Slow ground movement?

[Midnight_LS1]

Whenever I do a takeoff roll, from the beginning of adding power to til like 80 kts it feels like it's lagging then picks up speed during takeoff, it's not the aircraft i know, it's the FS9 system.
I come in for an landing, anywhere from near touchdown to braking, it does the same crap again like a really slow response to your commands then it speeds up then slows down over.

Now last night I took a 777-200ER from KJFK to KHPN for fun (on a runway that can't handle more than a MD-80 or 757  ;D )
and I taxi to the runway at KJFK, my god what a horrible system lag.  The engines spool up and the sound is heard right away and no problems with it but the time for the aircraft to start moving, it lags down again making it looking like it slows down then shoots off which is too late to brake in time and even during turns, it's so annoying!

I taxi the plane at KHPN and it does the same crap too.

What could it be?  Autogen? it's set to normal currently.
I even played around with the scenery and texture settings and they didn't help much.

I have a similar problem for fs2000 when your going fast in a concorde on takeoff it looks like its lesilury taking a walk wvwn though i have full throttle afterburners and 35 fuel

If you put the settings on low and have the same problem, than i dont know what to say?????????

[-sam-]

I have the same problem.. sometimes.
Mostly after a crash(aircraft) or a change of the airplane.

As soon as a wheel touches the ground anything goes down
to 1 or 2 fps and gets even worse as slower the aircraft is. When the aircraft is standing still again.. anything is fast like usual. Must be a bug in the collison engine ?!...

Sorry to wake this dead thread but...

Is there any new insight into this? It's just about to drive me insane. Sometimes I can do a flight fine into any airport and I never get a single second of low frame rates. Then sometimes, like today, when I flew the CRJ900 from Minneapolis/St Paul to KHIO, the moment I touched down, framerates went to about 20 FPM (Yes, FRAMES PER MINUTE), causing me to run off the runway, spin a donut, and get really, really, really MAD!!!  >:( >:( )

I even paused the sim and changed all the settings to low, and after that I still was getting a slow slideshow, though it was about 40 FPM after that.

Any new ideas?  ???

I know you said you reduced your scenery and texture settings, but did you also reduce your AI settings?  My experience is that AI becomes more of a frame hog when near the ground than in the air.
Otherwise, it may be a FS9 issue.  I do have a similar problem, as apparently do most of us.

I have something similar to that once in a while. When im coming in on final, right about the time it gets touchy and you need to really concentrate, my FPS plummets. it usually results in a crash (plane, not system). I had attributed it to my computer being old and slow.

I am currently in the process of tweaking my FS9 with a service.
I was told to have at least 50% free hard drive space as this improves it and update all drivers and BIOS to the latest avail which I did already.
And to have at least 1 gig of RAM, a 512 mb of ram is on on order for me.

Hopefully this will all clear it up and I can set the grahpics to the max and have fluid like dynamics  ;)

Hmm good idea. I haven't updated anything but my graphics card, I'll give all that a try.

I have somewhat improved the performance of FS9 on my system. I'm running XP Pro btw. Here's what I did:

Create a new user account, in my case I called it Jonathan's FS9.

In this account you want no background programs running, no wallpaper on the desktop, and no shortcuts on the desktop. Basically, don't add anything after you create the account. This keeps the amount of processor time available for FS as high as possible. You will need to duplicate your current fs settings by going to C:/Documents and Settings/[yourname]/Application Data/Microsoft and copying the FS folder to the identical folder inside your OTHER username account.

This way you won't be starting from scratch as far as settings go when you run FS in your other account. Be sure and completely log out your normal account when you change to your FS-only account. Currently I'm running FS maxed out on everything and getting about 19 fps. Even the screen resolution is maxed out at 1600x???.

My system:

2.5ghz P4, Ti4600 64mb video card, 512 mb ram.

Pretty good performace for that, IMHO

Wow... that's really smart... I may just have to try that!  Never thought of that, good thinking!  ;D

Duh, today I found out when I set the visibility to 1/4 of a mile (snow storm here today) to simulate the flight coniditons here, the slow ground movement didn't occur at all during takeoff roll, it went from 0 to VROOOOM!!!! like real life,
nothing felt like it was hesitating to move or felt like it was dragging something for a short time.  

FPS was 40 the whole time.
Werid eh?

about 20 FPM (Yes, FRAMES PER MINUTE),

whats wrong with that? the human eye starts to see flicker at below 20???

lol...Per MINUTE greg..per MINUTE! a frame every 3 seconds....I'd hardly call that flicker
