Win 7 Cpu affinity gaming.

post #1 of 4
Thread Starter 
For a while now ive been doing the CPU affinity trick to some games, i do this because those games seem to max out Cpu core #1 and bottleneck the GPU.

this is what the "trick" is:

Set Cpu affinity to anything but all 4 cores, click ok, and now set cpu affinity back to all 4 cores.

this seems to make the game spread the CPU usage across all 4 cores, almost like multi-threading.

anyone have any idea whats happening with this trick? its not just a visual trick, it actually helps performance a decent amount on very speicifc games (like rome 2)

PS: not sure if this thread belongs in video games, CPU's or windows forum.

I think that nvidia's "threaded optimization" does this already, but i'm not sure..
