Wow! I am testing now, and it’s a pretty major speed improvement!
I’m running Windows 10 64bit, with an old 980 TI OCed.
Trying subDiv Level 3 on a mesh:
Toggle into Edit mode:
2.93 - 5 seconds
3.0 - 1 or < 1 second
Soft Selection Movement:
2.93 - Doesn’t even work/never even starts to move. Keeps lagging out for a long while.
3.0 - maybe 5-10 FPS, but can somewhat interactively move the mesh/verts!!
Edit: Also, running my cloth simulation/modifier stack in 3.0 vs 2.93.
3.0 is definitely more “interactive” with the viewport updates, where 2.93 stalls out again/i can’t see what’s going on and gotta just try and stop the playback/wait for it to update.
