That's the upper limit of what I think is safe to use with manual inspection.<br /><br />That test set is 89 MB BC7, 11.5 MB BC1, 11 MB BC3, 15 MB BC4<br /><br />(sizes of uncompressed BCN files)<br /><br />You're right that Kraken sometimes finds little compression on BC7, but it depends on the texture. There are several examples posted on the various pages that show that case, where Kraken (without Prep or RDO) gets over 7 bits per byte on BC7, very little compression until it gets some help from Oodle Texture.<br /><br />This particular set of BC7's has a bunch of normal maps that have big areas of flat normals, and some character charts where the whole texture isn't used. It's a real set from a shipping game in 2019.<br />cbloomhttps://www.blogger.com/profile/10714564834899413045noreply@blogger.comtag:blogger.com,1999:blog-5246987755651065286.post-65780392190216462992020-06-18T16:46:16.740-07:002020-06-18T16:46:16.740-07:00What was the lambda in the 127MB example?

And what about BC7, usually Kraken is having a hard time with BC7 but in this example, Kraken without RDO got 45% on average? I'm assuming it had just a few BC7 textures?Anonymoushttps://www.blogger.com/profile/15457885490995987083noreply@blogger.comtag:blogger.com,1999:blog-5246987755651065286.post-23766606959907583182020-06-18T15:34:03.457-07:002020-06-18T15:34:03.457-07:00The 30 MB savings on the particular test set that ...The 30 MB savings on the particular test set that I show results on there.<br /><br />We got 127 MB of uncompressed textures from a gain, covering a few characters, some models, and level textures.<br /><br />Those would have been 78 MB without Oodle (just zlib compression). That's the size a gamer would have downloaded.<br /><br />With Oodle Texture + Kraken that got down to 40 MB. 38 MB saved out of 78 MB, so almost 50%.<br />cbloomhttps://www.blogger.com/profile/10714564834899413045noreply@blogger.comtag:blogger.com,1999:blog-5246987755651065286.post-60086256188213468372020-06-18T14:04:03.637-07:002020-06-18T14:04:03.637-07:00I think there is typo in your text regarding the s...I think there is typo in your text regarding the saved data sizes for the games reaching 100 GB.
