I have just uninstalled XP & installed Vista Home Premium (x64).
When XP was installed, COD 5 ran like a dream. No lag/stuttering whatsoever, but now that Vista is installed I seem to be experiencing problems.
There is definitely some lag ingame now that I've installed Vista. You probably wouldn't even notice it if I made a recording, but knowing it's there and seeing it lag every so often is EXTREMELY annoying. I know for a FACT 100% that it wasn't there when XP was installed. Now I remember last time I installed Vista, a few months back, a game I was playing at the time (Guild Wars) which ran smooth as hell in XP became extremely unstable & I suffered lag/stuttering etc in Vista, therefore I reinstalled XP.
I don't particularly want to have to reinstall XP again, as the number one reason I purchased a 64 bit OS was for games, but if it's just gonna cause lag/stuttering then I feel I may have wasted my money.
I can't understand WHY exactly it'd run perfectly fine in XP but not in Vista 64 bit (which is supposedly better for gaming). I spoke to somebody and they said something like "32 bit games/programs run in an emulation mode on 64 bit Vista". Could this have anything to do with it? The annoying thing is, you guys probably have no idea how to help me and therefore I feel I'm probably wasting my time, but if I can get any help to sort this problem out, it'd be greatly appreciated.
What are your specs?
Is the lag in single player or multiplayer?
CPU - Intel Pentium D 820 2.8Ghz (Outdated I know) Video Card - 640mb Nvidia Geforce 8800GTS (all latest drivers installed) Ram - 2gb DDR II (waiting for another 2gb to arrive in mail) OS - Windows Vista Home Premium (x64) PSU - Thermaltake Toughpower 750w Resolution - 1440x900
Yes not the best specs in the World, but the game ran flawlessly on XP even on max settings. Now it's in Vista, it's started lagging
The lag is in singleplayer AND multiplayer.
I didnt like CoD 5 much, but WoW isnt the real "CoD 5". CoD 5 is due soon.
