Back in October 2015, I purchased a new PC for flightsim.

Specs are:

-I7 4790K

-8GB RAM

-Zotac GTZ750Ti 2GB 

- CIT 500W PSU

-ASUS H81

-1TB HDD

-Windows 7 Home Premium

 

After two months, I got white dots all over my screen while playing flight simulator, I returned my card and was told that it was faulty. I received a replacement a few weeks later and installed the card. On the original card, I was getting a decent amount of FPS with heavy scenery and addons. Even on integrated the performance was still pretty good, my replacement card is now giving me 20FPS less then what I was getting on the original card! I noticed in my FSX settings that under display device there was two entries for the GTX750Ti. A screenshot is attached with this post. I have so far tried reinstalling drivers numerous times and have also reinstalled the card into my PC.

Delete your fsx.cfg file (back up first) and let FSX rebuild it.

I just tried that and used the settings that I originally had and the results are still the same :/

The two entries are still there aswell for the graphics card.
