Serious bug in newer nVidia cards VESA VBE (Users)

posted by RayeR(R) Homepage, CZ, 20.12.2018, 02:20

Hi, I just tested one GTX 670 and found strange flickering in Build based games and Quake too (
This issue is spreaded to wider range of nvidia families at least 6xx to 9xx.
The problem is !nvest!gated (WTF, why is "inv3stigated" marked as bad word I cannot post?) here on VOGONS
It was found the bug is in VBE func. 07 for scrolling/page flipping. For Quake there's easy fix to disable page flipping by "vid_nopageflip 1" command entered in console. But for Build engine based games we don't know.
We also need to discover what all families are affected. Until GT2xx within it's OK. We need to test 4xx and 5xx and then latest 1xxx and 2xxx. So please if you have such card share test results.

DOS gives me freedom to unlimited HW access.
