No render quality "very high"?
 

I switched from Ubuntu 12.04 x64 to Arch x64, but the problem with missing Very High Render Quality is still there.
I installed nvidia blob 304.37 on Arch.

When I manually set the Render Quality to the highest value (via game.cfg, diffed it with the game.cfg of windows client) the client notifies me that "libs/libglslang.so" can not been found and it disables all shaders. Where I get this library file (it works before the graphics update)?

Is the very high render quality still under development at Linux Regnum client?
(The thread where I posted this was closed ... so I re-posted it)

It does not work on OpenGl, guess it is using OpenGL 4.

AFAIK Very High render quality means the use of shader model 4 instead of 3.
btw. nvidia blob supports opengl 4, my graphics card too.

"libs/libglslang.so not found" thing belongs to vg_gl_validate_shaders option, but I'm sure I have this on before the update. Disable it and shaders are working again. Google says about libglslang.so something with a glsl compiler/validator.

PS: I want old fashioned Anti-Aliasing back. It looks much better, than blurring everything.

EDIT: The final question is:
Why is Very High render quality is not in the menu at OpenGL?

Shader 4 is replaced with high render.
