[SOLVED] [Nvidia] INCREDIBLY poor rendering performance (<1FPS)

I am running kernel version 3.9.9-1, with Nvidia driver 319.32-2, on a Lenovo Y500 with two Nvidia 650M graphics cards running in SLI.

A benchmark with glxgears reports incredibly low FPS. Example output:

7 frames in 11.1 seconds =  0.632 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS
1 frames in 11.0 seconds =  0.091 FPS

Steam games, as well as the Dolphin Wii emulator, report similarly poor framerates.

Does anyone have any insight into what the issue might be, and how I might be able to go about fixing it?

You should start with upgrading your system.

Here are the latest versions from the repos

nvidia 325.15-5
linux 3.10.10-1

See if upgrading helps.

The reason I'm running out-dated driver and kernel packages is because the Lenovo Y500 seems to have issues with linux 3.10 and nvidia 325 whereby X fails to start.

You can see more here, if you're interested: https://bbs.archlinux.org/viewtopic.php … 1#p1324901

Either way, I figured out what the cause was. Turns out I was running the unagi compositing manager, which seems to conflict with the nvidia driver in some way that slows down EVERYTHING; I had noticed increased sluggishness in Chrome as well.

Killing unagi solved everything.

Marking as solved!

TIME TO GAME.
