104th_Money Posted May 15, 2023 Share Posted May 15, 2023 Not sure if this is posted in the right section… was wondering if anyone had experimented with unparking the CPU cores and if so did it help at all with FPS.

104th_Money Posted May 25, 2023 Author Share Posted May 25, 2023 In my quest to get the smoothest play at the highest possible settings with my 13900k/3090/64gb ram/trackir/2k display combo I have still been getting the slightest stutters in MT. I did 3 things that gave me the best performance and the last one stopped the stuttering. First, I turned shadows to flat only...during sunrise in an Apache(seems other aircraft use about 15-20% less resources that the Apache) flying over Raqqa on the Syria map with shadows setting on high would push my 3090 to 100% usage whenever I was flying into the sun. Second, I changed my cpu affinity setting so that DCS would not run on my e-cores, disabling 16-31 threads which only lets DCS run on my P-core threads. But I did notice that at any given time, half of my cores were parked which is an energy saving feature. Its strange, the parked cores varied with different threads being active then parking and so on and on. Drawback is that I have to set affinity each time I boot up DCS after I am in the cockpit... Third is that I went into the registry editor and disabled all core parking. This got rid of my stutters, as well as dropping the GPU usage by about 10% and spreading all of the work across the 8 p-cores 16 threads which dropped usage per thread for the first 8 threads from almost 100% to about 65%, the 9-12th threads up to about 85% usage and the remaining 4 threads to to about 65% usage with GPU usage maxing out at about 73%. Hope this helps someone... 2 1 Intel i9-13900k, Asus Z790-E Gaming Wi-fi 2 motherboard, 64gb Corsair DDR5-6400 RGB ram 2x32gb XMP2 profile, 2TB Crucial T700 PCIE 5.0 SSD internal, 2TB Samsung 980 Pro PCIE 4.0 SSD internal, Asus ROG Strix OC GeForce RTX 4090, Corsair 7000X Case with 5 x 120mm side mounted intake fans and 3 x 140mm top mounted exhaust fans, 1 x 140mm rear mounted exhaust fans, front mounted Corsair H150i Elite Capellix 360mm liquid cooler w/Elite LCD with 6 x 120mm fans in 3 push, 3 pull intake configuration, 2 x 32" Asus 2560x1440 displays, TrackIR5 w/pro clip, Thrustmaster Warthog stick and throttle, CH Fighterstick Pro and Pebble Beach Velocity pedals.
