My “meh” performance comes when popping out instruments to use in my cockpit setup. While SU5 did get me back up to a mid 40s for most planes (without pop-outs), that 15 fps penalty I take as soon as I pop out any instrument pretty much negates that.
Well, mostly. After SU4, I was struggling to reach 20 fps. At least now I can hit a solid 30 most of the time.
It’s still a far cry from the near 50 fps I was seeing at launch though. Even with a couple of polled out instruments, I was still seeing 40+ back then.
