Hello @Shaaah, from your system information, it looks like you're using AMDVLK. Can you test if the game behaves the same with mesa/RADV?

Hi, @kisak-valve! I got no problem when I start Dota 2 with mesa/RADV. Thanks for the help :)

Do you have vulkan memory leak? After playing one match my system eat 6GB ram with only steam and dota. If i exit from steam and dota my system eating 3GB ram, no other program runing in background (btw, on cold boot my system eat 800-900MB ram, debian xfce). And i cant find in xfce taskmgr what process eat 3GB ram. If i play more matches my system eat all 8GB ram and pc crash, only hard reset help.

I get this exact problem (src/tcmalloc.cc:390) but I am not using AMDVLK. In fact I uninstalled it just in case the env variables people mention do not properly force steam to ignore it (VK_ICD_FILENAMES).

Here is my system information.

I prefer steam-native but have tried with the self-contained runtime as well. It does work if I symlink in my system /usr/lib/libtcmalloc_minimal.so to a relevant Steam folder which is what I have been doing for the past 2-3 months, but demoing heroes in Dota crashes the game and I am wondering if this is somehow related.
