You are completely incorrect with your guess on who does what in game studios
I’m definitely not. DLSS support is a low level engine feature. The engine developers working on this are not working on content.
DLSS support should be in the engine before there is even any content - it should be there before there’s even a playable build.
In general no, they don’t. Engine programmers aren’t designing levels or characters or missions.
Also as I said, DLSS support should be in the engine before there is even any content.
