I was also thinking about dual-CPU configurations. They're not typical in gaming setups and could be related to performance. I recall Threadripper 2 experienced problems in games because of many NUMA nodes and/or insufficient core handling, which is why it has a "game mode" that limits half the cores. It seems worth exploring. I've also seen another case where a weak power supply might have been the culprit, preventing the card from running at full speed due to lack of power. Could be something else to investigate.
I just wanted to express my gratitude for the assistance. My PSU is a ROG Thor Platinum rated at 1200 watts, featuring an OLED display that shows power usage. It’s unusual, but in games like Ghost Recon Breakpoint I maintain 60 FPS while only drawing 350 watts, and in Rainbow Six Siege it uses around 500 watts. It would be frustrating to manually overclock CPUs by removing cores or threads. I’m curious if disabling half the cores and adjusting threads via BIOS could achieve a similar result. I’m also aware of the challenges with Threadripper 2 and its various modes—could applying NUMA settings help my two Xeons?
During my BIOS setup, I checked for an option to turn off CPU cores. Discovering hyperthreading was enabled led me to disable it. After running the Rainbow Six Siege benchmark, my average FPS jumped from 155 to 190—a significant boost. I plan to experiment further by removing RAM modules, trying to disable cores, and even taking out one CPU unit. Thanks for your assistance. Hyperthreading clearly impacts performance on these processors.
I thought you might have a solid power supply unit, just wanted to note it since I saw someone else facing similar problems. It's nice to hear HT was turned off helped a bit. Probably won't be easy to disable an entire CPU in BIOS, but some systems let you restrict cores at least. It seems like a hassle, though—you might need to swap out one CPU to really see the improvement. As for NUMA, it's how CPUs connect to memory. If a core needs RAM from another CPU, it has to go through it, which adds extra delay.
After gaining performance disabling HT, it shows how it is probably because there are too many cores. I just bought a cooler for one cpu when I test it with one cpu. But it is not practical to remove that one cpu from the system every time I am about to game. I tried to disable cores with windows, but it did not work. I am currently waiting for a cooler so I can use it to test the one cpu.
Indeed, this appears quite unfeasible. However, it brought back a thought I hadn't considered: Windows can restrict a program to particular processors. Rather than turning off HT or disabling cores, you might manage which cores a game uses, achieving the same result. Allocate specific processor cores for certain applications in Windows 10.
I experimented with various cores and noticed my FPS decreased when fewer were active. Performance peaked when all cores were engaged.
