With the exception of the highly annoying not being able to manipulate and click the toolbar issue in VR, I have found this SU7 update to be pretty darn solid for me. My performance seems just as good in my Reverb G2 with Open XR, no problems there. And I have logged close to 10 hours of flying now without a single CTD which is almost unheard of for me.
In fact since the update I have only had one CTD and that was early on when I switched to the DX12 Beta just to check it out. Had stuttering and then a CTD a few minutes into the flight. Switched back to DX11 and so far not a single crash in DX11 since I updated.
As far as the annoying issue I mentioned earlier, I am using the work around by assigning Instrument View 10 and Reset cockpit view to two buttons on my flight stick. So I can have ability to manipulate toolbars with one press, and ability to VR Zoom again with another button press. I hope they issue a hotfix soon for this issue.
