Shin Megami Tensei 5 returns as SMTV: Vengeance, for multiple platforms – including the PC. This previously Nintendo Switch exclusive game possesses modest system requirements, making it ideal for playing on the many handheld gaming PCs that have exploded in popularity recently.
Of these, the ROG Ally remains the undisputed champion of Windows-based handhelds, and a real competitor to Valve’s Linux-based Steam Deck. While you can very easily run Shin Megami Tensei 5 Vengeance on the ROG Ally, you can further fine-tune image and graphical quality to squeeze more battery life out of the handheld while sacrificing minimal image quality in the process.
A detailed list of the best Shin Megami Tensei 5 Vengeance ROG Ally settings can be found detailed below – for both the handheld and game itself.
Optimized Shin Megami Tensei 5 Vengeance ROG Ally settings

A 900p image, with a target of 60 frames per second will be used for the ROG Ally, in an attempt to maintain a balance between both image quality and battery life. The settings required are as such:
In-game settings
- Ambient Occlusion: On
- Motion Blur: None
- Anti Aliasing: On
- Screen Mode: Full Screen
- Resolution: 1600×900
- Vertical Sync: None
- Frame Rate Limit: 60 FPS
Other options, such as the in-game brightness slider can be adjusted as per your liking, and have no effect on game performance.
ROG Ally settings
- Operating Mode: Performance (15 W)
- Control Mode: Gamepad
- AMD RSR: Off
- CPU Boost: Off
- Resolution: 900p
- AMD RIS: On
- FPS Limiter: Leave uncapped/Off to enable VRR
While it is entirely possible to play the game at the ROG Ally’s native 1080p screen resolution, a severe hit to the framerate is observed. The game runs at around 40 FPS, with intermittent spikes to higher FPS values – unless the TDP is increased to 25 watts.
A 900p resolution with 60 FPS remains the sweet spot, and should net players around 2-3 hours of gameplay while unplugged.
