I have a Geforce 8800 GTS 640MB I recently downloaded the smoke tech demo for the 8800 from nvidia and omg i love it its awesome! But I was wondering can u can change settings and stuff cos in the video its all anti aliased but mine isnt! and I swear I read somewhere someone talking about the settings but I cant find them! also can I use this as a screen saver some way? Also I got the frog tech demo as well the video for that looks so fun! I wanna stretch the poor lil froggy, but I installed it and tried to run it and it said it couldnt find a dll, ummm d3d10.dll i think it was or something like that, ill check when i get home(at skool atm) im presuming that this is a direct x 10 thing and that i need vista to run it only running xp home sp2, planning to get vista before crysis though!
