Nvidia has actively been developing OSX drivers lately and according to the tech sheets any GPU that supports Open GL 4.0 has full support for Metal. However...

Metal isn't being used by the Finder (Netkas has tested this), it's still OpenGL based Quartz rendering. Preview app isn't going to be deemed important enough for Metal either and will still being using Quartz.

The issue I'm seeing with volumes of large files and Finder slowness has more to do with the system's I/O and file handling operations than graphics acceleration.
Your GPU is of a generation that is not even sold in any Apple product. So you can't draw any conclusion. Even if you think nVidia supports it fully, you can't know all the details. There's been many reports about issues with flashed or non-flashed graphics cards (even some that belong to GPU families that were sold in official Apple products), having problem in very specific areas like flash videos in safari, not working in certain games...

There's no issue here. I have been benchmarking the graphics performance in other apps during the beta stage. I know the Metal side of the driver hasn't been completed yet, but the GUI has been using Open GL during the beta stage anyway (unless you have Intel graphics).

And if you read my posts in detail I have run the same tests on iMacs too. The Finder in Yosemite and El Cap just can't generate thumbnails for large files in icon view, or it will generate some and then leave others.

Regardless, the operations I have mentioned above could be done years ago. Snow Leopard on a Core Duo did a better job.

Don't use the feedback assistant and instead report bugs at https://bugreport.apple.com

I doubt they would see it as a bug. They have simply dropped the ball in recent times. Look at the number of pro tools they have either dropped or simplified. Maybe they just don't care for high end creatives and thinks we should use that silly iPhone camera that they overhype every year. Or they conceded the battle for pro apps to Adobe and think we should just use Bridge for creative file management.

In response to the original poster's comments, I have been using El Capitan since the earliest betas. When one chooses to live on the technological edge, it is only natural that a few apps will break along the development road from early betas to final Golden Master. Thus, I was not surprised that both Bartender and cDock broke, and it seems that MAMP PRO may have been another casualty as well, as of DP8. However, both Bartender and cDock have since been fixed by their developers. MAMP PRO is a big question mark still.

Overall, I have noticed a marked improvement in stability between Yosemite and El Capitan. My experience has been that El Capitan has been quite solid, and I can appreciate the fact that Apple is taking the time to build up and reinforce what it gave us in Yosemite and earlier iterations of the OS.

If I were to complain about anything, it is about the rather drab GUI with its flat gray and light gray interface. It simply does not appeal to me. I am an old school Mac user since 1990, so I miss the bright colors, shiny bevels, depth, etc. But that's just me. :)

Just doing a test which I will publish along side my complete test in two weeks. Dropbox on iPad can display thumbnails and previews of large TIFFs in the cloud over a cellular connection faster than Yosemite or El Capitan can do with the same files saved locally on a user's desktop. :eek::confused:o_O
