Nvidia and FPS question

[leviathon6425]

I was messing about with my nvidia controld panel and i added pcsx2 for application control. The 2 settings which i enabled were threaded optimization and sli optimization. I dont know know if this causes problems or not but my FPS have been more stable when playing heavier games, i dunno maybe its my wishful thinking but i would like to know if anybody tried this before?

Second why does 30 fps is so noticeably slow? Some modern HD games for 360/PS3 are set to 30 fps and are playable just fine. Just curious.

It's wishful thinking.
For PS2 games, 50 FPS is full speed for PAL and 60 FPS for NTSC games, it has nothing to do with FPS in PC games
