I am having the same problem as our friend here. I should note that the problem started after switching to Win2k. WinXP ran war3 fine, but since fresh win2k install I get choppy screens and lag (Note: single player only, I dont do Bnet). Specs, for the spec monkeys, are as follows: PIII 866, 512 ram, big hard drive, Win2k fresh install (i.e. no service packs), SBlive sound card (which War3 will not recognize, defaults to emulated) and a Geforce 2 Pro Vidcard with latest (29.42) drivers.
I guess my question is this... Are there any issues with Win2k? I have scoured the forums and cannot find a single Win2k issue section or really any OS related problems. I would hate to have to go back to XP because its networking is horribly slow, when it doesnt just freeze up my PC.
Any info is appreciated, even smart ass remarks.
