Choppy FPS, Jumpy Controls

(node357) #1

Hi. Haven’t been able to run ETQW properly since I bought it. Tried running it on various distributions, with 2 different NVIDIA graphics cards, 2 different sound cards, with and without crappy pulse audio. The frame rate jumps around like crazy no matter what timing method I use or whether vsync is on or not, even at lowest graphics settings, and drops below 30 FPS constantly. When this happens, the mouse gets jumpy and the sensitivity is totally inconsistent, not to mention it’s hard to keep track of what’s going on visually. I had similar problems with Doom 3 and Quake 4. Other games like UT2004, Penumbra series, Open Arena and Nexuiz run fine. How can I make ETQW run decently?

Try playing around with this console command:
r_useThreadedRenderer
Try setting it to 0 if it’s 1, and 1 if it’s 0.
See if that helps. Might, might not.

Thanks. Tried that, and the game said threaded rendering isn’t supported in the build. Great…

You need to start the game with the etqw_rthread executable to make use of threaded rendering.

I’ve tried both the threaded and non-threaded executables with the same results.

System specs?

And post kernel config.

Edit: Try turning off sound (s_noSound 1; s_restart) too

I switched to Linux this weekend because the game keeps crashing under XP for some stupid reason. The frame rate is okay under Linux (Ubuntu 10.04) but I have the same problem, it feels choppy. I get 90-95 FPS when I run a timedemo and it was slightly higher under XP (around 110 FPS) but that difference is not big enough to account for the choppiness in my opinion.

Any help would be appreciated.

I decided to to take a deep breath and make an attempt at compiling my own kernel in the hope that it would improve performance under Linux and reduce the choppiness.

I have no experience at all with that, so I searched for forum threads and HOWTOs and happened to stumble onto this: KernelCheck. Here’s the link to the corresponding page on the Ubuntu forums.

Warning: do not use this program if you aren’t prepared to reinstall Ubuntu and make sure you have a backup of all the important stuff when you decide to try it out!

That said, I found it pretty easy to use and it actually works! At least for me :slight_smile: . I compiled my own kernel with the most recent stable built and the default settings provided by the program. That gave me an extra 5-10 FPS but more importantly, it removed most of the choppiness for me.

This turned out to be a lot easier then I expected and I’m happy with the results. I’ll experiment a bit more with this.

This thread, and more specifically this package, is probably what you’re looking for. It could be because I have it installed on a laptop, but it seems the low latency options aren’t enabled on 10.04.
