I found that the stuttering is caused by the constant loading/unloading of textures by your video card.I converted all my texture files to DXT3, and installed the "resized" autogen and taxi-way files from avsim. There is almost no visual difference, and now i have ZERO stutters, even at busy airports such as JFK or LAX. Take a look at this screenshot...taken at JFK. My framerate is staying high, and there were no stutters.there are at least 10 big planes in this shot, including polygon heavy 747s...but no fps or stuttering impact.http://fengzhudesign.com/fs2004/fs9_ai_13.jpg-fz

What are these files you installed?

Hi,When you say >>>I converted all my texture files to DXT3,<<< do you mean you opened the files properties and manually converted the title to DXT3?eg from: waves.bmp to waves.dxt3:-roll Andy.

Hi Yak Yak Looks a bit like London Heathrow Terminal 4 to me !! regards Jim

No you can't just rename the files, you need a program called DXTBMP to convert the textures to dxt3 format. They still have a .bmp extension.

Thanks for that info about the DXT textures. I d/led the replacement autogen from the earlier post,backed up the textures and tried it. I altered the scenery complexity---http://forums.avsim.net/user_files/147094.jpgand that seemed to make a difference of 6/8 fps from 6 to 12 or so but it is still pretty poor.Oh well, lots of other places to fly over.Andy.
