Problems with bilinear and trilinear filtering in GZDoom

Postby armyman12345 » Fri Feb 03, 2017 10:34 pm

This doesn't happen if I have just the "linear" setting on. When I turn on bilinear or trilinear filtering in the settings, all textures and all sprites disappear. I assume this is because my video card is outdated. Is there any way to fix this?

What OpenGL version does your driver report?
This sounds like the function to generate mipmaps is broken on your system (without which some modes will not render any texture.)
Technically your card should support all what is needed.

2.1

EDIT: I've made it work now, I downloaded the drivers from the AMD website. But now it lags like crazy whenever I set the resolution to 1280x800 (my computer resolution). I never had this problem with previous versions of GZdoom
