Hello list, after some more experiments I have discovered following explanation for my low fps rate.
With nvidia kernel module and with "nvidia" in driver section of XF86Config-4 as well with Load "glx" and _without_ Load "dri" and _without_ Load "GLcore" : If I run setiathome and glxgears at the same time, I get 10 fps. But if I kill setiathome and run only glxgears, fps immediately jums on 2500 or even 4000 at times. >From /proc/cpuinfo - .. model name : AMD Athlon(tm) 64 Processor 3000+ stepping : 0 cpu MHz : 1808.838 cache size : 512 KB .. Now I thought that it is the hardware on the graphics card which should take all the load for 3D (ie. glxgears) not the cpu. So either/both I was wrong with this concept or something is wrong with my setup. Can anyone please help me to clarify this issue? So after a moment a came to the idea to test wheather nv driver would give different results. So I have changed my XF86Config-4 in two respects. First I have replaced "nvidia" with "nv" in driver section and than I have also uncomented Load "GLcore" and Load "dri" while at the same time I have removed (read commented out) Load "glx" line. But now I am not able to run glxgears at all, since it complains about "Xlib: extension "GLX" missing on display ":0.0".". So I have searched in the /var/log/XFree86.0.log and found these lines: ... (II) LoadModule: "GLcore" (WW) Warning, couldn't open module GLcore (II) UnloadModule: "GLcore" (EE) Failed to load module "GLcore" (module does not exist, 0) ... Naturaly I have continued my research with the command: $locate GLcore /usr/lib/libGLcore.so.1 /usr/lib/libGLcore.so.1.0.7174 /usr/X11R6/lib/nvidia/libGLcore.a.xlibmesa $ so now I see there is something strange about this.
