System spec opteron185 2gb ram HIS x1950pro 512mb AGP asus a8v deluxe All drivers updated on a fresh format. I have this problem. i read the fix to change it to pci-pci and it works. However i have reduced performance in FPS, infact it performs worse then my original x800pro. and it worked so well (before my pc stops working) when i had it cpu-agp. I think i read the original fix on this forum, but im not sure, so if it is im hoping for some more advice. I have vista Ultimate ready to go. but i dont want this problem to be on vista. has anyone ever experienced this problem on vista? anyone who has truely experienced this problem knows that the pci-pci is the only fix and has nothing to do with latest drivers or anything else (even tho my pc is bang uptodate). I was hoping people would say "hey i dont get this problem after i installed on vista". but havnt found any, or people saying "i have the same problem on both xp and vista, life sucks". If anyone knows of a better fix or if vista could be my ticket out of this £150 mess i got my self into. let me know!
