No need. The updated Nvidia driver was released Monday night at ~11:50pm Eastern Time (USA). Just update to 10.12.5 and, upon reboot, you'll get a Nvidia prompt to download and install the driver.Use this way to run NVIDIA web drive on 10.12.5.

The build number is 16F73 .
OK, please take all of this with a grain of salt as I am not a VDA/videotoolbox guru or anything, but:Wait a minute...
Why is the h/w accelerated playback not working?
What do the NVidia drivers do differently to the drivers shipped by Apple?
When I was watching a blu ray with mpv a few days ago, everything was working as expected and it didn't really hit my CPU any harder than before with my HD 7950.
OK, please take all of this with a grain of salt as I am not a VDA/videotoolbox guru or anything, but:
The NVIDIA Maxwell and Pascal drivers don't pass on the information that macOS needs in order to correctly see the GPU as a candidate for video playback, and since it's been a very long time since There's been a NVIDIA card in a Mac, the acceleration that would be available is limited (no support for HEVC, for instance).
When I was using a Maxwell card I fiddled around with some of the injector kexts that were supposed to get HW acceleration working but it always failed since I think it was trying to put the card in undefined power states. The short version is that macOS doesn't seem to want to enable accelerated playback on anything but the GPUs that model shipped with.
If you have a Skylake or Kaby Lake CPU and enable the IGPU in your system alongside your NVIDIA card, VDA/videotoolbox will attempt to use it as a video accelerator in "offline" mode, but this currently fails for unknown reasons. You can get QuickSync working but not video playback acceleration.
Luckily, this is only really a factor if you're playing high resolution and high bitrate HEVC videos. I tested the other evening and was able to play 4K 60fps H264 videos without slowdown but the HEVC versions maxed out my CPU and audio sync eventually broke.

Edit: I guess this thread is out of date, if a mod wants to move this post to the general nvidia drivers thread I don't mind
OMG! You guys caught me in a Senior moment! You are correct - I copied/pasted the wrong line from the MultiBeast Features document. I have corrected the OP. ("Dunno why this happened," he mumbled.)
So, the MultiBeast method for preserving NVRAM on some motherboards is:
Bootloaders > Clover v2.4k r4063 UEFI Boot Mode + Emulated NVRAM <--- page 6, MultiBeast Features doc
Thank you, iGV & mnsrit, for pointing this error out to me.
