AA/COF curiosity

Featured Replies

Noticed something very curious with the new HJG 707.... Had a bad case of the "jaggies" on that aircraft... I've always used the default AA in COF, since forcing it opens another set of issues. And I started thinking--some aircraft had AA applied quite well, and others didn't. So I opened up the bmps of those which worked vs. those which didn't, and found that 32-bit textures don't AA, but DXT1/DXT3 textures do.....The flip side is that 32-bit textures take less time to load than DXT1 or DXT3... That blew me away, since 32-bit textures are quite a bit larger, especially vs. DXT 1. It makes me think that the load time is also related to the AA being applied.In FS2002 on my rig, AA gets applied regardless of the texture type.It's pretty easy to convert textures from 32 bit to DXT1/DXT3. Visual quality isn't that bad either--I converted HJG's textures to DXT3 and the improvement in AA more than offset any perceived loss of texture quality. But I am curious, especially in regards to fellow Nvidia users, whether the default AA in COF can handle 32-bit textures with the latest set of drivers, or whether users simply choose to force AA and ignore COF's defaults altogether. Early on it was noted that COF's AA caused poor performance, but I haven't noticed that when it is applied...

The textures don't have mips. Textures without mips don't alais properly on my rig and I run 4xAA & 16xAF. As I do with all airplanes, I converted mine to DXT3wAlpha and the DXTBmp program automatically adds mips back. They look much better with mips and run better. They're very nice aircraft; but I noticed they are a bit harder on framerates. I usually get 70-80 fps panning around an aircraft. With the HJG707s, I only get 40-50 fps panning around em'.

My DXT1 conversion didn't have mips (and the 32 bit version didn't as well), but still the AA still applied to the DXT1 conversion. I used Imagetool to convert and saved the revised bitmap w/o mips...HJG's 707 doesn't hurt my fps that much. Right now, the worst offender in that area is IFDG's A320 in spot view... Don't know why, but I suspect it is a high poly count and low system on my side. The Air China variant of the 320 is another where I've changed the 32-bit fuse texture to a DXT 1 format texture, which is my favored format if there's no alpha channel defined...-John
