UE4 and 5 games already have pre game compilers for shaders, It’s already obviously a thing that can be done and is done in AAA and indie games alike.
I’m asking how to do last moment GPU shader comp on first launch which again is something people already do.
I’m not asking what is causing stuttering or how to have the game live compile from source like a game engine, I’m asking how to solve this specific problem with a solution that is already out there but just doesn’t have any documentation.
