GMA 950 Too slow

kirjushyk · #1 2009-11-04, 10:52 AM CST

All works correct, but very slow

For example, glxgears shows 250 fps.
When I installed Option "Tiling" to False in /etc/X11/xorg.conf, frame rate of glxfears decreased to 130 fps. I know, that my Intel GMA 950 i945 can more.

How I can fix my problem?

**Hlingler** · #3 2009-11-04, 02:12 PM CST

As has been pointed out many, many times before: glxgears is not a benchmark tool. Please define and/or quantify "slow' and provide results from a real benchmark tool (like hardinfo), and also provide other relevant specs for your hardware and software, if you want an intelligent response:
> Fedora Release and ARCH
> File: /etc/X11/xorg.conf
> Results of command: glxinfo | grep render
> Any relevant output from log file: /var/log/Xorg.0.log (do NOT post the entire file, just warnings/errors)
> Results of command: su -c 'lspci | grep VGA'
> ETC.

And please be patient - many members may be at work or otherwise unable to respond right now.

Ok, sorry

I have an Samsung NC10 Laptop with Intel Atom N270 processor with 1 GiB of RAM. I am using Intel video driver for my GMA 950 video adapter. Screen resolution is 1024x600. I am using Fedora 11, architecture is i586.

$ cat /etc/X11/xorg.conf

In some forums some people recommends to disable option "Tilings", but it's don't help =(

**Hlingler** · #6 2009-11-04, 03:22 PM CST

Try (re-)booting with kernel parameter nomodeset. See if that helps... .

kirjushyk · #7 2009-11-04, 03:31 PM CST

nomodeset is already set.

**Hlingler** · #8 2009-11-04, 03:57 PM CST

Well, again: I don't really see any problem so far. Unless you can define "slow" and/or quantify your system's (lack of) performance in some way, there is nothing wrong here, except that you think "... that my Intel GMA 950 i945 can more."

Some people can play HL2 on sammy nc10:

But I can not play even SuperTux, cause framerate is too small.

kirjushyk · #10 2009-11-05, 01:31 PM CST

I can run Gothic or Age of Wonders 2: Shadow magic on Windows.

Gödel · #11 2009-11-05, 02:07 PM CST

Try Fedora 12 or Ubuntu 9.10, the driver improvements are quite noticeable

(I also have an NC10, but can't test F12 on it just yet, I do remember F11 driver having slow performance in 3d benchmarks like glaxium, edit http://www.phoronix.com/scan.php?pag...item&px=NzIyMA )

kirjushyk · #12 2009-11-07, 04:45 PM CST

I increased the productivity in most applications by
1. installing 2.6.31 kernel,
2. dacspeed 400 in xorg.conf
3. clocks 400.0 in xorg.conf
4. option "Tiling" "True" in xorg.conf
5. option "SwapbuffersWait" "False" in xorg.conf
But there is bug in some OpenGL applications: Some triangles renders like with triangle's fan, using last vertex.
