Performance question

Hello! I have done my first flight with the CRJ, she is nice. But I experienced weird performance problems... I had most of the time around 20 FPS, which is enough for me, but the overall performance was very stuttery with occasional freezes. I know, the CRJ is not the only reason when it comes to bad performnace, but I have setup my FSX to run smooth in most conditions with most of my aircraft. I just wanted to know if there is a focus on performance in some way for the fu

Yep everything is installed I understand your point of view but I'm a bit desapointed. I lock my frame otherwise I have bouncing frames and it kills the smoothness of my sim. I've tried again to unlock the frames but it's worse.. Believe me I prefer flying than tweaking. As I even remove the small OC of my CPU and nothing changed.I just want to understand what's going wrong to fly this gorgeous lady. I'm not blaming the product as I'm always happy with your birds.
