Lightroom Classic 15.2 graphics memory leak

@AxelMatt In IT there is a rule:

Whatever the customer is paying for - we will develop and literally nothing is impossible these days.

When Adobe tests a new release, best practice is to turn on logging “everywhere” and react to those logs and the automatically running test results with change requests. Changes are then implemented.

Repeat.

When an acceptable level of defects, being classified as “cosmetic” has been reached - - then the logging is turned off for performance reasons. “Nothing is free”. Hopefully Adobe runs an automatic performance test then.

And you are right: PC’s are different in small ways and Adobe cannot keep on testing. However. And I will let everybody reading this “connect the dots”:

Release 15.2 of LRC (on my machine and a host of similar machines) keeps on munching up GPU memory until it eventually freezes. DavinciResolveStudio, the Topaz suite, Photoshop, PTGUI pro panorama stitcher run fine on their own.

BUT running any program like Topaz and PFGUI Pro that also uses GPU memory to speed up transactions - AT THE SAME TIME AS LRC - that combination results in these programs freezing too.

The next dots to connect:

LRC v 15.1.1 is almost stable, but not quite - it gobbles GPU but does not freeze.

LRC v 15.1 is completely stable and willingly releases GPU memory so I can export files for processing in Topaz and PTguiPro without having to exit LRC.

I simply do not need your opinion on whether this issue belongs to me or Adobe.

I am the customer. I pay for support and I get nothing.

Your main avenue of development these days is to link up to Ai companies and charge for tokens to process images there.

Your company is milking their cash cow without the possibility of logs because the information from logs would put the ball in Adobe’s court.

Your strategy is apparently to put the ball in my court and I am deeply disappointed about this zero-level of support. 

Just to remind ourselves: why did “everybody” choose Amazon? EXCELLENT customer service.

TEMU understands this and I have had excellent customer service from them too.

ADOBE has chosen NOT to use the Windows event logging system.

ADOBE could easily give us a script to execute, that would turn on logging so we could all get some data and support could have something to work with.

Instead ADOBE prefers that the customers try to figure out workarounds for half baked SW.

Done. Go back 2 versions.

So answer this: why am I paying every month for Photoshop & Lightroom to be updated to versions I cannot run on my excellent PC on a mid-tier ASUS Creator MB? 

Your SW says my NVIDIA Card is fully compatible, so???????????????????
