So I finally got to install a new Threadripper 3970x system today… which is GREAT!.. but something is not going quite as expected. When doing light builds in UE4.24, it seems to be using only half the threads.
Difficult to say if it’s caused by multi-threading not properly working or if some cores are just barely used (however, Ryzen Master is telling me that some cores don’t even speed up, so it seems. For sure the scene is big enough though, with 2000+ actors to be baked. My good old 16 core Treadripper 1950x always showed a neat 100% utilization throughout the light build.
What is happening here?
