In light of finally installing Ubuntu 10.04, I decided that 2010 seems like a good year to ask:

Does compiz make UrT unplayable for you all as well? I'm not talking framerates. I'm still getting great framerates (well above 125), and the drop due to compiz is only really seen on intel and Nvidia cards:

I'm talking about this random slow-motion style jittering that plagues me when I play while compiz is on. When off, Urt on 10.04 (the optimized binary, not FrozenSand's) runs great. Anyone else getting this? Anyone not getting this?

Its pretty silly to have to disable visual effects to play a game... (I understand the technical challenges, but it doesn't make it any less silly).

My system:

Ubuntu 10.04 fresh install with Compiz
Phenom II x4 955
Asus 790X Mobo
4GiB G.Skill ram
Nvidia GTX260 core 216
etc.

It's a known problem compiz and pulse audio, too.
you can check out the page from ioQuake3-team.

Hey I’m running Ubuntu or some other distribution with compiz and ioquake3 is all screwed up?

Disable Compiz.

Why is my audio crackling / distorted under Linux?

This is the result of using the Pulseaudio sound server. This soundserver is enabled by default in Ubuntu Hardy and Fedora Core 9. It may be enabled on other distros. Pulseaudio allows you to control the volume on a per-application basis, but it appears to have some serious bugs and is listed on the official website as under ‘heavy development’.
To see if you have Pulseaudio running, use the following command:
ps -A |grep pulseaudio
If it’s running, I recommend you search for the proper way to disable it for your distro. Some hints: Gnome needs to have it turned off in the System-> Preferences->Sound control panel, and you should remember to clear any references of it from /etc/asound.rc, ~/.asoundrc and ~/.openalrc.

As I'm using PulseAudio and not having any problems, I was wondering more if this was the same problem other people were having (ie lag not drop in framerate), or if there were people with similar setups using Compiz and not having problems.

I know you can just disable Compiz (compiz-switch is pretty useful), but I'm wondering if there is resolution in sight or if there are other configurations that can play with compiz.

Check the 'Unredirect Fullscreen Windows' in CompizConfig Settings Manager. That's what I do and I don't have to swtich to Metacity when playing.

Of course, if you're not playing fullscreen, this will not help.

If that's true they must make it the default, immediately.

I had the same problem, the FPS wasn't the problem, it just felt more laggy with compiz on. Besides that, when I put AA and AF on a high setting in my nVidia control panel, the AA was also applied to compiz, which made stuff even more laggy (I had to use the "override application settings", because else ioQ3 wouldn't accept it somehow).
So as a solution I made this launcher script:

metacity --replace &
sleep 1
nvidia-settings --load-config-only --config=/home/thomas/.nvidia-fullaa
mumble-overlay /home/thomas/games/UrbanTerror/ioq3-urt
nvidia-settings --load-config-only --config=/home/thomas/.nvidia-noaa
compiz --replace &

It turns Compiz off and loads the full AA/AF settings with the nvidia-settings tool.
Then when you quit UrT, it restores the AA/AF settings and launcher Compiz again :)

As a result I can play very smooth with full AA/AF settings, while Compiz also runs smooth when not gaming :)

I thought I'd post it since so many people are having problems :)
Also, I've never had any problems with Pulseaudio since 9.10, it runs great here and I can finally play UrT, use mumble, and skype at the same time.


EDIT: Wow, thanks SailorMon! Using that option there is indeed no need to disable Compiz :D Now my script is just three lines:

nvidia-settings --load-config-only --config=/home/thomas/.nvidia-fullaa
mumble-overlay /home/thomas/games/UrbanTerror/ioq3-urt
nvidia-settings --load-config-only --config=/home/thomas/.nvidia-noaa

Hi, can you explain how to lunch this script or where to put it and what exactly do it?

i'm very interesting.

Thanks a lot!

(sry for my poor english)

Try like this:

Create a file containing something like this:

#!/bin/sh

nvidia-settings --load-config-only --config=/home/thomas/.nvidia-fullaa
mumble-overlay /home/thomas/games/UrbanTerror/ioq3-urt
nvidia-settings --load-config-only --config=/home/thomas/.nvidia-noaa

/home/thomas/games/UrbanTerror/ioq3-urt is the UrT executable, so you need to adjust the path to suit your location. I'll keep itMumble in the current form for this example, but I hope you know how where the actual location is.
Second, the location of the config files needs to be changed, too. You know where the configs are.
Third, if you don't need Mumble (google it, if you don't know what the program does), edit this line

mumble-overlay /home/thomas/games/UrbanTerror/ioq3-urt

to

/home/thomas/games/UrbanTerror/ioq3-urt

Save the file as "urt_aa", open a console, navigate to where the file is, and type

chmod +x urt_aa

Now you're done. Do

./urt_aa

every time you want to play the game (don't use the ioq3-urt file directly).

If you go with the file browser from KDE/GNOME/XFCE etc., you can also double-click it. I hope it's clear enough (I'm used to working in consoles).

Edit: spelling

Thank you so much... but, i need to know what is ".nvidia-fullaa" and ".nvidia-noaa".

Where can i get it?

There are not present in my home...

[pr0fan0]

Ok guy, probably i've understood.

I run nvidia-settings, and i've modified Antialiasing Settings.

1) I've tested with FULL AA in "Override Application Settings" mode. -> FPS = 60-70
2) 4x AA in the same mode. -> FPS = 100-110
3) 2x AA in the same mode. -> FPS = 125

Urt results playable only with the 3° setting.

But... in all these cases, urt is worst than whitout compiz.
Whitout compiz urt motion results more fluid.

with 2x AA, FPS are still 125-126, but the refresh appears too slow or something like that.


Anyway Thanks a lot, and i attend for any help.

(sry if something results nonsensical :P i've to improve my english ihihih)


edit:

i've checked Texture Sharpening, and urt appears get better
