What's the difference between DXT1 and DXT3? Which is best to use for AI textures for better framerates? Thanks.

DXT1 has no reflections, where DXT3 has, use DXT3 for AI textures, they are fine for this purpose.Also, you will save a lot of HDD space, and increase performance if you convert all of your 32-bit textures to DXT3, with minimal IQ loss.Dan.

DXTBMP is my preference, but many people also use imagetool.Google for them both and you will find themDan.

And you can get DXTBMP here: http://www.mnwright.btinternet.co.uk/index.htmwith a pletore of other graphic niceties :-)make shure you d/l and install the latest update of mwgfx.dll package needed for most of these tools.Hugo

Howdy,actually, there are two interesting threads about texture conversion as well as DXT1 vs. DXT3 in the PAI forums:http://www.flightsimmer.com/forums/showthread.php?t=15676http://www.flightsimmer.com/forums/showthread.php?t=30607Cheers, Holger

Wow, thanks for all the help to all who responded. That's why this forum is so great...people like you willing to help. Take care.

Hi, me again. I noticed that the program "GATraffic" has an nvidiatexture conversion program. Anyone have any experience with this one? Is it any better than imagetool and does anyone know if it converts to dxt1 or dxt3? Thanks
