After updating from RA v1.9.0 to v1.9.1 my CG shaders don’t work anymore. I’m using the GL video driver, but it seems to force to GLSL:
[INFO] [GL]: Default shader backend found: glsl. [INFO] [Shader driver]: Using GLSL shader backend. [INFO] [GLSL]: Checking GLSL shader support ... [WARN] [GL]: Stock GLSL shaders will be used.
I also noticed that the v1.9.1 (x64) package only comes with glsl shaders. Is there a reason for this? Have CG shaders been discontinued?
EDIT: I suppose this is the answer:
- CG: Old, deprecated format. Might not be available if RetroArch is built without Cg runtime support.
- GLSL: Shader format available to OpenGL. Wide range of platforms including phones and tablets.
- Slang: New and recommended shader format, when available. Compatible with Vulkan, Direct3D 10/11/12, OpenGL Core, WiiU and Metal renderers.
