My Windows friends (cough!) were raving about this - and Digital Foundry had a video about it, too - so I got interested myself. It was nice to see Linux support even if the use cases are more niche than on Windows.

That's said, testing out the app myself, I just had good luck using this with Star Wars Jedi Fallen Order installed on Heroic. Was stuttering up the butt and it's gone with the compile. Haven't tried it on other games yet.
