Recently, I downloaded the all the resized texture from the avsim to make the flight smoother and gain FPS. However, FS2004 crashed to desktop when started to descend. Then I reminded that it had a note to use Render to Texture to avoid error. Then I used the Render to Texture and the FS2004 was not crashed anymore. Does it mean that I have to use Render to Texture, so the CTD was caused by other factors not related to the Render To Texture.Also, will the texture crash to Activesky's own texture

I assume you're using Chris's excellent HiFPS cloud set. Yes, the crash you experienced was most likely due to not having 'Render to Texture' on. I've had this happen as well. I couldn't say about the Active Sky testures, but I'd just leave the 'Render' option checked in the Display section to avoid any additional errors if you're going to continue to ues the HiFPS texutre set.I hope that was helpful.Have a good one!

Otherwise, FS9 will crash.To find out, whether your cloud texture is a DXT3, just try to open FS9/texture/cumulus01.bmp with MS Paint (or the Windows XP picture viewer). Both programs cannot load and display DXT3 bitmaps, so you will either get an error message or a "broken" looking image. If that's the case, the texture is in DXT3 format, and you need to run FS9 with the "render to texture" enabled.Active Sky allows both DXT3 and 32bit cloud textures and it will check your FS9.cfg and not allow you to install dxt3 textures w/o the render to texture setting enabled.
