For those who is getting a graphic card error and your OC the card unoverclock it I heard that on a YT video last night

My Graphics Card was not overclocked when I had the error in P3Dv5.
What I did was buy P3Dv5, download it, install it, started it and configured it, exited it, THEN copied the CS757-III files over. Started P3Dv5 again, and did the two flights. After rebooting my computer, and doing the third flight, it worked fine.
