Help with RDR2 install.

[DumbledoreCalrissian]

RDR2 install spits out a 'Social Club failed to initialise graphics: code 18' error.
Multiple online forum posts point to adding a launch option (in steam) - "WINEDLLOVERRIDES=vulkan-1=n,b %command%" to fix the error.
How do I do this in Heroic?
I saw a Reddit post that pointed to an 'advanced options' where I can enter this. But this seems to be for an older version.
Linux noob here.
Thanks for your help!

I found it!
I added an environment variable like this -
Variable Name : WINEDLLOVERRIDES
Value: vulkan-1=n,b

I know the post is old, but I have a question. Do you have your game installed on Steam deck internal storage or SD card?

[DumbledoreCalrissian]

I'm not on the Steam Deck. I have on Lenovo Legion laptop. Why do you ask?

[JSwierk]

Oh sorry, made a mistake.

Sorry, complete Linux noob here. How and where do you add that variable?

Hi I wasn't having any luck with Elden Ring using ModEngine2

In lutris I set DLL overrides to

WINEDLLOVERRIDES="dinput8=n,b"

I tried

Variable Name : WINEDLLOVERRIDES
Value:dinput8=n.b

Already works great with Lutris, but I'm trying to learn Heroic Game Launcher that has some nice features, but is also hit and miss in some areas.
