Low FPS with glxgears !!!!!

Hi!

Installed arch linux a few days back, hoping it would a fast lightweight system, however I only get 8-7k FPS with glxgears!

In a Ubuntu instalation that I have I get 28k FPS! And Ubuntu is (supposedly) heavier than arch...

Does anybody hava an idea of what may be causing this? Some option o xorg.conf maybe? Or some bad driver?

EDIT:

My specs:

Intel C2D E6420 @ 3200Ghz
eVGA 8800GTS KO ACS3
2x1Gb Corsair XMS2 @ 800Mhz
Seagate Barracuda SATA II 320Gb 7200rpm

nvidia v173.14.12 driver from the /i686/extra/ repository

You haven't given us any useful information like what graphics card you have, what drivers and their versions you have installed, etc. We're not psychic!

Speak for yourself...pffft

Me too, I used to get a lot of FPS in Ubuntu, but not in Arch for some reason :S
I have 8800gt with nvidia drivers from nvidia site.

Regnum Online?

Its a cpu bound game, not the best way to test your video card.

I have the same problem

GeForce 8600 GT 256 MB

I have a 7500le (le stands for light edition)

And i get this.

13121 frames in 5.0 seconds = 2624.159 FPS
13329 frames in 5.0 seconds = 2665.669 FPS
13516 frames in 5.0 seconds = 2703.039 FPS
13516 frames in 5.0 seconds = 2703.153 FPS

13510 frames in 5.0 seconds = 2701.819 FPS
13514 frames in 5.0 seconds = 2702.800 FPS

Yes.. *i think* you should more fps.. anyway you should never use glxgears as a benchmark.

You could use nexuiz instead.

Make sure you dont force vsync both in the nvidia-settings and in nexuiz settings. There's a bug that kills your fps if you enable it in both places. Not sure about other games.

Re: Low FPS with glxgears !!!!!

Glxgears is not a benchmark. I repeat. Glxgears is not a benchmark.

If you noticed a speed decrease from Ubuntu in 3D applications or compiz that's another story, but if we are just talking abou the fps just forget it.

Re: Low FPS with glxgears !!!!!

What is glxgears used for?  It too seems to be way slower on my Arch setup (~2800 FPS) than Ubuntu (~6000) as well, but I certainly can't really tell performance-wise so I never worried about it.

Re: Low FPS with glxgears !!!!!

I think I might be having a real problem...

Failed to initialize TTM buffer manager.  Falling back to classic.
369 frames in 5.0 seconds = 73.794 FPS
375 frames in 5.0 seconds = 74.838 FPS

I have a integrated intel card (945G) and glxgears gave me about 1000 FPS before xserver 1.5 and xf86-video-intel 2.4.x

Re: Low FPS with glxgears !!!!!

*shurgs* I don't know if this helps for sure, but since you are using intel, issue in your terminal:

[andrew@Aprz ~]$ export INTEL_BATCH=1

If there is a noticeable improvement in FPS, which there should be, then put it in ~/.bashrc.

[andrew@Aprz ~]$ sed -i '1 s/^/export\ INTEL_BATCH=1\n/g' ~/.bashrc

Which if you open up ~/.bashrc then you should notice "export INTEL_BATCH=1" at the beginning of the line. Miue looks like this:

export INTEL_BATCH=1
export MOZ_DISABLE_PANGO=1
alias ls='ls --color=auto'
PS1='[\u@\h \W]\$ '

Always like to have an excuse to use sed (probably would've been faster just to open up vi and type it in there myself, lol, but sed makes you feel cool).

Have you also checked the difference between opening glxgear as root between your non-root account. Sometimes, the problem could lie that your user is not in the video group like it should be:

[andrew@Aprz ~]$ sudo gpasswd -a andrew video

Since you have used Ubuntu then I am sure you know how to use sudo.

Hopefully you are using xf86-video-intel instead of xf86-video-vesa also. *shrugs* Just throwing stuff out there.

Re: Low FPS with glxgears !!!!!

any thoughts for this problem? I find it really strange because it is a huuuuge difference (20k)... I'm afraid there is something wrong with my settings...

Re: Low FPS with glxgears !!!!!

I have an 8800GTS too and I get ~6K, as I already told you these numbers mean nothing, they even change if you resize the window.

Re: Low FPS with glxgears !!!!!

afonic,

I realize that it isn't a benchmark, but I am just curious what the FPS numbers tell you at all.  Certainly a 2-fold difference is at least a slight indication of something, isn't it?

I just think it's a huge difference from 28k to 8k...

Re: Low FPS with glxgears !!!!!

It is a huge difference, and it deserves an answer. There's different xorg major versions (and of course patchsets - Ubuntu patches heavily) involved (xorg is a huge, complicated beast which has bugs of its own), plus the interesting rumour on the nvidia forum I vaguely remember seeing which questioned whether nvidia were having difficulty maintaining performance in their "unified" 173/177 drivers whilst supporting all the latest weird nvidia card models & sub-models.

Re: Low FPS with glxgears !!!!!

Thing is, I have both Ubuntu kai Arch. I have 24k fps in Ubuntu and 6k in Arch. But in Guild Wars I get around 80fps in both, so...

Re: Low FPS with glxgears !!!!!

I have 24k fps in Ubuntu and 6k in Arch.

Cool, is this a dual-boot? You can be the guinea-pig

Which nvidia driver are they both using? Exact version, pretty please. Both 32-bit installations?

Which Ubuntu version? Which graphics card (8800GTS is not descriptive enough, e.g. the 640mb version is, just to confuse the heck out of us, slower than the more recent 512mb version)?

I'd also like to see the xorg.conf of both installations.

I suspect, based on my own little tests with a spare hard drive, that Nvidia's latest drivers cause the difference.

Re: Low FPS with glxgears !!!!!

Can you people please use REAL benchmarks instead of glxgears. Unless you're noticing slow performance elsewhere, there's nothing wrong with your systems.

Re: Low FPS with glxgears !!!!!

If you read the posts, most of the people here acknowledge that glxgears isn't a benchmark.  Simply repeating "glxgears is not a benchmark" has nothing to do with rsambuca's question and what brebs is trying to figure out.

No. This significant slowdown in glxgears is interesting and piques our curiosity.

If it bores you, then go to a different thread. Stop trying to earn brownie points from repeating the "glxgears is not a benchmark" mantra. Yes we know. Nobody's job or life depends on this.

Re: Low FPS with glxgears !!!!!

When I have time I will run some glxgears non-benchmark tests.  The distros I  currently have installed are arch32bit, Ubuntu Gutsy 64bit, Ubuntu Hardy 32bit, and two other distros that I haven't touched in months.

Re: Low FPS with glxgears !!!!!

Just for the record, I think we, who have intel cards, are pretty much screwed up for the time being (or doomed to compile tip versions): http://bugs.gentoo.org/show_bug.cgi?id=237468

Re: Low FPS with glxgears !!!!!

Thanks to all who are saying "we know it's not a benchmark".. I've always been curious about glxgears performance, and have been hearing the "it's not a real benchmark" for years

though i always use it as one as soon as i install X on any computer.

currently i'm getting around 2.5k fps.. i've seen it go as low as 500 fps, as high as 3.1k fps.  i have a quadcore q6600 @ 2.40ghz, geforce 9500 gt (512mb, 550mhz bus gpu and mem), 177.78 drivers (from aur, nvidia-beta and nvidia-utils beta), compiled with -march=core2, -j6)

on my older athlon xp 3200 (running at 1.5ghz unfortunately (chip is dying), with geforce 6800 (512mb), and i believe 177.1x driver (older), i get anywhere from 1.6k - 2.5k, so similar fps on both.

Re: Low FPS with glxgears !!!!!

I just wish that some of these experts would answer our questions and tell us what glxgears actually does rather than just say "it isn't a benchmark", eventhough we already acknowledged that fact.
