GTX-780 Underperforming, problem with xorg.conf

[raffytaffy]

Motherboard - Asus Sabertooth 990fx r2.0
GPU - ASUS GTX780-DC02OC-3GD5
This is a home desktop computer, not a server.

Problem - I have installed the 343.22 Nvidia Driver ( I had same issues with drivers shipped standard with 14.04 LTS ) and I am unable to do the following things.

1. Start in Max Performance level 3, even though I added the option Option "RegistryDwords" "PerfLevelSrc=0x3322; PowerMizerDefaultAC=0x1" in my xorg.conf. The card starts @ 692MHz which looks like level 1 to me, I have to set it to max on every reboot. This is already set to "max" but upon reboot, it states 692, even though level 3 is highlighted.

Powermizer settings

2. I get horrible glxgears results, I googled around and folks were getting close to 20k with something like a 560ti

glxgears
48323 frames in 5.0 seconds = 9664.572 FPS
54361 frames in 5.0 seconds = 10872.043 FPS
54536 frames in 5.0 seconds = 10907.098 FPS
54322 frames in 5.0 seconds = 10864.253 FPS

My nvidia-settings lists my monitor as DPF-1

My xorg.conf. I am running 1 monitor. Any help is appreciated.

you need to configure things in gui.
2. save those settings to a nvidia-config-rc or whatever the default name for the file is
3. add this to a startup script or your choice: nvidia-settings --load-config-only

the reason being that those settings are per user not system wide.

also, if it was me i'd start with nvidia-default drivers first

Don't use glxgears as a performance check. gtkperf is a better comparison tool. I have a eVGA GTX 780 and I get gtkperf 4.5 with Prefer Maximum set and around 6. I leave it on auto most of the time anyway.

Try this: nvidia-settings -a [gpu:0]/GPUPowerMizerMode=1 > /dev/null

Put that command in your .bashrc or in one of the X11 configs. Works here.

Quitting..

is this the right way to run this ??

and less time is better ,,,,right

Yes and yes. I ran it here with a clean desktop (no open windows) and got 2.5-.6ish when performance is selected. It slows to 4ish using powersave mode.

Looks to me you're performing normally. Was there a specific reason why you think you're running slow or was it just glxgears? The reason you get 60fps is because you have Sync to Vblank set on. This caps the glx FPS at the monitor refresh rate. Try un-setting it and running glxgears again,

[oshunluvr]

Note the bold part: first one is with Sync to Vblank on, second is off.

stuart@office:~$ glxgears
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
304 frames in 5.0 seconds = 60.683 FPS
300 frames in 5.0 seconds = 59.998 FPS
300 frames in 5.0 seconds = 59.999 FPS

aaaaa I see ,,,,(sink to Vblank off)

103200 frames in 5.0 seconds = 20639.934 FPS
103028 frames in 5.0 seconds = 20605.551 FPS

witch is better ,,,,,having the sink to Vblank on or off .........for stability&performance
and no I did not think I was running slow (the OP was) just trying to learn as mutch as I can about setting up this Nvidia card (first one I'v had)

If your animations and videos are smooth looking with sync enabled, leave it that way. Your video card will use less energy and run cooler. If you see animation stuttering or tearing, change it.

The difference is how often the video card updates the monitor. At some point above vsync (usually 60hz) you may see "tearing" which is two or more copies of the same image at once during animation (video games, etc.). Also, I think when it reaches a high enough level, the tearing disappears again.

I think if your system slows down below monitor refresh rates for vsync then you see artifacts or blurriness and you don't want that. I suspect your video card (mine too - 780 GTX ) won't ever be dragged down by anything you're running.
