this is very odd, anyone else experience this, during daylight hours in the sim, i get 2.6-7.6 fps depending on the planeciao!Brian S

Known problem, caused by problems with turbulence affecting frame rates. Strange but true! Download Peter Dowson's FSUIPC.zip if you don't have it already, and see the readme file for details on how to fix the problem by disabling the turbulence.It is amazing MS did not spot this problem because it occurs in one of the MS provided Euro Transport Pilot adventures. Don't mention the p.... word :)

aaahhhh.. thanks, i used to have enable turburlance off, but i have turned it on about 2 months ago, lot more fun to fly in. but ok, i'll give that a try, very strange indeed.ciao!Brian S
