Did you forget to set a bios in the firmware menu?

bonovox2k commented 10 months ago

with or without bios, change for direct3d and the image screen works

I've had a similar problem on my previous laptop where some programs' use of OpenGL resulted in black screens while others worked fine. So a followup question: does this also apply to other systems supported by ares?

i found the problem CRT-GEOM Filter shader master system + nvidia + opengl cause black screen !

Known shader problem, this is nothing to do with API/Driver/System and it all about lowres input image. @hizzlekizzle you have to finally fix this or delete shaders with this bug.

Given this issue is with a shader that ares does not include by default, would it be better placed as an issue over on the shader repo rather than ares itself?
