Low FPS on first run of exe. Fine on second+

Hey there @Coyotekins_YouTB1! It sounds like for the first run the shaders were being built and cached. This is a somewhat intensive process most of the time, and modern games tend to cache those in a menu when the game launches.

It’s recommended to load the shaders before the game can be run to avoid what you’re seeing now.
