Tip: UT2004 crashiness

tactless · Posted: Wed Mar 31, 2004 12:06 pm Post subject: Tip: UT2004 crashiness

Since most (if not all) of UT2004's buginess is in the Karma physics library (some kind of memory allocation problem there), setting physics detail to "Low" helps. This apparently disables the ragdoll physics model, and seems to have little or no effect on gameplay.
Furthermore, Karma physics seem to be what makes UT2K so CPU-intensive. Lowering the detail gave me a nice performance boost on my Athlon XP 2600 / GeForce FX 5700 Ultra.

Good tip. I'll give this a try tonight. Although I'll miss the spectacular death animations if I do this, being able to play for extended times is a good trade-off, no?

i played for about an hour to try it and i had no crashes.
i don't need the nice karma animations and it does indeed
help a bit with a lot of players on a server, though i still
only get about 15-20fps when a server has 16+ people
on it.

well, i just want to let the community know that i'm playing 3-4 hours strait without any crashes our breaks with the maximum details.
i just did 2 things:
-> use the openal.so and libSDL from my system (not the provided ones)
-> and found some binaries that solved the crashes problem (here's the link: https://bugzilla.icculus.org/show_bug.cgi?id=1413)

don't know if this can help you, but i hope so.

--------------------------------------------------------------------
AMD 2000+
GeForce FX 5200
gentoo-dev-source 2.6.3
openal 20040303
libsdl 1.2.7
nvidia-kernel and nvidia-glx 1.0.5336-r1

Bad news... still experiencing crashed on ONS online (specific server though). Same KFarfield assertion thingie. I have replaced openal and libsdl with symlinks to my own, but haven't tried the alternate binaries (I've heard they make things worse). Can't wait for a patch on this...

in my case it made things better. there's any problem on trying the new binaries, if they make things worse in your case, just replace them to the old ones (backup them first of course).
in my box, just with openal and libsdl linked to the ones of my system, the game crashed too.

Well, replaced binaries, libSDL and openal linked, physics low, crashiness very low but still there (KFarfield). Looks like icculus is working on it though.
I sure hope this doesn't happen with other anticipitated Linux releases (read: Doom III, even though id did a great job on Q3A).

the crashes remain here as well, though
it seems they occur less frequent.

Ryan C. Gordon has released another bugfix.

It should fix the crashbug, but I haven't tested it, yet.

http://icculus.org/~icculus/tmp/ut2004-kintersect-fix-x86.tar.bz2

If you experience problems with the new binaries reply to https://bugzilla.icculus.org/show_bug.cgi?id=1413 please :wink:

Just a quick question:

when you guys speak of crashes, what exactly do you mean? Does the game just terminate?

The problem I'm having (and I had it with UT2003, too) ist that every so often, I just get a few huge triangles that meet in the centre of my screen. Makes it unplayable, of course, but when I press escape, the menu is fine.

Will the patch mentioned above help me here? It seems more like a graphics engine problem than a physics engine problem to me, so maybe not.

Thanks,
mollmerx

I get occasional crashes, but the more annoying problem, is after I've run the game a few times (and exited or crashed) it won't load again until I reboot. Weird errors appear, about a LinuxManager.h.

All this constant rebooting makes me feel like I'm running Windows

I just changed to the patched executable mentioned in this thread, and also have relinked the openAL and libSDL libraries they used to mine. I'm a little confused - why ask to install the libraries if they're going to install them anyway? I said no in the installer.

Crashed 6 times in one game last night. Installed those new binaries from this thread and it hasn't crashed since.

Yah, tried that. Not playing the game atm, as my mouse likes to die occasionally, now that I have agame worthy of playing and some time to play. Also I am trying to compile opeoffice-ximian with little success.

So that's all the CPU power gone atm. When it happens again I'll post the error exactly.
