pointblank, those really do look excellent and I thank you for the reply and the links. :-)
It's been my experience though that saving what starts as a jpg out as jpg always results in unacceptable loss, regardless of how good the texture was to begin with.
Now if you start out with a bmp for example, and then save it as a maximum quality jpg, the file compression will be great and the texture loss will be virtually unnoticeable. However, if you save out that jpg you just made as another jpg, even at maximum there will be noticeable degradation.
So I really do want to find some high quality textures in bmp, png, psd or whatever other no-loss format. I have texture folders that are exceeding 500 MBs because I'm saving all my texture edits out as png to avoid the degradation, and those files are 8,12,15 MBs each, when they could be a fraction of that if I didn't have to use png.
It's also worth mentioning that a 15 MB texture file will use far more GPU memory as well as far more RAM when rendering than a jpg of the same texture.
