Render with SR is slow

Hello. Im tryng to render a normal interior scene that ive render a few months ago but now im using the SR. It goes smooth till the end , qhen the generating super resolution image appears. Then it frozes there. Ive been waiting for 10 minutes for a 4k render when before that it took me 2 minutes. What can I do? Thanks in advance

You mean 2.5.0/2 minutes? 2.5.1/ 10minues? Is the scene the same one?

Yeah. Same scene same everything. Idk why can be caused

Same problem here. it’s not slow, it’s endless.

SR generates strange, ugly artifacts. See my post here:

My advice: turn SR off.
