Turbo was on by default
while true, BUT: everyone I knew at the time, who had turbo buttons on their systems, told me that it made the computer faster and could lead to the computer breaking if it was left on all the time. So they just had the turbo off :|
I’ve been told this kind of belief was VERY common.
I’m fairly sure downloading/preloading shaders is a thing only for steamdeck, as the compilation result is different based on hardware & driver versions. Only “fixed” target valve has is steamdeck.
edit: actually, I might be combining two different things in my mind. Steam has downloading precompiled shaders for games for steamdeck, but has the preload/precompiling option for other systems?
