Hi,

I have numerous freeware and payware sceneries installed in my FS2004.

If, for instance, I am flying over Canada, does the fact that I have highly intensive sceneries for various parts of Europe installed cause problems for me - will they have a bad effect on my FPS?

Or does the application only load the areas immediately involved in the current flight?

Similarly with AI Traffic - if I have loads of traffic flying to and from airports within the USA, will my flights over France be affected?

Should I disable AI flights in the USA if I am concentrating on visiting airports of Europe? Would it have any effect at all?

There are so many factors affecting my FPS at any one time, I cannot decide by trial and error - so I am relying on someone knowing the actual effects from the inside.

Any ideas?

Thanks

Frames per second (fps) is affected by what you are directly looking at. If you cant see it, it is generally not affecting you.

Thus, scenery of Afganistan will not affect you if you are flying in USA. and vice versa. .. it is loaded Partially to know where it is in conjunction with other "maps" .. but it shouldnt affect you. The only way that AI and Scenery will affect you, is if you have like 10 or so Highly detailed AI programs all in 1 area with a Super high Terrain Mesh in the same area.

If you are having problems with FPS due to AI, turn your AI slider down a bit to say 50% or lower to see if your FPS pick up. But remember, any FPS above 30 the naked eye will not really see a difference in. (example: you have a 30 FPS and a 65 FPS... your naked eye can not distinguish between the 2... you will see the 65 @ the 30 rate. other than seeing a number that says otherwise)

Thanks for the reply, Capt.,

I suppose I just lump FPS problems and the stutters in the same barrel and they may not quite be the same problem. As far as I'm concerned a half-second stutter is just 0 FPS lasting for half a second. I experience both very low FPS and stutters in FS2004, despite following the many tips on the web for eliminating them.

I came from the original Falcon 4 which had bubbles - big, small, multicoloured - the air and ground battle may have been going on, out of sight in the other end of Korea, but it still had to be taken into account, and could have an effect on what was happening in the cockpit.

I wondered if FS2004 was the same - aircraft landing and taking off in New York affecting the simulation in some way while I prepared for take-off in Dublin.

Sometimes, flying over England, heading for Heathrow but still many air-miles away from it, FS2004 stutters and stalls - I just wondered was it the fact that unseen AI traffic was busily occupying itself at Heathrow, Luton, Gatwick etc, all very concentrated in one area? (Or was it caused by that flash of lightning coming from a 3-D cloud in the middle distance? Or by the sun beating in through the cockpit windows?)

I know, on landing at Heathrow, the FPS goes down to very low single figures, yet to arrive at a big airport like Heathrow and not have stacks of aircraft around would be unrealistic and is something I am (have to be) willing to put up with.

I have my own procedure for setting up AI Traffic, and can restrict it more or less to the local area in which I am flying if need be, yet I cannot say with any degree of certainty that this prevents stutters. I have removed some of the add-on sceneries but to no certain conclusion.

I am just looking for the 'official' go-ahead to have world-wide AI Traffic and add-on sceneries all over the world - and know that they were not the root cause of my troubles.

Thanks

I have to disagree. I can most definitely tell the difference between 30 and 65. I play a racing game that will always display the Frame Rate. I am usually always in the upper 60's and sometimes even reach 90's if there's nobody else playing. But I can always tell when the frame rate drops out of the 60 range, and the FPS counter confirms my suspicion.
