Not so good for me.
The performance improvements from SU6 have all but gone. Drop of about 7-10 FPS, stutters are back and terrain objects popping at close range as per SU5.
Add to that the issue with trackir and the ridiculous haze that means you can’t see the airport until you’re virtually on top of it when the metar gives visibility of 9999 and it’s a poor experience for me.
