I should be able to answer my own original question in regards to Zen2 vs Zen3 this weekend. 5800x is out on the truck right now!
Any suggestions on how to test? No built in benchmark. I’m thinking change settings so it’s mostly cpu bound, but not low low settings. Then just start up at the same airport with constant conditions. Waitfor the framerate to settle in and see what I get with both.
I have a 3090 so cpu bound a lot anyway.
