Hi,
Trying out this GLSL shader and tweaking the values “Screen curvature - horizontal” and “Screen curvature - vertical” doesn’t appear to do anything. I’ve seen screenshots of this shader with some nice curvature effects, so I’m not sure what I’m missing.
Does anyone see the same issue? Running RetroArch v1.3.4 (stable) on Arch Linux.
Thanks!
EDIT: Never mind, I found I had to uncomment “#define CURVATURE”.
