It's kind of weird to me that GPUs don't have planar textures now, I guess... maybe it shouldn't be weird to me, but it is?
@cmuratori Because GPU cores now always operate "planar" now, don't they? Ie., SIMD lanes are 16 or 32 wide R-R-R... etc., not R-G-B-A...

@cmuratori So it just seems weird that textures are still all about interleaving. What am I missing? -
@cmuratori Interesting question, paging@Simon_Fe1 :) - Show replies

@cmuratori planar like bit planes on Amiga? You're arguing it would be faster to upload the texture because it doesn't need to be converted? -
@sqaxomonophonen Well, not knowing any better, I would think it would be better for _everything_. - Show replies

@cmuratori Use compute for planar tex :) Rotated textures can require 4X memory accesses in worst case and probably blow N-way L1$ upThanks. Twitter will use this to make your timeline better. UndoUndo
