Default 100% cpu load when using OpenGL

Hi,

I have SuSE 9.1 pro with nvidia drivers, which works pretty well. The problem is that when I run a program that needs openGL (like glxgears, Enemy territory or GL-117), the cpu load rise up to 100%, with apparently no reason. The cpu is a AMD athlon 3000+ and the mobo is a ASUS a7n8x-e deluxe. żAnyone else with this problem?

PD: Ups! I forgot.. the card is a GeforceFX 5200 3D

Have you synched the framerate to vertical refresh ?
Probably not, so the programs are just trying to render as much frames as possible.
If applications are too fast (say, over 100fps), you can reduce significantly the CPU usage by checking the 'Sync to VBlank' box in the nvidia-settings programs provided by the drivers. Moreover frames won't look splitten anymore.

Is this normal with all mobos or only with some cpu-mobos combinations?
I say that because the normal temp of my cpu is 54șC and after 2 minutes of playing any game the temp is 58șC...

This is normal for every single motherboard CPU combination I have ever seen.
It is also normal that the CPU temperature changes from idle to max CPU.

About every single 3d game will use 100% or try to if they can. It's normal in linux and other OS's like Windows.

I'd relax. The Athlon is not supposed to suffer permanent thermal damage until it hits 85șC. Naturally, if you were seeing regular temps of over 70șC, that would be a cause for concern, if not immediate panic, but 58șC is healthy enough. The Athlon 3000+ can't be expected to run ice-cool.
