AT5 standalone takes about 5 seconds to open on my I9 10900K processor O.C. 5.0GHz and about the same on my MacPro Dual Zenon. Annoying nag about try and buy, like Kenny. But since I rarely use Standalon, no biggie here.
Also, it loads in about 4 seconds as an FX in CbB. No annoying nag about try and buy though.
