Just try and use 6025 drivers with the 3286 opengl drivers (atioglxx.dll). I have used 6071, 6093 and the new 6094 catalyst drivers. I play Jedi Knight II outcast all the time and i was dissapointed by the performance of my card (Radeon 64 VIVO). It was then when i decided to make a test and use some old opengl drivers. And what do you know ... I found out that from release 6025 and above, there is no HyperZ for opengl !!! So i decided to use the opengl file from the 3286 drivers. The speed difference with the 3286 opengl driver is enormous when is compared with the 6094 ones. I do not know if this happens only for Radeon 64 VIVO cards, but you are free to try and see for yourself. Oh, by the way, you have to enable hyperZ with a tweaker (unituner).
