Tested on v18.08 Pro x64 dev build 1.
Settings → Multi-thread settings → core count manual override. This will not save across program restarts, it always seems to revert back to 8 threads then you tick it and use values of 9 or larger.
AMD Ryzen 9 3950x has 16 real cores and 32 threads. If I setup L3DT multi-threaded option to 30 threads it will 100% max out CPU. Only when I drop it to 26 it will hover around 96% CPU usage.
