Now, this time reporting on the right thread:
Update ok, no issues launching.
At takeoff, there's smoke in the cabin.
The shadows of the clouds didn't flicker unlike in the DX9 version, at least not this time. Tested that on a couple dozen fields all over the map, flew below the clouds when there were some near.
Glares show allright, again unlike in the DX9 version.
ALT-S doesn't create screenshots.
The first time Alt-Tab returned to an off position frameless window. Several Alt-Tabs didn't fix it, logging out of the arena and back in fixed it for the rest of the session.
In the evening sun the shadows of trees started from a transverse line relatively far from the trees. The parallel bottom lines looked very unnatural compared to the rest of the virtual world. The morning shadows were normal.
Oh, and there was nothing on the gun sight glass. No crosshair at all.
