I’m trying to setup an older machine as an emu box running Windows 7, and I’ve been encountering some weird graphical glitches and errors when trying to use shaders with the gl driver. More than one shader pass causes the screen to go black, and a lot of the shaders just display weird garbage. What version of openGL is required?
Should be 2.0+. Vendor drivers can be pretty bad, though.
Hmm, what (if any) are the alternatives to using the vendor driver? I’m pretty sure this card should support OpenGL 2.0…
The other options are d3d9 driver, which should be able to run most Cg shaders, or d3d10/11, which run slang shaders. For whatever reason, vendor drivers are usually much better at directx than opengl.
