[Linux] Watching demos crashes to desktop during second half

[rage311]

I've tried watching several demos from ESL One, and they all crash a few rounds into the second half. The audio starts to stutter a little bit (repeating the same ~0.5s clip a few times before continuing), then the game just crashes out without warning. I've watched several of these demos under WINE on the same machine and they work just fine. I monitored my RAM and CPU usage before the crash, and although the RAM usage for the game steadily creeps up (ended around 3.1GB reserved), I still had about 1.8GB left in the system to allocate. The CPU usage had a few spikes on a single thread when the audio stuttered, but the cores weren't ever ALL pegged at 100% or anything.

I have all of the game settings maxed out, and the game runs just fine for hours without a crash, but I can't get all of the way through a single demo without a crash. Maybe I should try watching a demo with multicore rendering disabled, just to see... the issue is that it takes ~30 minutes to get to the point in the demo where it crashes, so it takes a bit of time to try different settings and see if they affect it.

My system information is below. Please let me know if there's any additional information that I can provide to help get this resolved. Thanks.

Although I'm running awesome WM currently, I've also tried this under KDE 4.14 with the same results.

Disabling multicore rendering does indeed fix it for me. I've successfully watched two ESL One demos to completion without changing anything else.

I lied... disabling multicore rendering didn't permanently fix it, it just changed when it happened. I'm now sure that it's an Nvidia driver issue, but for some reason, CS GO was the only game that had been triggering it. I've since done some GPU stress testing with several instances of gputest and that eventually caused the same crashing/freezing issue. I've posted some more details on Nvidia's devtalk forums for my particular issue, and it sounds like other Nvidia users are experiencing something similar. This was referenced in issue #269.

Here's the Nvidia forum thread link: https://devtalk.nvidia.com/default/topic/813720/linux/gtx970-346-35-amp-346-47-linux-mint-17-1-steam-csgo-segfaults-during-play-crash-the-game/

If anybody has a similar issue, please contribute any details you can so that we can get a fix in for the driver and play CS without crashing!

Thanks for linking the #269 and also for adding to the nvidia devtalk post. I will attempt to recreate my issues using gpu stress tests , as you did, and post back with the results on the nvidia devtalk thread.

Closing since if this is still occurring since the 64 bit client update, then the issue needs to be re-profiled. If anyone is still encountering this issue, please open a new issue report.
