ChatGPT suggests the former, I always thought it was Core0 on this CPU based on watching utilization by core over the years. This question is posed as I am flying the Longitude to KTEX right now and am amazed at its sophisticated avionics and yet Core0 which usually hovers around 74-84% with the premium airliners and yet on the Longitude is a paltry 14-16% flying over Denver. That's stunningly less and yet again it's got a lot going on in it, the Longitude. Is it correct to say because of this CPU's big L3 cache there really isn't significant gain to be had with faster RAM, correct?

September 25, 20241 yr Fixed for what I could observe on my PC running MSFS. It's "CPU 0" for me. In your case, are you sure you're not GPU limited? Or that for some reasons MSFS chooses a different thread to hammer? Your observation on the RAM is partially correct: in CPU limited conditions my PC delivers about 10% more fps with EXPO I configuration (6000 MHz) with respect to the default setting at 4800 MHz. 7800X3D | 2x32 GB DDR5-6000 CL32 | RTX 5080 | Alienware OLED 34" | 1 Gbps fiber
