Question by Guitar80EP · Feb 24, 2016 at 09:45 AM · glitchcustom-shadergraphics cardgeometry shader

Geometry Shader Glitches on Intel HD Graphics

I have a grass shader (one pass of surface + one pass of vert/geometry/fragment) that works on my laptop when plugged into a power supply, but when I run the laptop on battery I get weird warping and time speed up glitches.

I looked into the problem and found out that on battery my NVIDIA dedicated GPU isn't running, but instead my laptop is switching to Intel HD Graphics 530. Is this a glitch with Unity 5.3.2.f1? I would think the shader should function the same on either card, just slower or faster.alt text

@Guitar80EP Did you by chance have any luck with this? Having my own oddities with a geometry shader on an Intel GPU (HD 520 in my case)
