    FWIW, I did a quick test on my Ryzen system using C-Ray.

    I found that with -O2, compiled with gcc 10.1, it ran around 3% slower than gcc 9.3
    With -Ofast -march=native, gcc 10.1 version ran about 1% quicker than with gcc 9.3

      It's been a long time with no updates. No one can confirm the issue.
