I am trying to change my cfs3.xml file in the CFSWW1 OVER LLANDERS FIELDS/ default file to change <Graphics OldAircraftRender="No"MaxFPS="0"/. to an FPS 32 or higher. I have found the file as per jxeboys' post. Despite getting roughly 30-50 fps (lower over ther front in 1918) I am still getting very annoying "high speed stutters. I am riding sliders at 52231. Once in this file I still cannot seem to delete the "0" value and replace it . Is there a "text editor"? If so, I cannot find it. (AMD PHENOM X49750 Quad-core 8GBsys mem NVIDIA 9800) Iv'e defragged my hardrive and shut off all spyware unused programs etc but am still gettiong a 30-50 FPS stutter show. Any suggestions would be very much appreciated.....signed simmer formerly known as johnnydrake (circa OFF 2005-2006)
