well i don't know any programs to run fps that's why i used the fps thing on the hack it was saying 18-20 and i wasn't lagging at all when 8 seconds later my fps drops to 9 or below result in a lag spike. (But Note that this only happens when i set CA engine.exe priority to low) if i don't set it to low its no lag spikes but i crash. I was stetting engine.exe priority to low for a while now to stop the crashing from last year idk why its spiking my fps when i do it now.
im running:
Windows7 ultimate
64 bit
RAM-3GB
Graphics ATI radeon 3200
