FSX automatically reduces the display resolution using some unknown (to me) criteria. Has anyone uncovered a way to prevent this automatic action?Regards,Dick Boley

Hi Dick,not sure I'm following. Are you talking about the switch to lower mip-maps (i.e., the "blurries") when FS gets "under stress"? If so then there's no way of avoiding that I know of (other than pulling sliders to the left for display and AI options); something has to give and I guess the devs thought that blurry terrain is easier to accept in a flight simulator than losing control over you aircraft or have AI drop out of the sky etc.Or maybe you're talking about something else entirely?Cheers, Holger

Yes, the blurred, or lower resolution, as a result of perceived performance issues during flight. Actually my FPS never go below 18 prior to the occurance. However, there MAY be other criteria involved. I would prefer a way to disable the "feature" to see if I would actually suffer a catastrophic event.The trigger is that I have over a gigabyte of hi resolution (1 meter) photo scenery around San Francisco which upsets the program at times. I did find that if I ran a memory optimzer prior to FSX it does not occur. Only 1 gb of memory. Regards,Dick Boley

Hi Dick,Usually these blurries mean that your video card can't cope with all the data that is being send to it. But sometimes other parts of the PC can also be a bottleneck of course.As Holger suggested usually reducing the settings a little bit should prevent this problem.
