No DLSS option for games in heroic launcher (self.linux_gaming)

All my steam games that support dlss work with it, but my games using the heroic games launcher don't even show the option for DLSS in the game menu. I tried researching it but didn't have too much luck with finding a solution. I found one post saying that proton uses dlss by default, I'm using proton experimental but it still doesn't show up.

Heroic launcher is nice but I have had such a hard time enabling features like dlss and mangohud on it.

I'm using Linux mint 22.1.

EDIT: I fixed the issue. There is an option in heroic called "auto install/update DXVK-NVAPI on prefix" I had to enable it in the global settings and on the specific game. DLSS works now with frame gen.

I still have yet to get mangohud working with heroic tho

EDIT 2: I got mangohud to work with heroic. I had to use version 23.08

There's a number of things in the mix as to why this may be, but you pretty much need the bleeding edge of everything: latest Nvidia drivers, VKD3D, proton experimental...etc. I can't even think up the exact combo right now, but start digging there.

I edited my post with the fix. Thanks for the help

If you're using the flatpak version of heroic, try installing mangohud flatpak 23.08. There's a github issue on heroic that the latest version wasn't working and that seems to be the work around.

I stumbled on a reddit post that suggested the same thing and it did work for me. Thanks for the help!

I'll try that version of MangoHud too. It has never worked for me

Lmk if it doesn't work. I can try and give you some other tips that might work

not sure how heroic works but try adding PROTON_ENABLE_NVAPI=1 as a launch/environment variable

I edited my post with the solution. There was a setting I had to enable globally and per game to enable dlss. Thanks for the help
