Heavy fps drop problem

[AtomicFenix]

I haven't tested Penumbra on Windows 10, but here are some suggestions:

- Set the compatibility mode on the .exe file to Windows 7.
- Disable display scaling on the .exe.

What do you mean "move the mouse a bit faster"? Is it whenever you move the mouse or only if you move it at a certain speed?

Do you have ShadowPlay enables so that you can see the FPS you're getting?

- In the main menu when i move my mouse very slowly, everything is okay, as soon as I start to move it quicker, it starts to drop FPS. When I'm in game i cant even look or move my mouse without massive FPS drops...

- I have ShadowPlay enabled and yes I do have the FPS counter
The frames drop usually from 60 to anywhere form 7 - 15 FPS

- I'm going to try what you suggested now and I'm going to post if it helped
