Do I understand correctly that with 'Precision' set to INT8 the engine plays faster/better on a CPU?

Yes, that is what I read. Even if I have been only using the GPU version with FP16.

Well, I've tried it and it does not move at all.

The 1st time you run it should be from the command line, then type the 'isready' command. It should take a few minutes on the 1st run only.

PS: This drove me crazy the 1st time I tried to use it.
