I got Sins a while ago (about a month ago), and it ran beautifully. I loved it. It was my new favorite.
Then Stuff went wrong. The game refused to run. I would go to start the game, my screen would go black, then I'd get an error from Windows saying that Sins has encountered an error (it didn't give any specifics).
I tried reinstalling. That didn't work. I tried a system restore. That didn't work. I tried a driver rollback. That didn't work. Then I updated to the latest driver pack. The game ran, but at a snail's pace. The menu screen was getting about 4 frames a second, if that. The actual game was slightly better; it probably got somewhere around 8-12 frames per second. Turning down my graphics settings didn't help at all. So I tried another driver rollback; which put me at square one where the game wouldn't even start.
I know my system can run the game at decent settings. It did for about 3-4 weeks.
Here's my rig:
AMD Athlon X2 4200+ 2.2 Ghz
1 gig ram
2X ATI Radeon X1650Pros in CrossFire
Windows XP
If anybody has any suggestions, it would be greatly appreciated.
