S!
Thank you for the answer Oleg. So it seems I can safely buy the new high end Radeons next month
Their drivers have improved a lot and in DirectX 11 they are working just fine and in new OpenGL versions 3.2 and above. For some people it is just easier to blame the driver maker rather than bug in a game code..compare to the FPS games where both nVidia and AMD have problems due bad coding so they have to make own hotfixes or workarounds.
As of the clickable cockpit. Fair enough on the start-up. But the bandwagon should remember that even we have clickable cockpit to a degree, MOST do NOT use the important things with mouse but on a HOTAS or similar. I will use the least needed functions with mouse and program most critical ones to the HOTAS as I've done with IL-2. So really no use to make mouse control look bad. And there is a plethora of simulation stuff(extra switch/rotary boards, multithrottles etc) you can buy to make a cockpit like environment
Soon I run out of time, RoF, SoW, IL-2 and EVE Online..aaargh!!
