Only a remark how good or bad is --opencl in x264:

I am encoding in DE mode.
Two Ryzen 2700X with RX550 and DDR4-3200

using placebo preset...

With opencl enabled for RX550 I get around 13 fps alltogether, but cpu-utilization is around 45%,
when opencl is disabled cpu-utilization increases to 100%, but encoding fps only increases to 19 fps.
(this means higher wattage for CPU but lower demands for GPU)

With opencl enabled and using two encodingservers per Client cpu-utilization stays at around 45%, no increase of encoding fps.
(so opencl at RX550 seems to be the bottleneck, I am curious that opencl at RX550 seems to be slower than without on Ryzen 2700X)

Is there a possible option to enable x264 opencl for the first encodingserver per client and disable for the second one?
