>>713284627static scenes rendered twice (or rather an entire facade of the scene on the other side of the mirror) with a full forward rendering pipeline would be massively cheaper than current deferred rendering and ss/rt reflections, since if there's anything GPUs can actually handle well, it's drawing a fuckload of triangles
it's just way more work for the devs and more limiting, like if you want to have a mirror in a space that isn't a fully enclosed room you have to start accounting for a bunch of edgecases where the player's going to do something that makes the reflection look like shit, like walking around the side of the mirror
idk maybe portals would work
>>713302193not necessarily true, more mirrors means you need to allow more rays and more bounces for it to look right, which is an exponential cost increase, then you also have to take in to account what your update rate is. a house of mirrors for example would look like absolute shit with half second update 2 bounce rt
