June 27, 20206 yr Hello all! I'm finished my gaming VM, and I feel it lacks of power, but I don't understand from where... Here is my TimeSpy => http://www.3dmark.com/spy/12703136 Here is my FireStrike => http://www.3dmark.com/fs/22973584 Aida64 pinned. My tower is: Threadripper 3960x watercooled Aorus Master 4*16GB ram (2 kit of DDR4 G.Skill Trident Z Neo 32 Go (2 x 16 Go), 3200 MHz, CAS 16) VM + benchmark tool installed on nvme ssd samsung sm961 I connect throught Moonlight. Does somebody could tell me where I can improve things, or maybe is that normal?

June 29, 20206 yr @Valiran Do you have any performance issues? There are a couple things you can play around with. Set the core count without counting in the HT of the VM to a multiple of 6 (6, 12, 18, 24) so it uses a full chiplet. In your case, you have selected 8 cores. That means you're using a full die + 2 cores from another one where maybe other processes from docker or other VMs are running on. The 3960x has 4 chiplets each with 6 cores. Isolating the cores you wanna use can also help in this case. You might see some better memory performance. Windows power settings to "high performance" can also help a bit. Have you tried the Q35 machine type? Maybe a thing to look at it and test with this if the performance for your specific need is better. To use Q35 you have to setup a new VM, keep that in mind. I did a quick test for comparisson on a 12core/24thread Q35 VM (16GB, 1080ti, NVME) and the numbers looking close to yours. I'm not having any issues with my VM.
