I agree SM should have devoted time to fixing the RTX problem, their reply on the SM forum was that RTX cards at the time were not popular. Bondware priority had to be get a working version of poser ready for when SM closed the servers. As you pointed out yourself, there were problems with this version. Bondware was picking up Poser from scratch, with a very short time to get 11.2 out. I'm sure most people would agree that it was better to have a working version of poser 11 rather than wait until they had also sorted out the GPU rendering

Poser 11.2 was not a luxury, it was a necessity to keep Poser running.
