Horrible performance on latest Quadro cards

There’s an ABuffer OIT algorithm I’m putting in our main application and it gets reasonable performance on Quadro K2000 cards.
I’ve tested it on both the Quadro K620 and K2200 cards and performance is terrible (like it’s taking a driver software path or something).
I’ve submitted the bug here:

Now that I’ve verified that it’s also a problem on the K2200, it would be great if it the driver team could please take a look at it soon.

Thank you,
