I'm also on under the impression that the game isn't utilizing the CPU Cores/threads properly. If you see my screenshot, you can see that some threads, namely 1, 4, 5, 7 and 11 are being pushed way harder (properly maybe), while others are more middle with some lower, and then there's thread 8 and 12 which lands below 20% at basically all times.
This of course, won't allow my GPU to do its job properly, leaving up to 50% of the performance unused.
This kind of performance is similar to when you play older games that are WAY more dependant on single core performance, and won't take advantage of the higher core counts.
