on TG3 that is. This render did it, though it was just a test with clouds. It may not look too impressive to you, but it has always been a challenge for me to create decent looking rain clouds. Disregard the terrain, I only spent a couple of minutes on it and it's way overlit (too much enviro light). I maxed out the TG3 Free quality settings here. Almost 3-hour render time, but that is on an M520-powered laptop (still got 8GB of RAM). My render rig will be able to handle that quite a bit faster.
BTW, why was the label changed in the render node to "Defer atmo/cloud" from RTA? Just curious.
Finally got the upgrade (from TG2) transaction done, hope my key arrives not before long
