P: Add 10-bit/channel color display support

Add 10-bit/channel color display support.

Hi Stefan,

thanks for the correction, indeed, it seems like 10-bit has been unlocked in the consumer drivers, that is great to see. We need to see at least one major raw image editor to jump the ship and I am sure the rest will follow soon. It would not surprise me all that much if the support is already there, just "hidden" waiting for wider adoption of 10bit workflows.

Skippi,

Geforce cards do have 10bit/channel output (also for OpenGL) since at least a year or so. You don´t need a Quadro for that anymore. Even my old GTX 970 is able now to output 10bit/channel in Photoshop, which I can easily see and test. It´s night and day compared to 8 bit/channel. My new RTX 3060 can do it, as well.

But I support the request for 10bit/channel output for LR and ACR. Although the display dithering does a remarkable job.

What do you mean by "Photoshop support of the 10-bit workflow also did not improve significantly if at all." What should be improved?

Yes, happy anniversary,  dear feature request. 10 years, that asks for a big fat cake, at least as big as the middle finger Adobe is giving us all this time (not that I am surprised).

But on the other side, during those 10 years, has really anything changed?

AMD and NVIDIA are still unable to make up their minds whether they should fully unlock 10bit output on consumer cards (GTX/RTX/Radeon/Vega). They came up with these half-assed solutions such as OK, maybe we enable 10bit for DirectX (looking at you, NVIDIA), or, let's give this new checkbox that will not do anything, but you would not really notice anyway (AMD).

10bit HDR movies/displays should be the driving force, but card manufacturers are still unwilling to give up their Quadro/RadeonPro exclusivity and are just making the whole situation even more confusing to all, but expert users. I don't believe developers are happy about this either. Photoshop support of the 10-bit workflow also did not improve significantly if at all.

I am not whining, I am just stating the facts as they are.

Again, happy 10-year anniversary everyone! Live long and prosper, so that one day...

This request is 10 years old and still no proper response from Adobe beyond "Too bad, live with it".

This is not rocket science, it's coding. it's not too hard. It's not too expensive.

Our monthly subscriptions should have more than covered to cost to get this simple thing done. I'm pretty tired of excuses.

PS - I appreciate the detailed technical discussions below. Still, Let's get the job done, eh Adobe?

Yes, please add 10-bit per channel color display support. All my hardware and other software is at least 10 bpc, just not LR. That's a big flaw!
