I think it’s really an issue for people with old CPUs but powerful graphics cards (which includes me). I have an AVX2 system but it’s too slow for running TVAI (and doesn’t have a slot for a large graphics card), while the “old” system is okay for performance.
This is coupled with the apparent case that if you do have a decent graphics card TVAI doesn’t use AVX2 so it would run fine on these systems, except it won’t install… For example after a manual install I could run the Benchmark and all models ran fine (click on the blue “Topaz…” to follow link):
Which is probably most annoying for those who tested it on their non-AVX2 system (BTW I did this before purchase), found it worked and a little later they found the remaining 10 months (or whatever) of their free upgrades were no use to them and annoying issues remain… I only have a little upgrade time left, so probably won’t make it to 4.1.x and this doesn’t really apply to me, although I have a licence for 6 versions of v4 that I can’t use.
(Edit) P.S. Not everyone wants to buy a system just for TVAI, I’ve bought a Win11 system in the last 3 months, which isn’t suitable for TVAI as I already had one for that, and really have no interest in buying yet another (large) computer just to run it, alas.
