Hello guys. I've got a standard Voodoo 5 AGP that is showing horizontal banding when in 3dfx rendering. I first noticed it in Unreal Tournament (UT99) in 3dfx mode (3dfx mode only, DirectX mode is fine). I also started noticing it in other glide titles (ex. Need For Speed II SE). Knowing something about how the Voodoo 5 works, I believe it is an issue related to the internal SLI mechanism of slicing up the image to each chip for processing.
When I set rendering to one chip only, the issue goes away. If I enable antialiasing, the issue also goes away (strangely enough). Return to Castle Wolfenstein / Star Trek Elite Force / Quake 3 do not seem to exhibit any banding issues, but I think it is because they use OpenGL.
OS: Windows 98 SE
RAM: 512mb
CPU: AMD 3000+
Drivers: Amigamerlin 2.9
I looked over the board and it appears fine, but I guessing there is a component (maybe a cap) that needs replacing. I've done cap replacement before, so I'm not scared to do it, but wanted to ask if I am on the right track with my diagnosis before doing cap replacement?
Thanks.
