After upgrading from 14.04 (with fglrx) I am having trouble with OpenGL. I had to add the Padoka PPA since it supported OpenGL 3.3 (also GLSL 1.3). After adding the PPA I have OpenGL version 4.1 but not version 4.5 like with fglrx. But GLSL is still 1.3 (with fglrx it was 4.3).
I am having problems with some effects that are not working in SuperTuxKart (which require GLSL 3.0) and Minecraft SEUS lite shaders is also not working (which require GLSL 1.40 or 1.50).
- How can I upgrade the GLSL shaders version to 4.1?
- Is this a limitation of Mesa or something that I can fix?
My system specifications are:
HP Pavilion g7 2269wm
CPU : AMD A8-4500M APU
GPU : AMD Radeon HD 7640G (can play SuperTuxKart smoothly on settings between medium and high. Minecraft gets 60FPS :)
