Nvidia driver FPS problem
 
1 Attachment(s)
Hi forum,

I've reinstalled my freebsd desktop and i'm having a little problem.

On my old installation when I ran glxgears I had 33k FPS per 5s but now im only registering 7k FPS.

I've attached glxinfo, xorg.conf and nvidia-settings.

Thanks in advance for the help.

Cheers

glxgears is not a benchmark.

Hi,

I know glxgears is not a benchmark but 6/7k to 33k is a difference that one can suspect.. I play multiplayer opengl FPS games and i notice some degradation of game performance and some mouse lag..

Thanks

Cheers

Do you have benchmarks using any of those games showing the performance difference? Can you run nvidia-bug-report.sh and generate a bug report and post it here?

Are you running a Window Manager with Composing turned on? That'll drastically drop your framerate.

Hi,

Thanks for the input.

This is weird but as of 180.60 nvidia-bug-report.sh is not shipped with the port.

Yes indeed, that's one of the differences. I'm using kde4 now.

PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
1134 alex 1 46 0 106M 47520K CPU1 1 0:06 4.05% kwin
1627 alex 10 44 0 98044K 83888K ucond 1 0:00 3.66% firefox-bin
1074 alex 1 45 0 363M 30144K select 1 0:07 0.39% Xorg

I think one of the issues was [DirWatch] PollInterval from KDE. Every time it ran i't sucked 50% of CPU. Every now and then I'd feel a lock in the game for 1/3d of a second or smth like that which used annoyed me. I've tuned this parameter and it happens less.

Another thing is the general FPS drop i got from freebsd 7.0/KDE3. I can't recall the version of the driver :\ The system was configured/built exactly as it is now.

When i tried to see why i seemed to have less FPS while gaming i came across this huge drop on glxgears frames and this new message about "Running synchronized to the vertical refresh.", which i think it didn't showed before.

Many thanks

Cheers
