Hi,I am having a problem with FS9 which has been driving me mad for ages. The game will quite happily run at a reasonable frame rate for a while and then, for no apparent reason, will slow down to an unmanagable frame rate of 1 fps. It occasionally happens as I am taxing from the gate to the runway. Landing also causes problems, it is fine on the approach, nice and smooth frame rate, and then the minute the wheels touch down, the frame rate plummets to 1fps.Can anyone help? Any ideas?

sorry i cant help with problem here., but it looks a little similar to a thread i saw about feedback problems. On it a guy said he was getting low fps on landings and fixed it by uninstalling FFB settings- just thought i mention it here on the offchance it might be related to your problem!dsflyer.,

Ah yes, annoying problem of low frames on approach, go to your Main FS 2004 directory, open the folder autogen, in there you will see a .XML file, rename it to something like slowdown, stupidfile, anything that doesnt have the default name it, this should make a big difference, what this does is remove certain autogen objects like fast food restaurants and stuff, most people never notice these so why have them slowing down your system?

follow up on that thread., he was actually getting about 1-2 fps after landing and fixed it by removing all FFB related to ground bumps only

Also, open up the FS9.cfg file, go to the Graphics section, and change the line TERRAIN_USE_VECTOR_MAP=1 to read TERRAIN_USE_VECTOR_MAP=0.Doug
