Lightroom Classic 8.4.1 to 9.0: Graphics acceleration has been disabled

After upgrading from LR Classic 8.4.1 to 9.0 graphics acceleration has been disabled on my MacBook Pro with an AMD Radeon HD 6750M graphics card

The requirements for graphics cards have changed, you now need a card with Metal support: https://helpx.adobe.com/lightroom-classic/system-requirements.html

... I see, but Photoshop 2020 IS supporting graphics acceleration with the dedicated graphics card on my system - even the advanced mode of graphics acceleration. I remember very clearly that originally the previous version of LR didn't support my graphics card either, yet a few weeks or months later an update of LR again supported graphics acceleration of this card!

I get what you're saying, but Ps & Lr are different programs running different code.  Just because Ps still has code that supports your GPU doesn't mean Lr does or will in the future.

And the reason it stopped and started working for you before is because this change was in the works for Lr 9, but mistakenly slipped into 8.4.  8.4.1 fixed the mistake.  It's a planned change in 9 though, so I wouldn't hold my breath expecting it to come back this time.  I don't recall where I saw it, but I believe Simon Chen has a post about it in one of these threads, if you do some searching.

Thank you for the explanation. However, as a very long-time customer of Adobe products, I am now inclined to answer: If the developers of PS can make this graphics card work in advanced mode in the latest and greatest version (2020), why would the developers of LR 9 be unable to do the same (whatever the code necessary)?

In my view, this is a matter of having the *will* to work on it, and not a matter of it being technically impossible.  

I won't be holding my breath. I will switch to other software. Not because I want but because Adobe forces me to.

Adobe's not forcing you to do anything. Lightroom still works, it's only the acceleration that doesn't, and on that level of graphics card, it wouldn't have been a big advantage anyway.

OpenGL is deprecated by Apple. It's dying. Adobe's just moving with the times. Photoshop is sure to lose support at some point too, it just hasn't happened at exactly the same time.

Of course, that is a matter of perspective. Yours versus mine. Of course, I am forced by Adobe to switch to other software, as the current version of LR no longer fully supports my graphics card whilst PS 2020 (!) still does just like software similar to LR. LR still works... sure... but it doesn't work like it worked before. Come and see for yourself how SLOW a very, very simple operation like zooming in and out on a 24MP (!) photo now is in the Develop module... Ridiculously slow.

What is dying in the Apple stores, is fully alive and kicking on my MacBook Pro. I am eco-friendly and don't buy new hardware every single year to "move" with the times. The times are calling for a radical new approach: keep alive what is alive and don't kill hardware that is a few years old.

I didn't expect any other answer from Adobe fans. Just don't expect me to "move" with the times. I am a very poor visual artist (read: fine art photographer), and I simply cannot afford nor do I want to afford new hardware every single year. Like I said, I am switching to other software.

I'm not trying to fuel an argument, but you're talking in generalities that don't add up.

A car (Lr) and a truck (Ps) from the same manufacturer (Adobe) both use tires (GPU).  It might be technically possible for both vehicles to be designed to use the same tires, but differences in their build and purpose would make that totally illogical to do.

Ps & Lr's code base isn't the same.  How Ps and Lr use the GPU isn't the same.  Just because some old hardware is still supported in one has no bearing on the other, and just like Victoria said, it's probably just a matter of time before support is dropped in Ps too.

That's a 9'ish year old GPU.  It's had a pretty good run, but to expect new versions of software to support it in perpetuity isn't terribly realistic.

You haven't read my latest reply.

First: Of course, the code is different between LR and PS. Of course the developers are also. But one could reasonably expect that LR developers are able to do the same thing as their PS colleagues: adapt software to hardware, and not vice versa... Generalities? Or logic and common sense?

And second: What is old is not dead. What is old and still functioning perfectly well with other software but not with LR 9, will not make me go and buy very expensive new hardware but will make me (and I gather 99% of all photographers with me) buy much less expensive other software similar to LR.

I can't afford a new computer which costs over 3,000 euro. And I'm not going to throw away (hello eco-friendliness!) something which is not broken, functions perfectly, and very fast also, with all other software, including PS 2020. The logical thing to do is to abandon LR 9 and go to other software. I suppose I'm not allowed on an Adobe website to name those other software... which uses my graphics card as though it was new, like it should. Not everyone, especially not in Greece, can afford new hardware every year or two. This is poor Europe, not the rich US.
