Ok done another test, the frame rates at WFHD & 4xFSAA average 41fps, min 12.6 (give or take .2fps) next test i did was at 640x480 & No FSAA and got 98fps with a min of 10.4fps Tell me how come when running at a significantly lower resolution did my minimum frame rates drop by 20%!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I tell you why cause the GPU bottleneck has been completely removed and pushed onto the CPU which in turn is more taxing when it has to calculate psychics on top that's why there is a big drop! Now nvidia physx can run in software (CPU with any GPU) or hardware mode (GPU only on nVidia GPU) Look in the game directory and you can see the nvidia physx files right here. Interesting looking at them, that nVidia GPU's gain a massive increase when FSAA has been turned off in some cases 50%, and AMD's gets next to zero increase in min fps. Think that completely answers my Question. I have been real time monitoring it and the frame rates drops with the water effects, CPU usage maxes out on all cores.
