to my delight, i tried playing C&C3 sa Windows Vista and lo and behold... performance is smooth on 1024x768 High Settings and 1280x800 Medium Settings... I now think the problem lies on the ATI Radeon driver because ATI Drivers for Asus laptops are not frequently updated, worst are very ancient...
Best of all, never crashes... May problema yata DirectX ko sa XP e though I have already downloaded the new Redisti ng DX 9.0c
