Hi!  
I tried the [setting volume partitions](https://discourse.slicer.org/t/stitching-artifact-with-volume-rendering-large-volumes-feb-17-2021-nightly/16390/16) method on 3090 opening the eyeglobe data and used 2, 2, 2 and 4, 4, 4. They both negatively affected volume rendering speed. Most obvious was under normal method, it became very laggy. No difference was observed with 222/444 under maximum quality, every rotation movement took about 5-10 seconds, if the movement was too fast, windows will close slicer. I did not dare to test change TDR delay, as I’m not very handy with computers, it felt dangerous…
