FPS drops to 0-10 when I hover the mouse over the window after the game switched to UE5
If the window is just active but the mouse isn't over it, the FPS doesn't drop - I can walk around with normal FPS, but as soon as I move the mouse over the window, it drops to 0-10.
- All drivers are updated to the latest versions.
- No additional mouse software is installed.
- RawInput buffer in the game settings doesn't help.
- Windowed, Fullscreen, and Borderless modes don't make a difference.

does it happen in the main menu
It happens everywhere.
FPS is fine when the window is active but mouse isn't over it - i can move/chat normally. The moment mouse enters the window, FPS instantly drops.
I found the solution!
I was using RBTray to minimize any application to the tray with the Ctrl+Alt+Down_Arrow hotkey. For some reason, this program was conflicting with the game.
