Yesterday I downloaded FlightGear onto my hard drive with plenty of free space. The end result was a system that moved at snails pace in all areas. Today I was forced to delete the programme and all is back to normal. Very sad, as I have always wanted a flight sim.If anyone has any suggestions, I would be pleased to hear.Thanks, Joe

Hi thereI'm kinda baffled...Flight sims require lots of ressource.I have FightGear running on XP without a problem flying daytime... It stutters a lot with night lights :(Specs:Athlon XP 1900768 megs of DDR333 RAMGeforce3 TI 200 vid card.All this on a sweet MSI KTA 133 Ultra motherboard :)I also did lots of tweaking when I installed XP, 18 or so months ago. There are many good tweaker sites out there. Find one with language you understand better, I went with french.Rule number 1 : A clean and well maintained system runs a lot better!Now all I do is defrag weekly or better, wich looks like a probable cause for your problem. It could also be you're virtual memory settings that needs some tweaking. I heard default settins are night-marish in certain conditions and aren't really appropriate for gaming.I also run AD Aware (an anti-spyware program) even more often as well as scan my frequently updated anti-vir software. Occasionnally found (and deleted) over 300 running on friends/family puters. That's tuff on resources and connections eh.Besides a defrag, virtual memory settings or perhaps a full scandisk in case of bad sectors, I'm out of clues for your specific problem.I hope this helpsQ!Flight simming since 1989 :)

Bonjour Quebec 01,Thanks for the reply.Since an earlier crash, I have been running a clean, well maintained system that gave no more trouble, until this one.Specs:-Microstar XP 1.9 GB256 megs DDRRAMGeForce 4 MX420 64 MB40 GB Hard DriveAlthough running a Spanish system, I get most work done in English without fuss and have more spyware than most folk. Have been using AdAware 6 for over a year, update it regularly and find it does a good job. AVG antivirus runs daily on auto and doesn
