games are slow

the tester · 07-06-2010, 11:53 PM

when i try to play any game in slackware
the game is slow
i played these games on another distributions and it worked fine
i don't know why this happen in slackware
i have:
nVidia Corporation C73 [GeForce 7050 / nForce 610i] (rev a2)
CPU: Intel(R) Pentium(R) Dual CPU E2200 @ 2.20GHz

Do you have Nvidia driver installed?

Check if you have direct rendering enabled.

kingbeowulf · 07-07-2010, 12:32 AM

Did you install the proprietary nvidia binary driver? The open source driver is too slow for games on many GPU.

the tester · 07-07-2010, 11:05 AM

yes i installed my Nvidia driver
but the problem is n't in my open source driver
because like i said i tested these game on another distribution and it worked fine
is there a solution?
i don't want to leave slackware

What's the output of:

Quote:

glxinfo | grep render

Just to make sure that the nvidia driver is working properly, can you post the output of:

Code:

glxinfo | grep -i direct

It should report something like:

Code:

bash-4.1$ glxinfo | grep -i direct
direct rendering: Yes
    GL_EXT_Cg_shader, GL_EXT_depth_bounds_test, GL_EXT_direct_state_access, 
bash-4.1$

The key info there is direct rendering: Yes

EDIT: I did not see the post from sycamorex before I posted this. In any case, either command (his or mine) will work for this purpose.

Is 'direct rendering: Yes' enough?

Code:

sycamorex@sheldon:~$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: GeForce 7600 GT/PCI/SSE2

I might be wrong here, but shouldn't OpenGL renderer string list your hardware (to indicate hardware rendering), as opposed to 'Software Rasterizer' (Software rendering)?

Yeah, I think it's true:

Code:

bash-3.1$ glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: GeForce 8800 GTS 512/PCI/SSE2
    GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image, 
    GL_NVX_conditional_render, GL_NVX_gpu_memory_info,

tommcd · 07-07-2010, 11:48 AM

For what it's worth, here is what I get when I run:

Code:

glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: GeForce 8600 GT/PCI/SSE2/3DNOW!
    GL_NV_conditional_render, GL_NV_copy_depth_to_color, GL_NV_copy_image, 
    GL_NVX_conditional_render, GL_NVX_gpu_memory_info, 
bash-4.1$

My point was that the line 'direct rendering: yes' might not be enough when diagnosing the problem. Some time ago I had a problem with my ATI driver. The output did show 'direct rendering: yes' but below it said 'software rasterizer', which indicated that the driver wasn't correctly installed and it wasn't actually capable of 3d rendering.

adamk75 · 07-07-2010, 12:12 PM

Correct, these days you need to check for both direct rendering and the renderer string. Checking for just one or the other is not enough as you can get direct rendering with the mesa software rasterizer, and you can have the correct opengl renderer string even when using indirect rendering.

well, it gave me yes
how can i check this renderer string.
