Hi,
try to disable W-buffer support.
From an older thread:
Hi,
I had the same problem after updating to the 9009 driver.
W-buffer support was broken and I had some more graphic errors (for example about half a second of flashing wheels of the broken truck in the background of the OFP menu shortly after starting).
After moving back to the 7189 driver from my Radeon 7500 CD (you can download it at support.ati.com) everything was fine again.
I'm using OFP version 1.42 and Win98SE.
Greetings,
Antonov
