1. Download and Install the "Dynamic Resolution Disabler" from the Nexus (https://www.nexusmods.com/finalfantasy7remake/mods/22). To do this just goto Desktop Mode, download the archive from the Nexus, right click the game in Steam, goto Properties, Local Files, and click "Browse". This will pop up the folder containing all your local game files. Go into "\End\Content\Paks\" and paste the archive you downloaded there. Right Click it and chose to "Extract here". It will unpack a folder named "~mods". 2. **Steam Deck Beta Update Channel Required for This Step.** Lower the game's Render Resolution via the Steam Deck game properties. Go back to Game Mode, goto the FFVII-RI game screen and click the Gear icon to open the game settings, in the General Tab goto "Game Resolution" and set it to 1024x640 and check the option to have this set "Internal and External" resolutions. This will now OVERRIDE the built-in game resolution setting, letting you FSR upscale to get even more performance with almost no visible drop in quality. 3. Optimize your performance settings. Start the game up and open your Quick Settings and goto the Performance Tab. Set your refresh rate to 45hz (honestly in some areas of the game it will now be possible to hit 50-60FPS but a smooth 45hz/45FPS is the sweet spot to my eyes, it won't be FULLY locked to 45FPS at all times, but the very slight variability that can occur is not even noticeable now), then set your Scaling Filter to FSR and Sharpness to 2 4. Lastly Optimize your In-Game settings. Set the FPS Cap to 60 (it defaults to 30, but if you want to get the most out of the performance overhead we just gained that's a waste), then set Shadows to Low (there is very little visual difference between Low and High to my eyes in this game, but the performance gains by setting it to Low are noticeable and worth it). 5. OPTIONAL - Apparently adding "-d3d11" to the Launch properties of the game can also give you some performance gains by forcing the game to run under DirectX11 mode thus eliminating much of the stutter caused by shaders loading in for Vulkan or DX12, but I have not thoroughly tested this yet. It may be worth a try combined with the above to hit even higher average frame-rates tho. A Game Reboot after applying the settings in Steps 3 & 4 may be required for the settings changes to fully take effect
