I’m well aware how to make games, thanks, I’m the tech director on a AAA game with 15 years working on them.
I said “constantly” rendering and you and everyone seem to have taken the least charitable interpretation of what I said and decided I couldn’t possibly know what I’m talking about.
Sorry to ressurect but having just experimented with reducing redundant renders in my own game, which isn't even fully real-time, I'm with you. Trying to know when a game may or may not need a new render is a tricky problem, glitchy if done poorly, and ultimately battery life in games seems like a (high priority) nice-to-have... Shame you're getting flack from folk that clearly haven't ever shipped a game.
