Hi @Special K, according to @Schlomo1933 CPU usage:
with his dcs.log:
common cores: {8, 9, 10, 11, 12, 13, 14, 15}
render cores: {0, 1, 2, 3, 4, 5, 6, 7}
IO cores: {16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31}
unavailable cores: {}
It seems that his system uses E-Cores in the most time rather than P-Cores (hope the CPU usage was taken when he was in the flight).
However, he set affinity by Task Manager fordcs.exe with all P-Cores 0-15 (with hyper-threading which matched to dcs.log common/render cores), then:
