Helldivers 2 runs pretty good on the new DroidDeck app
Sorry about the poor quality video, I had to record using my phone in one hand. Kinda prefer this to ArmadaOS because of the access to clustertune and fan curves etc. Running at 720p ,steam deck preset, performance resolution scaling, light clustertune underclock and max 80% fan speed. I had to use the bannerlator proton (arm64) compatibility option to get it running. Way easier than gamenative etc, I was never able to get this to run at all with those.
