Ultimate MSFS2020 Performance Tweaker Script (For GPU-Limited PCs)
If you’re struggling with low FPS in Microsoft Flight Simulator 2020, 2024  and your GPU is the bottleneck, this script is for you. It tweaks several Windows settings to squeeze out better performance before you launch the sim — and then puts everything back to normal when you close it.

THIS STILL WORKS WITH MAINTHREAD LIMITED PCs JUST NOT AS MUCH OF AN IMPROVEMENT IN FPS AS WITH GPU LIMITED PC

What it does:

Disables Xbox Game Mode and Game Bar overlays
Turns off Fullscreen Optimizations for better frame stability
Sets your power plan to High Performance
Stops background services like Superfetch (SysMain) and Windows Search to free up resources
Disables Windows transparency and visual effects for a snappier UI
Pauses OneDrive syncing and Windows Update during gameplay
Stops unnecessary scheduled tasks and error reporting
Sets MSFS process priority to High and CPU affinity to all cores dynamically
Optimizes paging file settings for stability
And much more — over 20 tweaks in total!

You just UPDATE THE SCRIPT WITH YOUR MSFS PATH, run it, and let it handle the rest. It’s a simple but powerful way to boost your FPS without messing with your system permanently.

Expected FPS boost: Around 10-20%, depending on your system and current setup.

Give it a try if you want a smoother experience without diving into complicated manual tweaks!
