Hello Phoronix,
I have been having the most annoying problem with Linux (particularly my 64bit Ubuntu distribution) for many years now.
It is as follows:
3D/2D accelerated OpenGL applications sometimes (but more often than not) use up all of my CPU! (screenshot from my old PC)
Yes, that is right. When I run a game or app such as xmoto, openttd, mupen64plus... It may use very little CPU (the way it's supposed to work) OR it will hog up all of the CPU.
Usually when I run such an application it will be hogging the CPU. When I close it, and reopen it, it will work fine. When I close it again and reopen it, it will be hogging the CPU again. It seems to be random.
It gets better:
I have actually bought a new graphic card (ATI now, had nvidia previously). The problem is still here.
I have bought a new motherboard. The problem persists.
I have bought a new CPU (AMD 3500+ previously, AMD X4 640 now). The problem persists.
I have bought new RAM. The problem persists.
I have wiped my /home and my OS and reinstalled it. The problem persists.
Basically I've bought a new computer (except the case, the PSU, the hard drives and the sound card) and reinstalled the OS, and I'm still getting this problem.
This leads me to believe that either I am cursed or that X is deeply broken in Ubuntu.
What do the experts of Phoronix have to say about this?
Thanks for whatever answers/help I may get!
