At the moment when you launch Ratchet And Clank Rift Apart on the ROG Ally you will be prompted with a message indicating your graphic drivers are out of date. The issue is, the recommended drivers are not currently available for the ROG Ally.
Crashes are a common issue currently.
I will update this guide when or if we get updated drivers.
At 1080p with FSR I managed to get an average of 30-45fps with the lows occurring during intensive gameplay sections with multiple enemies on the screen at once and during rifts between dimensions. I tried to find a balance between stable FPS and nice visuals but it’s tough. Upping the graphical settings got me more dips in 20 fps when a lot of things happened on the screen at once especially as you get further into the game.
At 720p upscaled to 1080p using AMD RSR and the same graphic settings it gave me a higher average of FPS making it a smoother experience overall with higher highs and lows but still suffers from performance issues like sluggish FPS when purchasing and upgrading weapons.
