[Linux] Having short freezes during game

[Samega7Cattac]

Your system information

• System information from steam
• Have you checked for system updates?: Yes
• Are you using the latest stable video driver available for your system? Yes
• Have you verified the game files?: No

Please describe your issue in as much detail as possible:

Having short freezes (from 3 to 5 secs duration) during game and then gets back to normal, but quite often. During that time one of the CPU cores was at 100% and the frametime spike.
The system is still responsive.
Mouse control still works.

Steps for reproducing this issue:

1. Playing a normal match.

Screenshot

FPS is capped to 60 and normally is always around there.
Normal frametime is 16.5ms (it's normal a bit of inconsistent against bots but not 30ms)
(ignore the GPU usage)

Hello @Samega7Cattac, this reads like the video driver is compiling shaders for the game as they are needed. If that is true, then you should be able to go to Steam -> Settings -> Shader Pre-Caching and enable both Enable Shader Pre-Caching and Allow background processing of Vulkan shaders to mitigate this.

Expect that the first run and after video driver updates to take a fair amount of time, and pre-caching updates should be relatively quick.

I have both enabled since always but still

There's a drop in my GPU usage, no usefull info on dmesg.
On dota console: [Entity System] ExecuteQueuedCreation() took 1180us [ Spawned: 1, Activated 1, PostDataUpdate: 0, Destroyed: 0, Deallocated: 0, PvsUpdate: 0 ] (idk if related)
No unusual usage in disk, memory or disk cache

Having same issue

Probably thats not related to Linux but all the OSes

[Samega7Cattac]

Maybe related to this fossilize issue, since it's an issue I have related to shaders, rn using the workaround (RADV_DEBUG=nomemorycache) and uncap the fps seems to help but still happens.

[Samega7Cattac]

The fossilize issue was solved but the freezes still happen, more often since last update making it literally unplayable

@Mayurifag what OS ur using?

[Mayurifag]

@Samega7Cattac I have ArchLinux with all required latest packages. I have i7-8565U / 16GB RAM / SSD / no discrete videocard setup

in my situation it doesnt seem to be related for the issue you have mentioned, but still thanks for information 😄

GPU usage have a dump every time it happens:

and on CPU one of the cores goes to 100% and the other also have a dump:

[Samega7Cattac]

System was too unstable so switched to another tty
Idk if it's normal for dota to be using +2Gb of ram and ~60% of my CPU just on post-game screen too(same thing on main menu)

@kisak-valve it's been 3 months already, if u need any more info just ask.

[Samega7Cattac]

got a new SSD and moved the game to there, since then I didn't have this issue so I will close this for the time being
