Dota is nearly unplayable starting around 15min gameplay and getting worse the longer its played:

Dota is eating up CPU and Memory (CPU Load is 99,5% of the Cores that Dota uses)
I have no solution so far, it may be related to steamwebhelper. What helps is to stop Dota or kill the dota Processes and start over.

This is reproducible I already contacted the support but this was not much helpful.
Update:
Support suggested to play in slowest resolution that would be 640x480 :-).
The lowest graphics settings is not helping at all.

It Starts around 10-15min playtime sometimes earlier sometimes maybe a little later but after 20min latest. The game stutters then, Load is high and its hard to play and target objects cause I might miss a unit cause of the "stuttering"espc. in fights.

Since other games just run fine for hours its solely a Dota2 Problem and no
"General Computer Performance Problem" also there are no other applications open, only "Steam and Dota"

I didnt do any major software updates before the Problem showed first, it came with one of the latest Dota2 Updates and persists since then.

I suspect it could be a memory leak or other "Condition that gets worse over play time"
-> Programming Error of a kind?.

Is any of you experiencing similiar Performance "Process/Memory Leak" issues and
maybe got a solution for it?

Thanks in Advance for any Hints.

I think we all know that this game sux, development wise. You have a powerful machine and prove it still can't run it properly. I can run sc2 perfectly and play on the US east or even west server from aus and get no ping whatsoever. If I play sea or anywhere else 90 plus ping. even the servers suck.

Kernel 6.5 is end-of-life for almost 6 months. You should use a supported kernel from your distro.

Sorry guy its a supported kernel in my distro and its definitly not part of the problem.
Some Distros like Debian have much older kernels and they run fine too with all other games.

Part of the problem is that the devs dont focus on quality, and break the game on a reugular basis.
Since this is the 10+ time i got "issues" solely with dota2 and no fu**ing other game out of my games running on the same "stable Hardware" and "Software Platform"
So Valve should just start to do their freaking job and focus on S T A B I L I T Y
then on featuritis that breaks the game so many times.

agreed

Dota could really need a spring cleaning and optimization patch

[matze77]

Update i stopwatched this:
21:23 (killed it then) then again around 26min

The "lagging graphical effect" then persists after the game is over in Main Menu where you can watch the "Movement of your hero/avatar" these "Animations" are not fluent they are micro stuttering then or missing frames.

Ingame there are like missing some frames and its "graphical jumpy" meaning your hero is not (anymore) there where you last seen it.
The interface is not smooth anymore and its hard to control.

I tried another Kernel (switched back to 5.15, 6.2. ) tried Nvidia Driver Versions: 5.15, 5.30. 5.35 all, i even switched to xfce from cinnamon all to no effect.
As mentioned before when you "tab out" of Dota the system "outside" is perfectly fluent.

Any help appreciated alot.
