If playing Unturned in Borderless mode and having a Youtube video play with Picture-In-Picture from the web browser, Unturned limits itself to 30 FPS even when V-Sync and Framerate Limits are disabled.
To clarify, I’m actively playing Unturned while having a Youtube video layered over the game window using the web browser’s Picture-in-Picture feature
Update: Tried Picture-in-Picture video with Opera GX and the frames don’t drop as drastically as before; possibly this only happens with Microsoft Edge browser
There is probably a framerate limit for when you are tabbed out. I’m not sure if there is a setting for that or not. I think Nelson implemented something like this more recently.
