Nvidia & glxgears, am I too slow?

I think I have my slack box set up as well as it can be. The one thing that bothers me though is the video. I believe I have everything set up right, but glxgears seems so slow compared to the numbers other people seem to be posting. Here's a sample:

Code:

shilo@shilo:~$ glxgears

393 frames in 5.0 seconds = 78.600 FPS

414 frames in 5.0 seconds = 82.800 FPS

416 frames in 5.0 seconds = 83.200 FPS

417 frames in 5.0 seconds = 83.400 FPS

415 frames in 5.0 seconds = 83.000 FPS

318 frames in 5.0 seconds = 63.600 FPS

164 frames in 5.0 seconds = 32.800 FPS

162 frames in 5.0 seconds = 32.400 FPS

163 frames in 5.0 seconds = 32.600 FPS

161 frames in 5.0 seconds = 32.200 FPS

164 frames in 5.0 seconds = 32.800 FPS

159 frames in 5.0 seconds = 31.800 FPS

164 frames in 5.0 seconds = 32.800 FPS

161 frames in 5.0 seconds = 32.200 FPS

154 frames in 5.0 seconds = 30.800 FPS

X connection to :0.0 broken (explicit kill or server shutdown).

The 32 FPS is where I maximized the window running the gears.

My specs:

Slackware -current
2.6.5 kernel
Vanta TNT2 16mb Video card
Nvidia driver
800mhz AMD Athlon
256M ram

Here's a sample from my /etc/X11/xorg.conf

Code:

# This loads the GLX module

    Load      "glx"

# This loads the DRI module

#    Load      "dri"

# Device configured by xf86config:

    #VideoRam    16384

    # Insert Clocks lines here if appropriate

EndSection



(snip)



# Section "DRI"

#    Mode 0666

# EndSection

and here's most of the output from glxinfo:

Sorry to have such a lengthy post. Is this the best performance I can expect given my "top of the line":rolleyes: hardware?

Thank in advance,

I dont' know much about nvidia, or the Riva TNT card... But 80 fps seems a bit slow to me.

For a little reference, I get about 2000 fps with glxgears from my Radeon 9000 Pro.
No, not the same class, but that tells you why I think 80-32 is too slow.

However, it does say direct rendering is enabled. Which is good, and usually means you're working fine.

I would try uncommenting the DRI section at the end of your XF86Config file.

--Shade

Thanks for the quick response.

I uncommented the lines

Code:

# Section "DRI"

#    Mode 0666

# EndSection

No change.

Code:

shilo@shilo:~$ glxgears

412 frames in 5.0 seconds = 82.400 FPS

421 frames in 5.0 seconds = 84.200 FPS

421 frames in 5.0 seconds = 84.200 FPS

416 frames in 5.0 seconds = 83.200 FPS

285 frames in 5.0 seconds = 57.000 FPS

163 frames in 5.0 seconds = 32.600 FPS

163 frames in 5.0 seconds = 32.600 FPS

162 frames in 5.0 seconds = 32.400 FPS

160 frames in 5.0 seconds = 32.000 FPS

162 frames in 5.0 seconds = 32.400 FPS

X connection to :0.0 broken (explicit kill or server shutdown).

A critical factor is whether you are running this in a minimized window, or a full screen. The full screen numbers will be considerably less. -- J.W.

Hi shilo...

Was just wondering if you upgraded your kernel. And if so...did you reinstall the nvidia driver. The numbers that you posted look extremely slow. Your xf86config file looks fine. I am using an nvidia card and my numbers are:

4432 frames in 5.0 seconds = 886.400 FPS
10209 frames in 5.0 seconds = 2041.800 FPS
25322 frames in 5.0 seconds = 5064.400 FPS
4328 frames in 5.0 seconds = 865.600 FPS
18886 frames in 5.0 seconds = 3777.200 FPS
22175 frames in 5.0 seconds = 4435.000 FPS
19288 frames in 5.0 seconds = 3857.600 FPS
25525 frames in 5.0 seconds = 5105.000 FPS

My computer is decent but nothing state of the art.

By the way...which driver did you install from nvidia?

Thanks, I figured that out.

imagreg-

Yes, I upgraded my kernel to 2.6.5. I upgraded my Nvidia drivers right after that. I installed the 5336 drivers.

Code:

shilo@shilo:~$ lsmod

Module                  Size  Used by

nvidia              2070120  12

Yeah, I was kinda thinking the numbers seemed slow, too.

do you have DMA enabled??
try this..
from a term window type

Code:

hdparm -tT /dev/hd??

just replace the ?? with your hard drive number........
post your output...........

320mb-

Yes, I have DMA enabled.

Code:

root@shilo:/home/shilo# hdparm -tT /dev/hda

 

/dev/hda:

 Timing buffer-cache reads:  484 MB in  2.02 seconds = 239.76 MB/sec

 Timing buffered disk reads:  76 MB in  3.06 seconds =  24.86 MB/sec

root@shilo:/home/shilo# hdparm -tT /dev/hda1

 

/dev/hda1:

 Timing buffer-cache reads:  368 MB in  2.00 seconds = 183.66 MB/sec

 Timing buffered disk reads:  80 MB in  3.13 seconds =  25.57 MB/sec

root@shilo:/home/shilo# hdparm /dev/hda

 

/dev/hda:

 multcount    =  0 (off)

 IO_support  =  1 (32-bit)

 unmaskirq    =  1 (on)

 using_dma    =  1 (on)

 keepsettings =  0 (off)

 readonly    =  0 (off)

 readahead    = 256 (on)

 geometry    = 59320/16/63, sectors = 59794560, start = 0

You just included your driver-setting in your XF86Config

Thus I can't see if you have the driver activated in the screen-section. This might be the problem.

Here's the start of my screen-section:

Code:

Section "Screen"

    Identifier  "Screen 1"

    #Device      "VESA Framebuffer"

    Device      "Nvidia driver"

    Monitor    "My Monitor"

Chances are that you're still running your screen with the VESA Framebuffer if you didn't change. VESA Framebuffer is slow...

I think you also need to uncomment

# Load "dri"

in the first portion of XF86Config

Yep, thats about it for a card this old.

I'm not so sure about that Aussie. When I ran without hardware acceleration I got around 300 fps on glxgears on my athlon xp 2000+

80 fps with hardware acceleration on a 800mhz seems very low even for an old card like that.

Thats all u can get from TNT2. I too have a nVidia Riva TNT2 (32MB) and 85fps in window mode is the maximum i can get in any distro (so i figured out that its not distro related) .
May be its time for me and u to buy a state of the art Videocard ;-) !

I too have a vanta 16mb and im able to get around 390FPS in glxgears. Heres what I did.

in your ~/.bashrc add this to turn off vsync

"export __GL_SYNC_TO_VBLANK=0" without quotes.

If you dont have .bashrc then your have to create one by typing

"touch ~/.bashrc"

Then set xfree to 16 bits instead of 24 bits.

Thats it.
