I wanted to experiment again DSR 2 with FSX on my Nvidia card 680 day before yesterday and from there started a stream of problems which I cannot understand and resolve.

 

First of all I reinstated the video settings as they were before (i.e. 1920x1080) and removed DSR. But all my settings with my hardware (Yoke, rudder pedals, throttle quadrant) and FSX in game shortcuts were lost. FSX does not keep those settings anymore, each time I start FSX, they are lost again and I need to re input everything from scratch. I regenerated an FSX new CFG file, to no avail. This morning after doing all this I made a flight with no problem other than my CDU and Kneeboard being invisible in full screen (They would appear in window screen).

 

I would welcome any guidance to resolve this issue.

Many thanks.

OK I found the probable causes and solutions to my problem. I believe that it was provoked by having to restart my PC after it froze with FSX being opened. On the first account when attempting to use DSR, my screen in FSX was blurred, and I had to restart my PC as no command would work, following what my settings were lost for the first time.

This morning after updating GSX Couatl for one airport (I really hate this system as it seems to freeze FSX each time we use it), again my PC froze and task manager would not be able to close FSX, a following PC restart again appeared to have lost my settings.

 

I finally created a brand new FSX CFG file on which I copied my archived reference FSX CFG, and I am back in business. After restarting FSX five times with different sceneries and aircraft, everything works as before.
