I've never had a problem with FS9 like this and it reminds me of how KPBI was in 2002 at night. Once I landed in Missoula, Montana KMSO I got 1FPS while moving. Once to a complete stop I went back to 18FPS try rolling and back to 1FPS. Took off with 1FPS and the second I was airbourne went back to normal FPS. My set up isP4 2gig512ram5600 golden ultratried both 42 and 56 drivers same resultshave renamed that gas station autop gen file as .bakAny idea guys or can anyone replica this problem?BTW found a few good fields on this flight grass next to rivers. Ten mile and Duncan in Montana.NP

It might have been a one-time deal. I just checked out KMSO, and the frames were smooth as silk. That's on an AMD 950MHz. :)

I live near there in real life!I run fine there!

It happened 2 times out of 3. I thought it might have something to do with the new drivers so I went back to the old ones. I have not had it happen at any other airport so hope yes it is just a one time deal. If you would like to help maybe do 3 t&g's there since I think it might have something to do with repeated landings. Anyway thanks for the reply and hopefully thats all it is.NP

Just done 5 t & G there - 3 on the main RW followed by 2 on the cross RW(can't remember what the RW headings were) .No problem- slowest fps was about 18(2nd landing about 1mile final), average 25- 28.Aircraft was default Cessna 172.Must be just a one-off.Dave

Thanks Dave. NP
