That benchmark doesn’t state what cpu is being used and only represents the performance of the card. Its not only about GPU performance. CPU performance (especially ipc and frequency) and good memory is just as equally as important in extracting the maximum performance from this sim. Going too far in one direction or the other will most likely result in stutters. Which some people were complaining about when the sim was released with their imbalanced systems.
User needed a 5600xt to ensure he is getting the maximum out of the card and isn’t leaving frames on the table (especially in complex scenery situations where the sim leans on the cpu the most … at times leaving the gpu waiting to be given frame instructions).
And from his response it was the correct decision.
