lol see the thing is is that it is not yet suited for all kinds of specs. What i mean is that look at my comps specs:
551 mhz P3
32mb ATI Rage Fury
256mb RAM
20 gb HD
56k dial up
These are pretty bad specs too, well at least the cpu is, but i run PS fine mos tof the time and i barely get lag.
see you almost triple me in cpu, you double me in graphics card mb, and im not sure about the last 3 but only the amount of ram really matters out of those 3. BTW how much RAM do you have? Memory is very very important! I think to run smoothly you need atleast 192 or 256mb.
Now about the settings, run in full screen mode, this way windows does not have to create a window so it doesn\'t have to take any memory, that is good. Make sure it is in opengl mode, and like 16 bit or whatever its called, not 32, heck you might even wanna try 8
