Sorry to revive an old thread, I also have the black triangles issue. It also happens in FF7, FF8 and Spyro the Dragon, haven't tried other games. The Error occurs in Pete's OGL 1.76 and OGL2 2.8 plugins in EPSXE 1.52, 1.60 and PSXEVEN. I have Vista x64 and an X1600 pro.
I figure the problem might be solved here sooner than AMD/ATI can. I'm using Catalyst 7.11 and have used all versions since 7.2 and this problem has happened in all of them.
Using OpenGL extensions viewer all the tests work but it says I have no ICD installed, whereas on my other computer with a Nvidia FX5200 it does.
Does anyone know if Nikk's NextGL works, and if so how to set it up?
