Can Mocha AE be updated to allow unsupported graphics cards again?
It appears to have a bug where ticking 'allow unsupported graphics cards' (in order to get the Quadro RTX 4000 to perform motion tracking in the tool) in the Mocha AE settings does take - it forgets the setting on restart of AE or re-entering the plugin in the same session (and doesn't immediately affect the performance either).
Mocha Pro has had the fix for a while now - it sounds like it was a driver incompatibility introduced by Nvidia.
It would be good to actually extend support to all the Quadro cards to, rather than just the RTX 5000 and 6000 for this generation.

I have read there was a change in newer nvidia drivers so Mocha did not recognised the GPU properly. This bug is fixed in MochaPro but it is not fixed in Mocha AE (AE Version 2019 16.1.3).
In Mocha AE Preferences -> GPU:
"GPU Processing is not supported See Logfile for details"
[x] Allow unsupported GPUs (use at your own risk) checkbox does not help either.
So Mocha AE complains about an unsupported GPU and switches to software only which is very slow with 4K footage although I have an officially supported nvidia GeForce GTX 1080 board.

Adobe hurry up fixing this. martinb (Mocha Product Manager) at Boris FX forum said it's up to Adobe to implement the new and fixed Mocha AE version into After Effects.
