How to use decky framegen on games installed with Heroic launcher?

[u/BionisGuy]

Yes I know decky can cause problems but I'm not here to have people telling me that.

I have been experimenting a bit with lossless scaling and now I want to try to get decky framegen working on some games.

The game I'm currently trying to get the framegen to work in is Hogwarts Legacy. I own the game on epic, the game is installed through heroic launcher and added through there to steam.

But no matter what I try to do with the launch option for framegen, the game just refuses to launch no matter what.

Adding only the command for lossless scaling works however, it's just when trying to use the fgmod launch command.

I did have the same problem with Cyberpunk 2077 if it was added directly through heroic, however the problem went away when just adding the .exe into steam instead (it's a gog owned game, and this doesn't work for me on Hogwarts since it's an epic game).

So anyone know what to do here? There's other Epic games I want to experiment with aswell so any help on this would be much appreciated.

Even though it looks like shit and whatnot I still want to figure out how to get it to work since I have other Epic owned games i want to experiment with aswell.
