Additional settings for Persona 3 Reload, HDR, TSR, FXAA, No AA, Shader Precompilation and more

This UE4SS script will allow you to adjust sever settings in Persona 3 Reload. It's fully compatible with P3RFix by Lyall.

This allows you to:

• Enabling 10 bit HDR Display Output
• Switching between original TAA, no AA, FXAA and TSR
• Changing streaming pool
• Adjusting sharpness
• Adjusting Anisotropic Filtering
• Lowering quality of shaders
• Disabling Shadows (speedrun any%)
• Disabling Eye Adaptation
• Disabling Screen Space Ambient Occlussion
• Disabling Bloom
• Disabling Screen Space Reflections
• Using SSR in places where it doesn't appear on non RT cards
• Forcing Ray Tracing on every scene
• Disabling a lot of PostFX effects
• Disabling texture streaming
• Enabling Shader Permutations Precompilation

Known issues:

• Enabling TSR breaks some viewports, like some special attacks and city map view
• Enabling shader precompilation causes delays and stutter in loading screens and on scene changes

Installing the thing:

• Download UE4SS and unpack it to your game installation folder ./P3R/Binaries/Win64 or ./content/P3R/Binaries/WinGDK
• In the same folder open folder Mods and create there P3R_AdditionalSettings and in a newly created folder create scripts folder
• In the scripts folder put attached main.lua file
• In mods folder open mods.txt and add there P3R_AdditionalSettings : 1 line and save the file

thanks bro, spent a lot of time to search this solution to improve P3R performance on my overheating gaming laptop. Just added some new lines and my videocard W goes brrr: 75W -> ~40W

Good to know that it's useful :)
