I down loaded Pure Raw 6.4.1 a couple of days ago and finally got around to installing it. The first thing (test) I did was change my Preferences from the Intel NPU to the integrated GPU after updating the driver for the GPU. I am using a Surface Business computer (Not a muscle machine) with Pure Raw 6. I loaded an image of a Mobula Ray I took while anchored off Cabo San Lucas with a Canon R5 Mk 2. It took a little under 2 minutes to process the file using XD3. It still counts up to 10 or 11 minutes left before diving down to finish up in that time. The time was measured using the stopwatch on my Fenix 7 watch so it should be close.
I missed any announcement of the update to PR 6.4.1 and the file description was only bug fixes. I’m happy to be able to use either NPU or GPU and get these results.
