Graphics performance

I have good frame rate with opengl under windows.
DirectX crashes when I use Shader 3.0.

It disables the Shaders.

Yes, that's why I support the Open source Petition.

No, Linux have no other renderizer than opengl.

I read in ioquake3 lists about intention to move load from CPU to GPU by adding VBO and GLSL to engine. I never programmed with OpenGL and do not know what this will help, but anyway if this can help to get more fps and engine to be less CPU dependent it will be great.

Other point is alot linux users use NVidia cards because their drivers are better supported and less problematic. Would it help to make some module that uses Cuda or OpenCL to move some load to GPU again. If this is detected as possible ofc.

Multithreading can help to to split load across multiple cores.

I'm in holidays, here is an 4 years old pc with winXP and Xubuntu in dual boot, and an ati rv370 128gb video card:
- under Xubuntu, max performance is 12 fps in 1024x768, fixed pipeline, unplayable.
- under WinXP, directX9, 65 fps in 1024x768, shader 2, 55 fps with openGL.

What a pain to boot winXP to play the only linux native good mmorpg around...

I understand dbg_disable_shaders=1 disables the shaders! I wasn't too clear; what I meant was 1. Why is it in the debug section, and 2. What's the difference from fixed pipeline? Anyway, I have a nVidia GTX480 -- there should be absolutely no reason to turn down the graphics quality...

vg_renderizer will give an error if set to anything else I believe. dbg_disable_shaders I believe is what the "Fixed Pipeline" option for Shaders does, it just disables shaders for older cards that can't handle it and will cause graphical glitches or mega lag if you don't enable it, so I assume.

I have assumed the same, actually, and while graphics certainly are not the main reason why I play RO, the pedestrian implementation of OpenGL really annoys me, sseing what can be gone.

I've been fooling around a bit with OpenCL, and it's simply amazing. While lots of the stuff may not be directly relevant (after all, the GTX 480 is sort of a supercomputer on a board), it's disheartening to see what possibilites NGD have chosen to pass by. If they had a decent OpenGL implementation, they could really make a splash. (Posting that last remark here to avoid having to deal with the progamming illiterates in that other thread.)

I had some small problem early

Now it works better

jackruby:~$ nvidia-settings -g | egrep "OpenGL|rendering"
  direct rendering: Yes
  OpenGL vendor string: NVIDIA Corporation
  OpenGL renderer string: GeForce 8400 GS/PCI/SSE2
  OpenGL version string: 2.1.2 NVIDIA 173.14.22
  OpenGL extensions:

I modified the file game.cfg
dbg_disable_shaders to 1


dbg_disable_shaders=0
dbg_disable_shaders=1


My file "game.cfg"

I still have to find how to avoid the crucifixion
