Multi-core processor sluggishness
My current configuration is Epyc 9654 CPU and DDR5 ECC 4800MHz 128GB RAM. No matter how many cores I set to use for rendering, as soon as the rendering process starts, my computer will be very slow, regardless of how many cores are occupied.The version used is CR V13.1 and C4D 2025.3.2

Re: Multi-core processor sluggishness
Just for a test, could you please try disabling SMT (simultaneous multithreading) in BIOS and see if there is any improvement in the overall system performance?
