This is game related, now i have made a decided to leave XP and use Win7, but playing certain games, well it looks i have no choice but to use xp for my secondary rig, because many games are not working good at all. Kane & Lynch + Windows 7 + 9800GT + 181.20 drivers. ( new drivers does not help ) flicking, just a mess on screen, not to mention the game keeps crashing at the menu screen and oh the biggiest issue, the game did not come with a CD key, yes i bought the real version from gamestop. Matter of fact 2 other games which i own did not come with cd keys, like the Club by sega :shadedshu , the only good news, i can use my flatout utlimate carnage game cd key for those games. ( i buy all my games so don't fuss ). <------that is completely unrelated, just thought i would add that lol Anyways, Omikron The Nomad Soul : Artifacts for all 3 my cards in Windows 7, but in XP the game works just fine with my 9800gt anyway. Crysis & Bioshock , with or without a patch = Massive sound stuttering, game running like a POS. But oh wait, Crysis Warhead works just fine Ford Racing 2 & 3 = QUOTE from net, same problem " I run Ford racing 2 on my computer when it gives the following error message "WMA:347 Failed to create the Wma_source_filter " Looks like i will be using XP on my new build dual core soon. And just use Windows 7 x64 on my Quad.
