How to enable or disable Full screen optimizations on Windows 11/10

Full-Screen Optimizations is a feature on Windows devices that help them function better. It is enabled by default for applications like video players and games. When this feature is enabled, the gaming or video playback experience is enhanced by prioritizing the CPU and GPU resources for that particular process. But sometimes, it results in a drop in the frame rate (FPS) when in full-screen mode. The solution to fix these frame drops would be to disable these full-screen optimizations. But unfortunately, Microsoft has removed this features for Windows 11/10 in the recent releases – but there is still a way you can get this done.

In this guide, we will cover the following ways:

1] Using the Registry Editor

2] Applicable to a particular set of users

3] Applicable for all the users

4] Using Windows 10 Settings

Hello friend 🤗, can you help me with this ? 👉 switching to resolution 1366x768 failed screen: dx11 could not switch resolution (1366x768 fs=1 hz=0)

I can't do it through registry. It's impossible for me to globaly turn fullscreen optimalizations off. I've tried many tutorials. If I check this box in exe's properties then it works, I don't have 60fps cap and move screen delay making games kinda unplayable.
Registry line you propose is GameDVR_DSEBehavior which is interesting cause other turorials saying it's GameDVR_FSEBehavior. Tried both, tried both numbers 0 and 2. Doesn't work for me. I even installed older drivers and turned vsync off in intel control panel. I just can't turn those fullscreen optimalizations off globaly on my PC.
