My render is stucked on few tiles on the right, I don’t know what it can be, I had no problem few time ago, maybe I touched something in the parameters. It seems do do the same with the CPU render. The remaining time is not moving.
Things you can try.
Make sure that your viewport preview is in solid mode and not render preview mode before hit F12(I noticed if i left the preview at render view and hit F12 that the renderspeed is reduced alot).
Then try smaller tile size.
I find, that’s because I was rendering with my GPU AND my CPU. So the GPU tiles finished and it last the CPU tiles which are too big so it stay stucked. I just render with my GPU and it work Thanks !
