Probably they already have appropriate contacts with nVidia with the people responsible for OpenCL compliance.
Good idea (in principal), just add Apple too in that mail. They are on the same page as NVIDIA. And also not working. Then I'm sure they are compliant enough to be compliant. Just not the way we need them to be compliant.
But yeah, never bad to raise the voice of customer.
The purpose of this submission is to gain awareness and move up on the priority list a bug related to the implementation of OpenCL in the new Maxwell cards. This bug is causing an approximate 75% performance decrease in the charity work the Folding at Home (F@H) community is trying to do to study chronic diseases. I recently bought 3 GTX980's primarily for F@H as part of an Alienware Dell Desktop and I am saddened to hear of my mistake in not knowing about this major bug beforehand.
The head scientist at F@H claimed you were "working on this bug" here:

We don't have any location to officially express our demand for this bug fix. I've attached my msinfo in case you wish to review. Thank you for your help!
Why not add some code that disables the troublesome projects for GTX970/980? Having a gazillion Maxwells running at half speed is bad for the project in general (=slower returns overall) - it would be way better if those GPUs ran other WUs at full speed. Let 680/780/780ti's run these core 18 units if they perform reasonably well.
...or adjust the point for core 18 until a fix is in place, so that it matches p9201.
Maybe this is nvidia's fault in the end, but it's not like YOU cannot do anything to improve the situation. Stop waiting for the darn driver and do something useful that makes a difference NOW! Change the points, or "ban" core 18 from Maxwell GPUs. I'm not a coder, but this must be a rather simple task (alot simpler than fixing the driver!).
What you describe has been debated since the problem was first recognized in March.
The decision was made to release the WU from beta despite not having a resolution of the known problem.
I could link you to a dozen threads, but your best bet(in theory) is to participate here:
Hardware configuration: Intel i7-4770K @ 4.5 GHz, 16 GB DDR3-2133 Corsair Vengence (black/red), EVGA GTX 760 @ 1200 MHz, on an Asus Maximus VI Hero MB (black/red), in a blacked out Antec P280 Tower, with a Xigmatek Night Hawk (black) HSF, Seasonic 760w Platinum (black case, sleeves, wires), 4 SilenX 120mm Case fans with silicon fan gaskets and silicon mounts (all black), a 512GB Samsung SSD (black), and a 2TB Black Western Digital HD (silver/black).
From info from having read other people's reports: The latest v.4 of the core_18 seems to run okay on all driver versions, but runs best on Maxwell cards with Win drivers 347.xx and above, and Lin drivers 346.xx and above (which support CUDA SDK 7).
