Urban Terror is slow (low fps)

[OnlyWhisky]

I have kubuntu 8.04.1 with kde4.1rc1.

My hardware:
Celeron2800, 1024MB RAM, AGP8 NVidia GeForce 6800GT 256MB.
driver is: nvdidia, 173.14.09
in xorg.cfg nvagp is set to 8.

In Urban Terror I have low fps when playing with opponents, when shooting and with snow effects, etc. Fps sometime down to 8-20. In normal case (no other players and now effects) it is 85 (maxfps).

I have tried different video settings with no success. What could it be?

Can you post the ouput of glxgears?

Bye!

Here it is.
$ glxgears
6942 frames in 5.0 seconds = 1388.316 FPS
7225 frames in 5.0 seconds = 1444.939 FPS
6122 frames in 5.0 seconds = 1220.387 FPS
5284 frames in 5.0 seconds = 1056.730 FPS

Mmmm... I have also falls of fps, but 8-20 fps is too slow...

Try to install nvidia-glx-envy driver, maybe it could be a version problem.

Bye!

I am using nvidia-glx-envy. Seems like game problem, probably. I will try other game.

I have the same expirience with nexus.
May be reason is that I have installed kubuntu as hardy heron when it was beta and then just updated it? I don't want to reinstall kubuntu. How can I find out what is the problem with games (and not only) in my system?

May be old version of nvidia drivers should be better?

Hi,
I experienced having low fps in various games in Ubuntu eg. ETQW, UrbanTerror etc. and I thought I had a graphic card issue! I own an AMD Athlon 2500+ CPU, a Radeon HD2600pro AGP GPU (512Mb)and have 1gig of RAM. In the beginning this system lagged in all my games and I started playing with xorg.conf and did all the GPU related tweaking that I could come up with.. to no avail!
I noticed that that ETQW only used 128Mb of my GPS vRam (fix: ./etqw +set sys_VideoRam 512). This didn't give me higher fps but allowed me to get a better resolution (yay!!). After some tweaking I decided to try something different. I clocked my CPU from 2500+@3200+ setting FSB=200mHz, multiplier=11x and vCore=1.7. This dramatically improved my gaming experience and glxgears gives ~4000fps vs ~3500fps before the clock! So my conclusion is that I didn't have a GPU problem after all.. but rather my CPU was the bottleneck... Your specs are pretty close to mine but I think your Celeron CPU is your main problem.. I don't know this for a fact but thats my guess!

My system:

X@X:~$ cat /proc/cpuinfo

Your problem....you own AMD graphics cards.


Your solution.... get NVIDIA. :)

:) ... Yeah I get that allot, but replacing my ATI card with eg. a Nvidia 8500GT gives me about the same performance in ETQW on my system. (ioUT however seems to be more sensitive to GPU brand). Actually it is my personal opinion that ATI cards are not too bad.. That said, the main purpose of my PC is not gaming, but presentations and video playback which ATI is better suited for..

I Haven't been able to find any faithful benchmarks that actually compare these to cards so you'll have to take my word for it (or test it yourself)

There is nothing wrong with AMD/ATI. I have integrated ATI graphics and get 92FPS with Compiz on and 99FPS with Compiz off (that's with the FPS limiter on).
I'm also using the 2.6.24-21-generic kernel. It seems to work a lot better with ATI cards.
