[BUG] Fullscreen reduces FPS

[Fluxelux]

I run Foundry smoothly at 144 FPS, but whenever i switch into fullscreen with CTRL + F11 it caps the FPS at 85, although it feels more like 20~.
Switching Foundry's Performance Mode from Maximum to High caps it at 60 FPS but it runs way more fluid.

Going back to windowed mode with CTRL + F11 makes it run at 144 FPS in maximum mode though.
I do not have any of those issues in my browser (Opera GX) and the issue persists on different maps, worlds, and game systems, so its not a module issue either.

I found another issue with it: If I stream on discord (no matter if I stream FLC, my steam library or whatnot, it runs on 144 FPS stable?!

I can't make sense of it.

It's probably a WebView2 bug. Nothing in FLC itself would cause a difference between windowed and full-screen modes. I suggest keeping your Windows updated to ensure that your system's WebView is up to date.
