Hi @RichardMH
Yes, Open CL is still enabled, and Nvidea GeForce RTX 3050 (laptop GPU) selected for DeepPrime acceleration.
No other apps seem to have slowed down, so I think this is the Windows version of PL working differently to how I was used to with the Mac version of PL. ie with Windows, leave DeepPrime disabled on all images until you are ready to export them. On my Mac I can comfortably edit even with DeepPrime enbabled on all the images all the time.
It also turns out my Windows setup was set to have HQ noise reduction on by default, whereas on my Mac I have noise reduction switched off completly by default. With my earlier export test with the laptop I thought I had NR switched off altogether. HQ actually takes longer to export on my Windows laptop than having DeepPrime enabled (I’m guessing because HQ is CPU only, whereas DP uses the GPU for export), so that squewed my export times to be longer than I expected.
Switching off NR completley or enabling DP has brought export times back down to more familer times, and having DP switched off whilst editing has made the editing expereince return to normal.
Not a big issue now that I’ve leant how the two OS versions vary in these regards. I am much more familer with PL on a Mac, so this has been a learning expereince
