Like I said, take a look at alpha distribution, not super complicated and a fair improvement in dithering. Adding another OIT, when a separate hardware implementation works with good performance, just so people can use it for backwards compatibility, just doesn’t seem productive. Even the good solutions can be so costly you’d not really want to use them on systems that don’t have Raster Ordered Views as it is, or even use them on those systems regardless.
When I say “expensive” I mean “we rendered it on a 1080 ti and it still took up 12ms on a resolution equal to half 1080p” expensive. Again, that’s a good, very recent OIT implementation: KIT - Computer Graphics - Publications . It’s just not useable.
