Choppy gameplay and audio in Wolfenstein: Enemy Territory


Hello, all...

I am trying to get Wolf:ET running satisfactorily on my laptop. On the desktop, it runs great, no problems whatsoever; but on the laptop, only occasionally is it actually playable. Most times, audio is VERY choppy, often with laggy graphics, and it's particularly bad on those craptastic "mod" servers that have custom "cutesy" audio clips and maps in them. The number of players in the server does not seem to have much effect, if any at all.

I've been doing a lot of research on this problem, and all I can find are references to network settings (e.g., making sure I'm set in the configs to use "LAN/Cable/DSL" as my network, or running '/rate 25000' in the command console in-game, etc.). These settings make no difference. I've also tried running my graphics settings at fastest possible, dragging resolution down to 640x480, with 16-bit color and textures, and dropping audio samples down to 11 kHz. Still no joy.

My desktop machine, which has no problems, has the following specs:
Debian Etch/Lenny blend (mostly Lenny), AMD64 variety.
AMD Athlon64 3000+, running at factory spec 2.0 GHz. 4003.35 bogoMIPS.
2.0 GB RAM (I don't recall the speed though)
nVidia nForce3 onboard audio
nVidia GeForce2 Ti AGP video card with IIRC 64 MB video RAM
Atheros based 54Mbps wireless using madWiFi driver set and a fair to good connection.

My Laptop machine, which has the lagginess problems, has the following:
Debian Etch/Lenny blend (again, mostly Lenny), AMD64 variety
Intel Core2 Duo T5250 (1.5 GHz, registers as 2 separate CPUs, running speed government that automatically goes between 1.0 and 1.5 GHz -- I wonder if this could be it...) - 2992.46 and 2992.35 BogoMIPS respectively
1.5 GB RAM
RealTek onboard (being a laptop) audio
Intel GM965 Mobile video (with working, native OpenGL - glxgears framerate in the 4200 to 4300 fps range) and no clue how much vidRAM -- how to tell?
And finally, Intel Pro Wireless 3945 54 Mbps Wifi with good to excellent connection running the iwl3945 driver.



So the machines are comparable in most ways, the main differences that would affect gameplay being the video and the processor. They're running almost identical loads of Debian with the same libs, etc., so that shouldn't be the issue.




Any thoughts?



Thanks in Advance!

Edit: The CPUFreq governor is not the issue here. Setting it to manual (userspace) 1.5 GHz for both CPUs did not solve the problem. I had joined a server that had only 4 other players, followed one of them, and the choppy audio and game lag started. It seemed okay until I followed a player, but I did not actually join a team myself...

Still puzzled by this one...

Intel GM965 Mobile video - not really a grafix card, glxgears testes basic OpenGL capabilities ( no texture compressing, shaders , etc..)
I sppose you could drop all possible effects via autoexec.cfg and run it in 600x400

Thanks! I found that same page you linked and haven't had a chance to try it yet.

I did try in the in-game settings to drop everything to minimums, including resolution, but nothing helped. I realize that a laptop's not likely to have a decent video card, but I was hopeful there for a bit. Well, we live with what we're given or can afford to buy, right?

Still, having read online, this game appears to be several years old (I was surprised) and requires something on the order of 1/3 the specs I have. I expected the CPU to be able to compensate for some stuff the GPU can't handle, and the machine's new enough I figured it could handle anything from before ca. 2005. Well, I've been wrong before!

I'll try the suggestions in the link when I get the chance.



Thanks again!

CJ
