@DocBobB and @Egregius My experience with the St Pancras Station image shows the export process with AI Presets, in particular ‘Sky’, ‘Vehicles’ and ‘People’ and with an additional set of user selections for the building.
The presets are used alone or in combination and the following is the result on my 5600G(32GB) + 3060(12GB) with PL9.4 (Nvidia 591.74) and with NO NR set.
VC[5] omits ‘People’ because in tests on earlier releases the ‘People’ preset was failing!?
Typically I expect that after one failure the export worker becomes “screwed up” but here it managed just fine but I did terminate the export worker between the two tests!
I terminated the export worker and ran a test with XD2s set on all copies and got
i.e. ‘People’ failed this time and may well have been responsible for the failure of VC[6].
So when these tests pass without incident on a release of PL9.x I will consider it well on the way to recovery and create a large batch and run them on both my machines and if they pass then I can start complaining about the impact on the speed of the UI!
