Requires Windows 8, 7, Vista, or XP SP3
try upgrading your computer that will help when more particles are on screen maybe a better graphics card that can process more particles and a better processor to help with the math for the physics part
or if any 1 knows if the ageia physics cards make any dif with US??
It's probably rather a problem of the mainboard which has to calculate all the positions and velocities of the particles. Anyways, I think there are already quite a lot of cheap multicores out.
will it also support quad core as well or will it only use 2 of the 4??
