount of time.  This time is listed on the chips or the memory module.  The motherboard contains hardware that during each access, verifies the contents match the extra error correction bits; and if not, "fixes" the data.  (This is the difference between checksums and error correction codes: the former are designed to indicate integrity, the latter are designed to be useful to fix integrity issues.)  If the data cannot be fixed, a Machine Check Exception occurs, and in past Windows versions, this causes a bluescreen.  In no case is there a measurable slowdown regardless of whether an error occurred, a correction was attempted, or not: the ECC works at the same rate in all situations.

(Perhaps CDs would have been a better example, because they often have errors –– scratches and whatnot.  If the ECC slowed the player down, then even minor scratches corrected by the player (so that no glitch is left in the audio data), the player would slow down and the corrected errors be audible!  That would make ECC useless in a CD player.  Yet, CD players were a major step forward in ECC use.  The only case you can actually hear a glitch from a CD is when the player cannot correct the errors anymore.  Because it is a simple device, it often loses its place in the spiral, and starts repeating the same thing.  Computers are more complex, and instead of stuttering like that, they just crash.)

I am still assuming there is actually something wrong in your computer setup.  The timer latencies you showed in post #21 definitely look horribly wrong.

To prove it is a "software problem" –– meaning something not electrical, but something in the OS, motherboard, interaction between motherboard and processor, EFI BIOS, or even malware or virus somehow re-infecting your machine –– I would recommend you do a fresh reinstall of your machine, and before installing any games or anything, redo the kernel timer latency test you did in post #21.  If indeed a fresh reinstall makes the problem go away for a short while, and it is a software issue related to kernel timers (because they're the one thing in this thread that could cause the issues you're seeing), you'll see the timer latencies be much, MUCH smaller.  And, if/when the issues come back, the timer latencies also grow to the huge values you showed in post #21.

I know that is quite a bit of work (or, rather, time spent for just to confirm a possible cause); but, it is the most likely actionable (as in, "this we can do something with") symptom thus far.  If indeed the kernel timer latencies correlate with the problems you observe, and do not occur in a freshly reinstalled system, we at least have a clue we can work from.  (While I personally cannot tell you how to fix that kind of an issue, I can help with how and where to report the issue to get a fix.)

They do or they don't. If you search around, you will find reports that those numbers change with system load, like running two of those tests at the same time may improve the results of one or both. It could be some power optimization as I said, and it could be enabled/disabled by OS heuristics or API calls made by applications or whatever. No one here has any idea.

The fundamental problem is that OP can't even state what exactly is wrong and nail it down with a reproducible test.

At this point I may humbly suggest quantum stickers. You put them on capacitors, they filter all the EMI/RFI/EMC crap from your electricity by means of science.

I think it is even worse than that very good summary. They seem to have enabled an automatic memory overclocking (if I understood, the earlier OP posts correctly) feature of their motherboard, but they seem to be refusing to run a memory checker (and computer stability checker) for long enough to give reliable results (e.g. overnight). Which is (overclocking), a well established way of making a computer unreliable, and fail in all sorts of weird, strange and very hard to diagnose ways.
They don't seem to have responded to my requests for windows event viewer results (which may have found errors and hence the real cause of any issues), or ping (within their favorite game) results.

Yet (Warning: Possible sarcasm and exaggeration, for dramatic effect, follows), someone in a park, half a mile from where they live, switches on an AM radio, or it rains, increasing humidity, and their 50,000+ hours of gaming experience, means they know exactly what is wrong, and can ignore all computer enthusiasts and other people trying to give them apparently sensible advice.

They seem to have enabled an automatic memory overclocking (if I understood, the earlier OP posts correctly) feature of their motherboard, but they seem to be refusing to run a memory checker (and computer stability checker) for long enough to give reliable results (e.g. overnight). Which is (overclocking), a well established way of making a computer unreliable, and fail in all sorts of weird, strange and very hard to diagnose ways.
They don't seem to have responded to my requests for windows event viewer results (which may have found errors and hence the real cause of any issues), or ping (within their favorite game) results.

Yet (Warning: Possible sarcasm and exaggeration, for dramatic effect, follows), someone in a park, half a mile from where they live, switches on an AM radio, or it rains, increasing humidity, and their 50,000+ hours of gaming experience, means they know exactly what is wrong, and can ignore all computer enthusiasts and other people trying to give them apparently sensible advice.

It's human nature.  E.g. an audiophool that just paid $5000 for a new mains cord...  he will hear a difference, for sure.  A gamer that paid $5000 for a really ace setup - is going to believe his PC is now better than anything else.   A hot rodder is going to believe his built V8 is faster than 99% of cars (even if a stock Honda Civic beats him at the traffic lights due to traction issues).  We are all affected by this syndrome to a greater or lesser extent.  E.g. test gear addiction!  :D

You are right. Sometimes I've fixed something, or replaced something, or got a new something. Then delightedly noticed that the new/repaired/improved one, is significantly smoother, nicer, a bit faster, and better quality than the old one. Later still, I discover that I was actually still using the old one, and all my perceived improvements were actually purely psychological.
I can't remember those previous experiences in enough detail, to describe here, so here is a made up example (but based on my typical experiences, when it happens).

(Hypothetically) My old torch (flashlight) seems a bit old, sometimes flickers on and off, needing a tap/bang to fix and seems dimmer than modern torches. So I get a new one, then later still try it out, and notice all the improvements, as above. But when I get back from the dark and can see the actual torch I was using, it was actually the old one, rather than the new one.

I recorded benchmark monitor under load. Maybe you will spot something suspicious because I couldn't.

Is it suppose to highlight (via a tiny, filled in red tick box) certain bits in red like that, doesn't it mean it is possibly too hot for those particular tests ? EDIT: No that bit is fine.
It seems to say around 90 deg C, for the graphics hot-spot thing, which seems to sound rather high.

But I'm not sure, it could easily be fine, or not ?

Some of the cpu temps seemed on the high side as well, but depending on what load it had at the time, and your cooling solution settings. It could be ok, I guess. Or it could be near or at the throttling point, and automatically limiting the cpu speed, to keep the cpu from becoming too hot (bad).

Some graphics cards, under some conditions, can run hot.

The solution is someone very use to that particular test suite you used (or at least well versed with the expected results), to look at it and/or more/better tests.

Don't worry too much, it is relatively normal, for results to sometimes appear bad. I'm not especially familiar with that software you used.

That's why I tried to get you to use one of the computer forums, with many computer enthusiasts, who will be well familiar with the best software test suites, expected test results, how to pursue possibly faulty results. There could be such people here, but you are more likely to find them on computer enthusiast forums (and similar), especially in their graphics and/or cpu and/or gaming computer sections.

Don't worry, it could easily be fine. Just may need looking into further.
