problem NVenc h265 2160p 60fps

[Bruno999]

Hello, I wanted to test an encoding with NVenc in h265, it works in 1080p and 720p but not with the resolution 2160p . An error message appears "Current macroblock count per second (1.95326e+6) > maximal allowed macroblock count per second (983040)!" (see attached file + debug file). I also convert from 30 to 60fps with vapoursynth at the same time, and if I disable this option, it works ... Is there a solution for this to work in 2160p 60fps?

Thank you.
