Slowing down the simulation speed in proteus?

[ChemroukO]

Hello everyone,

I am currently using Proteus 8.4 & I liked it a lot. But, sometimes it fails to run the simulation properly (Exceeding Cpu) & it starts to lag.

Can't I reduce the simulation speed (from real-time x1 to something like x0.5) as what can be done in NI multisim

Thanks a lot.
