Yeah, so...I have been having some problems with my ATI 3870. Running a game that it should run pretty smoothly, Half-Life 2 Episode 1, it does...with caveats. The optimal settings seem a bit awry, at least I thought so: No AA, Trilinear filtering. I set it to the standard I did with HL2 on my old ATI X800XT: 4x AA, 8x AF. The frame rate didn't take as much a hit as you'd think it would, even with HDR on. So I thought things were fine. But that's when things hit HARD: The game crashed repeatedly on DX8 vertex buffer errors and Direct3D 9 errors. Sometimes, I even get a BSOD, which doesn't happen to me out of random. It got so bad that one point of the game (the point right before the final battle at the train depot) just would not load and crash. I first thought it was the AA (because I remember there being something on AA and HDR not mixing). But even then there were still problems. I then checked it back from AF to Trilinear, and it worked fine.
Here's my question: Why was there such an issue with the AF in the first place? Are the 3800 cards having issues rendering AF now? My X800XT, back when it was able to render properly, handled AF just fine. What is the issue?
Looking it over now, I just ran through HL2:EP2 (which has an advancement of the Source Engine) on 4x AA and 4x AF, without any crashes (except maybe one). Looking it over, it prolly was just the game itself. I thank you for your help, though. (Though I must ask: Is the text rendering in odd colors bad?)
