I purchased a Radeon HD 2600 Pro yesterday and intalled it using the latest Omega drivers. I installed a fresh copy of FSX and flew the sim and had zero problems. The sim ran very smooth with no blurries or stutters. I then installed SP1 for FSX and still the sim ran smooth with no problems. Today when I started the sim I am getting stutters like crazy. Its so bad that the sim is unflyable. I have my frames locked and 20fps, but they drop to around 3fps about every 5 seconds. I checked the task manager to see if anything could be causing this problem, but I have found nothing. I just don't know what could make it run so bad today after it ran so well yesterday. I have done a disk defrag and uninstalled a few programs that I thought could be the problem, but nothing works. Is anyone else having this problem while using the Radeon HD 2600 Pro?

I found something a little strange today when I looked in my FSX folder. All of the folders had (2) next to them. Im not sure how all of my folders got duplicated. I am going to whipe FSX off of the computer and do another install. Could duplicate folders cause the stutter problem?
