Hi. My ready 11 is much slower than ready 5. I have nvidia rtx2060 and 32gb ram , win10. Version5 is still the fastest. What am i doing wrong?

I just compiled and ran and tested the trunk of Ready and it seemed plenty-fast (or at least as-fast-as-usual) to me. (this was on a fairly old linux workstation with a mere 384 Nvidia-GPU-cores)

I wonder whether the problem above might be perhaps something like the newer (>5.0) mac builds aren't getting to use the gpu with Ready's OpenCL perhaps? Missing GPU may perhaps explain the degree of slowdown, epecially on a 3d-pattern.

Might be good if we could try to get some more diagnostic info from "Weird Struct" too perhaps?
