ASUS ROG Ally Optimized Settings
Note: the gameplay video above is captured with an
AVerMedia X'Tra Go GC515 dock/capture device, which doesn't affect performance in any way. What you see is what you'll experience on your device.
If you want to play Kingdom Come: Deliverance II on your ASUS ROG Ally, set the resolution to 900p, FSR to "Quality" (the game looks better at 900p with quality upscaling than at native 720p), and select the "Medium" preset. Then, increase "Vegetation detail" and "Character detail" to "High." Lastly, set the level of sharpening to your fancy. You can set TDP to 25 W, or 30 W when hooked to a charger, and keep VRAM at the default, 4 GB value.
This settings combo results in a surprisingly stable gameplay experience that ranges from the low 30s in dense woods to the high 40s and low 50s in many other areas. There's some stuttering, but it's far from annoying. The game feels even more fluid than on Steam Deck at 30 FPS, thanks to the 120 Hz VRR screen the Ally is equipped with. We can say that the overall gameplay experience is near-flawless for a handheld gaming device.
Now, if you want to push the device to its limits, you can increase "Object quality" to "High," and drop "Vegetation detail" to medium to take a couple of frames back. This results in a very similar performance to what you'll get with our optimized settings but virtually eliminates distant object pop-in. On the other hand, increasing "Object quality" to high makes stuttering more frequent and annoying.
The game looks quite good at 900p with FSR set to "Quality," which is very similar to native 900p because SMAA isn't a temporal stability champion. While the image quality isn't perfect, the game itself looks quite clean on ROG Ally.
There's some distant object pop-in (which goes away if you set "Object quality" to "High"), but other than that, the digital recreation of the 15th century Czechia is a lush world filled with verdant meadows, flourishing forests, and picturesque settlements, all of it bathing in warm sunlight, at least when it's not raining.
Our optimized settings combo results in less than one hour of battery life.
If you want more juice for out-and-about playing sessions, we've got you covered. The battery saver settings combo is made of 900p, FSR set to "Quality," 15 W power profile, "Medium" preset, and "Shadows" set to "Low." These settings result in a stable 30-ish FPS experience and a surprisingly good-looking game you can play for about two hours on your ROG Ally before its battery dies.
