In your steam library you can set launch options for every game by right-clicking on it -> properties. There you can use the heapsize command to limit the cache to the game. It really helped me for rust since it was slowing my pc down. Here is what you have to type in:


1 GB Cache: -heapsize 1048576
2 GB Cache: -heapsize 2097152
8 GB Cache -heapsize 8000000(< This is what I am using)

Give it a try then report back.

Edit: If you have overall ram issues you might also want to try to enable ram clearing in-game by console by entering:

gc.collect (activates garbage collector which throws out unused stuff out of your ram)

gc.intervall 180 (automates the gc.collect command to be used every 3 minutes)

Just crashed my pc for the first time ever (as in it's never crashed before)
Clean new download, I was gonna check out the game after a very long time
Froze my PC and after awhile it blue screened and restarted with issues on alot of other software from the abrupt cut off

What did they do to the game??
Only played yesterday but it takes a full YT video to finally load in
It used to be seconds. Oh n I put my GFX settings to lowest since yesterday which was my first day back

-MaxMem=30000

So when joining a server it loads assets all over everytime?
I know it loads from a seed, but is there a option to save that after loading it once instead of reloading from scratch everytime?

I see a checkbox for "Use Cache" in server listing but idk what that does or if it does anything
Also, just about nothing shows up when looking it up. Just an update that says "We've added this button" (basically)

Tried this n doesnt work
I put it to 6, 7, and 8 GB. But still goes over
Is that the correct one? Does capitalization matter?

I have 16 total and it shouldnt need more than 8
Once in-game it stays below 6 even before I added maxmem

EDIT: According to Steams own support page on launch options:
https://help.steampowered.com/en/faqs/view/7D01-D2DD-D75E-2955
The commands only work on "GoldSrc and Source engine games only"
