Running the game from the default install (either installed here or moved here from another location) path works fine. Moving the game or installing it on a custom directory does not.
I run the flatpack version of hgl and everything is set up correctly. Other games work using the same custom parent folder. I also have my steam games on the same partition.
So, I press play in hgl and the redlauncher runs. From there I press play and hgl shows "playing". I get no image and no witcher 3 application or process is running according to system monitor.
Any help is much appreciated.
