Random drastic FPS drops in games and glxgears.

[mikul]

Is there anyone else that gets random drastic FPS drops in all games lately? Or have an idea on why it happens?
For example Quake Live and Quake 3, 4 i have perfect FPS for a couple of minutes and then suddenly it drops to 20-40 FPS for about 15-25 seconds. Then perfect 125 FPS again.
It have been going on for a couple of weeks now (probably started after some update i can't remember)
Everything worked perfectly before.. and then one day i noticed it started to happen.
First i thought it was the graphic card that couldn't take it anymore, but that's out the window now, because yesterday I bought a brand new card, but still got the same problem.
Have tried different versions of NVIDIA drivers but no difference.

I'm on the edge of what i can take.
I'm thinking of switching OS, but that's just sad, because i like Linux Mint.

Graphics: Card: NVIDIA Device 11c6 bus-ID 02:00.0 X.Org 1.11.3 driver nvidia Resolution 1440x900@60.1hz
GLX Renderer GeForce GTX 650 Ti/PCIe/SSE2 GLX Version 4.2.0 NVIDIA 304.60 Direct Rendering Yes

I ran glxgears for a while and i got this results: (steady 16000+ almost the whole time and then suddenly down to 3000 for 15 sec)

Code: Select all

85023 frames in 5.0 seconds = 17004.451 FPS
84810 frames in 5.0 seconds = 16961.963 FPS
83652 frames in 5.0 seconds = 16730.387 FPS
83610 frames in 5.0 seconds = 16721.969 FPS
83664 frames in 5.0 seconds = 16732.672 FPS
83079 frames in 5.0 seconds = 16615.633 FPS
17635 frames in 5.0 seconds = 3526.929 FPS
16141 frames in 5.0 seconds = 3228.033 FPS
49373 frames in 5.0 seconds = 9874.528 FPS
83735 frames in 5.0 seconds = 16746.939 FPS
83815 frames in 5.0 seconds = 16763.000 FPS
83754 frames in 5.0 seconds = 16750.791 FPS
83677 frames in 5.0 seconds = 16735.211 FPS
45459 frames in 5.0 seconds = 9091.363 FPS
17522 frames in 5.0 seconds = 3504.276 FPS
16073 frames in 5.0 seconds = 3214.465 FPS


EDIT: updated the graphic drivers to the latest one from NVIDIA, but still same problem.

Hi,

I have the exact same problem. I posted it in the forum and people talked down to me like it's my fault. LOL. I can see why people don't migrate from Windows to Linux now. I mean, the OS is awesome but the community thinks they are a bunch of experts because they know what sudo does. LOL, it's just cracks me up; I think the only person that should take that approach is Trovalds himself.

I re-installed about 5 times, but the fps hasn't changed - it really sucks. I play one game - Armagetronad and it's a very light game to play on and the fps jumps down to 20 and 30 fps and starts at about 800 - something is definitely wrong with this setup it's not the drivers, it's the distro, the same older drivers work better in Maya - this thing started after I did the backports I believe. I had the same exact problem after installing 14 which is why I went back to 13, I think it's time to try out Cinn Arch, after all, the thing that makes Linux Mint so great - is in fact Cinnamon. Other distros have it and without Ubuntu as their base. I think Linux Mint just got replaced by CinnArch on my machine. And if that doesn't work, it's Windows 8 for me. Bye now.

to trouble shoot the issue i would also be running a terminal with top in it so you can see what is coinciding with the FPS drop. it's obviously some process that causes the FPS drop, just have to find out which one.
