[Linux] Constant lag spikes

kmg

I dual-boot win7 and Ubuntu, and I just started trying out the linux build. I just installed it directly from Steam. I've tried a few DEs, and I'm running Nvidia 331.13. For some reason I seem to get constant lag spikes only on linux, no matter what server. Has anybody else experienced this? I basically just start rubber-banding like crazy, as if the server were lagging, but I'm the only one affected. My ping bounces up to around 300. This usually lasts for a couple minutes, can settle down for a few seconds, and starts up again.

nope, havent noticed anything like this. Try some older drivers, like 319.

I recommend this ppa for nvidia drivers:

They havent added anything above 319 yet.

Edit: Another PPA i remember to have used earlier have newer versions as well:

A few random questions:

Is this net lag or game lag? Is your frame rate low? do you have big spiky bits if you run profile? what does your r_stats look like? can you post a log? is that enough questions to seem legit?

My FPS is usually around 80, never gets below 60. It's definitely net lag, as I do red plug and my ping in the list goes from 60-80 to 200-400 while this is happening. I'll try out some older drivers and try and get you o log in a bit.

Attached a log file. There's no spiking when profiling, and it doesn't seem to be affected by the lag at all. r_stats looks totally fine as far as I can tell. It certainly doesn't complain about waiting, and all the memory numbers look fine.

Edit:
Can't attach things apparently. Awesome.

good deal, I will take a look at the plog see if there is anything we can track down there


Also of interest might be net_stats
