Hello,
I have exactly the same problem with Low performance like you described. Below is a little more info about the problem which I found during testing but they appear only on A32NX aircraft.
During outside view everything is normal (good FPS, GPU load between 90 - 100), when I changed on Cabin View, FPS dropped due to CoherentGTUIThread limitation and GPU load was decrease to 60 - 70.
I have installed A32NX 0.7.3 the latest DEV version and a problem with low FPS due to CoherentGTUIThread limitation. During T/O the value of the CoherentGTUIThread increase on 45ms (MainThread=20, GPU=18) and this is the reason that I have FPS below 30.
The value of the CoherentGTUIThread is changed during the different phase:
- On Cockpit Dark and Cold is 15ms
- After Engine start is appr. 30ms
- During Take-Off is 45ms
Another think is that the GPU Load is at the beginning (DARK and COLD) 90% and than dropped to 60% - 70%. CPU load is between 40% - 50%.
On all other Aircrafts CoherentGTUIThread is normal and have not impact on FPS and GPU loads is 100%.
I use 1920 x 1080 on DX11, more or less HIGH END settings on notebook Asus G752VS with i7-7820HK, GTX1070 (8Gb) and 32Gb.
Nvidia driver 496.98.
