Got it. I see that now. Taking this issue a bit further, I put on my best Chuck Yeager jacket, and gathered some data. I looks like ED modeled the "WITH RAM" performance to match "NO RAM" column of the -7 chart.

Does anyone know the history on this issue? Why are we using the -3 specs when all D model P-51's had the -7 variant?

I had that using a 4080. I switched to a 4090 and it's quick again. When I ran the 4080, if I turned down settings very low and F10 menu performed well again. I'm surprised you found that hyperthread made a difference. I found that the new multithreading only used 8 cores. I tested with HT enabled and disabled and found no difference, so I disabled it. With HT disabled, I was able to increase my clock speed a few ticks. Seeing 90fps even in multiplayer now.

The i7-13700 is the sweet spot CPU as we don't use any efficiency cores. Agree on Alfred's comment on RAM, but if that's a combo that includes a 4090, I'd be tempted to do it anyway.

I fought hard and eventually was issued a refund. I had three different tech issues. Support is very poor and ultimately couldn't solve my problem. I ponied up for a Varjo Aero and couldn't be happier.
