I run on a windows system and can’t run gpu until I can find a card compatible with my machine that isn’t going to blow it up since it’s our only desktop computer. I don’t think I can run more than one OS on this one.
The one file I was rendereing the glass didn’t have anything else on it aside from the glass material with roughness of 0, no caustics, and only had 2 lights on either side of the camera.
Suppose I could tinker around with it more and see if I can speed it up just a little bit. Trying to render out one object at hd size at 100% to take 4 hours or more seems a bit odd to me. Others that I’ve read on the forums have way more stuff in their scene takes 6 which I can understand the time on those just not the one little object in front of a background plane that I was doing just doesn’t make sense to me.
