I do not believe the GPU does much in Luminar at all. If you have less than 8gb RAM it may help to turn off any background apps/processes. If your CPU is older than Sandy Bridge it b what it r. At its current price of $99 Luminar AI seems toxic to me since Luminar 4 does what I need. What I saw of Luminar AI seemed to be just a tweaked interface but fundamentally the same program as L4. I see there is a newer version which may have fixed some of the glitches. It was totally unstable on two systems I tried (often would not render back to PS, froze)-rather than giving tech support Luminar gave me a refund, which I found bizarre.

Luminar AI was kind of a hot mess in my limited experience. I have just about given up using Luminar masking tools-I would rather go in and out of PS and do the masking there or use a PS tool rather than what is in Luminar. I mostly use the AI to 'balance' landscapes, some of the tone controls are pretty good, and I prefer its sky replacement to what was recently shoveled into Photoshop.

Unless using hi bit/large color box raw data I would think processing jpegs in Luminar would rapidly lead to distortion. I would never think of using it as a primary image processing application because it is kind of slow to render, tools like masking are crude compared to Photoshop, and Luminar presets/templates can easily lead to overwrought results. I use Luminar 4 regularly but as a plug-in from PS.
