Hi.
I was initially replying to Philippe Mathis who was having problems with Starlight and Alan Husband pointed out he was using an under powered GPU and I subsequently, posted the Topaz System Requirements confirming this so, Philippe could see that this was the probable cause for his issue.
So, I’m afraid I don’t know the history behind the AVX as I virtually switched my computer and Window 10 to 11 when Windows 11 launched and was blissfully unaware of the fiasco.

There’s a lot to be said for having something that just works and being unaware of issues that might have but didn’t affect you 
Oh and I’m wrong, yea - they had changed it so AVX2 was required and I stopped updating as my (much faster than many AVX2 CPUs) processor didn’t support it. However some research shows they subsequently/deliberately removed the need for AVX2. Would have been nice to get a message as I asked both here and directly.
In a post from a Topaz person:
”AVX is a requirement for the app, there were a few versions that required AVX2 however, the requirement was removed and replaced with a warning to let the user know that it is not guaranteed that everything will work.”
(From: Video AI Requirements )
I’m not sure how helpful it is with that warning tho…
I do also wonder about the requirement for a CPU “released” after 2020, as that excludes a very large number of CPUs sold this decade and allows CPUs like the N100, which is mind-blowingly slow for number-crunching, while excluding ones many times faster, like Comet Lake (10 cores and 20 threads at over 5GHz in the i9-10900K, for example, released pre-2020).
P.S. Note that while the N-series officially only supports up to 16GB some manufacturers have made systems with 32GB work, plus it supports 1x8+2x4 PCIe (e.g. RTX5060ti/16GB), so it does quality. Just don’t tho… really…
Certainly interesting regarding the AVX and AVX2 plus the i9 10900K and the Intel N Series N100 I must say this is very informative to know
Though please do note I’m commenting on their requirements list, rather than what actually happens in the real World…
Yes, I feel the same: something was removed from the Studio version without any change in the interface. It even does a “good to go” test and the models are displayed and you can click on Starlight and the process starts until it comes back with an error once it has loaded the model in memory.
Several users of Topaz are home users and fans and I feel like the carpet was removed from under our feet. Studio Pro costs $700 in Canadian dollars. I am going to let go of my project of improving my family videos at this price. I only subscribe to it to prove a point.
