ASUS ROG Ally Optimized Settings
In Midgard, you can crank up the resolution to 1080p, set most settings to High or Ultra and FSR to Quality, and get zero sub-30 FPS drops, but that won't cut it in Svartalfheim. Just note that you ought to increase VRAM allocation to 6 GB if you plan to play the game with Medium or higher texture quality to avoid traversal stutters that can take place with 4 GB of VRAM.
For an optimal experience in Realms other than Midgard, we recommend the settings combo on the screenshot above, coupled with 900p resolution and 30 W TDP. In other words, we recommend playing God of War Ragnarök while hooked to a charger. Those couple of extra frames at 30 W don't matter much in most other games, but here, they really do improve the overall experience. With these settings, you can expect mostly stable 30 FPS performance with an occasional drop into the high 20s here and there, but nothing serious enough to hamper your gameplay experience.
The ROG Ally's performance varies wildly, but we didn't mind it because the VRR screen, in combination with low frame rate compensation, makes the experience great, without subjective stuttering even when the frame rate drops from 60 to 30 in an instant. That said, you can use the built-in frame limiter or RTSS to lock the frame rate to 30.
If you'd like almost zero sub-30 FPS drops, set FSR to Balanced or Performance. That said, similarly to Steam Deck, the image quality takes too big a hit with FSR set to Performance for us to recommend anything below FSR Balanced.
All you battery hoarders can drop the resolution to 720p, turn off any upscaling or use FSR Quality, set everything aside from textures and Anisotropic Filtering to Low, and set TDP to 18 W to get about 30 frames per second with almost zero drops below the high 20s, which results in a battery life of about an hour and a half.
As said in the Steam Deck optimized settings section, FSR frame generation does not feel great at low frame rates, so we recommend avoiding it on both the Deck and the Ally.
