This is helpful thank you

#

loading save also fixed my map apparently
those three are when i'd tried

#

when i kept ctrl+clicking and nothing was happening, apparently it was

forest sail Jan 14, 2026, 4:15 AM

#

Go to Vein/Saved/Config, open or create Engine.ini, add

[ConsoleVariables]
r.Vulkan.Bindless.MaxResourceUniformTexelBufferCount=262144

Try that

grim cosmos Jan 14, 2026, 4:17 AM

#

this is under the Windows Engine.ini

#

considering im on proton
that correct?

forest sail Jan 14, 2026, 4:17 AM

#

I don't know what I'm looking at

grim cosmos Jan 14, 2026, 4:17 AM

#

oh i couldnt find that line

#

so i need to add it into Engine.ini

#

which one

forest sail Jan 14, 2026, 4:18 AM

#

Oh no put that at the bottom of Engine.ini

grim cosmos Jan 14, 2026, 4:18 AM

#

copy that

#

So, under /Config I have Windows, Linux and CrashReportClient

am I adding directly into /Config/Engine.ini or am I adding a file named Engine.ini at the root of /Config ?

#

grim cosmos Jan 14, 2026, 4:24 AM

#

forest sail Go to `Vein/Saved/Config`, open or create `Engine.ini`, add ```ini [ConsoleVaria...

launching with those now in the Windows/Engine.ini

forest sail Jan 14, 2026, 4:24 AM

#

Either Windows or Linux, sorry

#

I'm not sure which one is used in your setup

#

Probably Windows through proton

grim cosmos Jan 14, 2026, 4:25 AM

#

i didnt know both existed in the same install

#

was why i was wondering 🙂

#

i added it to Engine.ini
can switch back and forth

#

snappy too

#

lemme load and try now

#

ok thought it might have crashed there but it took forever to turn it off while in game
gonna turn it back on

#

i wanna say about 30s ?

#

FPS showed as about 2 then creeped back up to 40-50

forest sail Jan 14, 2026, 4:34 AM

#

Same crash?

forest sail Jan 14, 2026, 4:34 AM

#

grim cosmos i didnt know both existed in the same install

They do not

grim cosmos Jan 14, 2026, 4:44 AM

#

forest sail Same crash?

No it recovered

grim cosmos Jan 14, 2026, 4:44 AM

#

forest sail Same crash?

sry for tag

#

this file shows two files

#

from the game path

#

does switching between proton and scout linux retain the files between my installs...that doesnt sound right

#

if so, could be an issue?

forest adder Jan 14, 2026, 4:45 AM

#

the engine's only gonna use one of those

forest sail Jan 14, 2026, 4:45 AM

#

It does but no they will use separate inis

grim cosmos Jan 14, 2026, 4:45 AM

#

kk

#

ok so its normal for it to show as two files in the same game paths

#

makes sense to me

#

just confirming

#

ok ill say this one is fixed temp but ill play for a bit and share in here if i get another similar crash
ty for the quick help

#

performance looks to be about what i had before
i am alt-tabbed
fullscreen
seems fine so far
