Woah, okay. Scratch what
I said at the beginning of this thread.
Upon downloading Pete's new OGL2.9 plugin, I went to test it out and started experiencing black triangles. I don't think it's Pete's plugin that's to blame. Lately, I've only been using P.E.Op.S soft plugin and it's been a long while since I used the OGL2 plugin. I think the last time I used it was when I played through Final Fantasy IX two summers ago.
Right now I'm using Omega v4.8.442, based on Catalyst 7.12. I haven't tried the new drivers yet. When I was playing Final Fantasy IX I was using drivers older than the ones I'm using now.
This is very interesting. So Catalyst v8.5 fixes these problems? Ah well, it doesn't matter, I'm getting an 8800 soon.
