A steady frame-time curve matters more than a peak FPS number on handhelds. Use the same scene to compare profiles, then set refresh and power caps through the device’s performance interface.
Start with 1280×800, High textures, Medium foliage visibility, and a 45 FPS cap. On Steam Deck OLED, try DX11 first for predictable frametimes, then test DX12 if a supported upscaler feature justifies it. These are starting values, not guaranteed 45 FPS in every town or storm.
Use the reversible tests first; hardware, driver and game versions may change results.Test the fix before changing your game

Steam Deck OLED
Try DX11 for stable frame pacing; DX12 is a separate test.

Target cap: 45 FPS
Pre-session scan
Preset suggestions; not an FPS guarantee.Follow these steps in order
Choose your handheld first
Select Steam Deck OLED or ROG Ally X. Start with native 1280×800 rather than changing several graphics variables at once.
Use a stable renderer
Try DX11 if DX12 causes spikes on your device. Do not assume Intel XeSS Frame Generation or XeLL works on every handheld GPU; check in-game availability.
Tune quality for consistency
Set foliage visibility to Medium, textures High if memory permits, disable heavy ray tracing, and choose a stable upscaler available on your hardware.
Apply a suitable refresh and cap
On Deck OLED, pick a suitable display refresh and cap 45 FPS if supported. On Ally X use its refresh/frame-limit controls; retest in busy towns.
Use touch for suitable menus
If the build accepts touch input, test Gwent and inventory navigation. Keep controller inputs for combat; touch behavior can differ between operating systems.
What to check before calling it fixed
Repeat the same scene or test after each change. Save a record of the settings that worked and keep a clean backup so you can reverse any unsuccessful tweak.
Frequently asked questions
Is 45 FPS guaranteed?
No. Dense scenes, mods, CPU load and thermal limits may prevent a consistent 45 FPS.
Should every handheld choose DX12 with XeSS 2?
No. Feature support varies by GPU, OS and game build; DX11 can be smoother.
Should textures be High?
High is a sensible starting point if memory pressure is controlled.
What about ROG Ally X resolution?
1280×800 is a performance-first option, not the only supported output mode.
Can I play Gwent using the touchscreen?
Test touch input in your current game and operating-system configuration; game versions differ.
