Had pretty much same FPS at various setting from 0 up to 48.I think it makes some kind of a difference (it felt so), maybe things generate a wee bit faster, but wasn't able to 100% distinguish between NumHighThreads of 0, 1, 2, 4, 6, 12, 24, 48.I notice that with more of them, more of my cores/threads had higher usage %, so it does something.I think maybe generation just gets split into more smaller chunks, so instead of lets say a forest of 20 trees being generated at once after a while, it generates them 1 by 1, or in chunks of 4 in 5 instances with less delay until the first ones start appearing.This is just my speculation for now for what NumHighThreads might help with.Performance wise, High threads maybe makes a difference, but no noticeable one on my end.NumLowThreads, the more you have, the more frequent and significant freezes/stutters.
