…that DxO issued a patch to PhotoLab that enabled it to work with the bad nVidia driver. but they didn’t introduce a patch to PureRAW to do that until PR 6.6.5. I installed and tested the new nVidia Studio driver 616.92 before updating PureRAW from 6.6.0 to 6.6.5, and I was able to export with no issues under 6.6.0 (or, after updating, with 6.6.5). That’s why I’m suggesting nVidia fixed the problem they’d caused. Whether that’s also the case for Nik, I can’t say.
