Hi All, I recently updated my computer to an i7 2600k CPU, 8GB RAM, solid state drives.I have tried all of the following GPU’s ATI 5870, ATI 6970 and Nvidia GTX 590I am having problems with tearing and vsync, if the vsync is on I get bad stuttering, if it is off then I get bad tearing. The monitors that I have are three Dell 1920 x 1200’s @ 60hz which previously with my old system (i7 920) worked perfectly with FSX at 30 or 40 fps. I have tried FSX running at 30 fps on my new set up with no good results. I have tried the external frame limiter at 30fps but this fluctuates. The only way that I achieve good results is by using an HDMI cable from my PC to an LCD TV which is @ 100hz, if the TV is at 50hz and I run 50fps with vsync on it’s smooth. I only use this PC for FSX, I have downloaded some demo games to test the system which have all run perfectly on the three monitors. Has anyone got the slightest idea as to why this is occurring as I have read across the internet that a lot of people manage to run the game smoothly with a similar set up to my own. RegardsJimmy

Are you running NVidia Inspector? Look here: http://forum.avsim.net/topic/324786-nvidia-configuration-guide-inspector-2xxxx-drivers-version-20-explanations-of-all-settings/

Have you forced on vsync in the fsx.cfg as well as inspector, I had to do both to stop the tearing?
