I have to say John I'm agree with you, I bought V4 and I think that V4 need to be more optimize, Yep your ear me. I have upgade my PC to be able to use alot of the platform, I make several hour of testing with V4 alone without any add on. my goal yesterday was to just to find the same feeling I got with V3.4. In V3.4 I found the setting to be able to make turn with almost none stutter and popping autogen at 95% of the time, even with my PMDG 777,
Yesterday I was exciting with to try V4, I expect to at least retreveid the same performance. When I said performance it about fluidity not FPS (Yes I have better FPS but...) , I try to see if my flying is smooth but unfortunaly it not at my taste. I was able to remove some little stutter when I'm turning but it not like I was able to achive in V3.4,
I like the Dynamic light but when I'm use them, I point my A/C in a front of a building) my frame drop like hell, I can lost 20-25 frames (I lock my frame at 30 FPS), I don't know is it a bug or a problem on my side. But if I uncheck the option my frame rate are going back to 30...
To be able to fly with almost the same fluidity of V3.4 , I have reduce all my graphic setting lower than V3.4, even with the re install old NVIDIA driver and bla bla bla.
Overall it a good platform but IMHO it will be better after some update, and Yes John I'm agree with you, Xplane 11 is better optimize and it have a better fluidity than V4
