I participated in the Beta Windows program and had to uninstall it after a few tries. I loved the features but if I had 2 photos loaded it would lock the computer up so tight that I would have to do a hard-reboot. A that tiem the hard-drive would be spinning madly (the light would be on continuously for minutes). It is the only program I have had issues with: PS CS, Elements, DXO, Affinity and Cyberlinks Power Director Video are all fine. I was hoping for more luck with the release version.
I have Windows 10 and use it as a stand-alone. I did a simple test this morning with the same 18mb jpg photo. I did one simple adjustment with Luminar and exported the image to a new location and it took 90 seconds (as in a minute and a half!), with Affinity it took 9 seconds. I hope they correct the issue before 30 days or it's bye-bye Luminar until I hear it works better.
