As reported in the 7.2.0.3b Thread the second iteration of SL mini does work MUCH better than the (quite unusable) 7.2.0.2b one:
Quality has gone up by a big margin and speed is OK (0.3fps for 2x SD upscale on a M2 Ultra) and the process is running stable here. Main problem seems to be M3 chips (again!) and the HUGE RAM requirement - filling up 62 GB of my 64 at times.
