Nope,did a clean install and benchmarked it against other popular planes like Fenix,pmdg,flybywire etc,.. and the performance is still significantly worse,fingers crossed 1.0.9. is performance oriented.
Experiencing the same performance wise,it used to be okay enough to fly now I can't use it cause of the low fps,last i flew was 1.05 or 4 i think,updated to 7 and couldn't even land due to the fps drops and stutters,such a shame I really enjoyed flying it before,i guess there's no way to downgrade back to earlier versions
