I saw some help for y'all over on the aa.net boards, try leaving it at the same resolution, but turning textures down to medium, instead of high. Apparently to make the demo smaller they didn't include the high quality compressed textures, so the textures you're seeing require the game to do a lot more processing than it should. It helped me, and I'm running a P3 1 Gig, GeForce 3 Ti 500, 256 MB SDRAM. It was stuttering by the gun, and every now and then throughout. Especially when the Tiger Tank blew up the wall....cool effect, but it KILLED my framerate. So here's hoping that helps some of you, btw, that new sound pack works in SP, and it's AWESOME.
