Bug report:

Wasn't the new display refresh-rate automatic adjustment only be applied when Reclock AudioScript is used? Or else it might cause audio dropout after sometime of playback?

Display refresh-rate automatic adjustment? No. Reclock doesn't do and neither does MPDN's Reclock.
What exactly does ReClock do?

Still, what if ReClock is not using, in which case should MPDN NOT speed up or down to match the screen display rate?

If it's not in use, no it won't speed up or slow down.

I just installed Windows 10 (fresh build) and it comes with v353.62 installed for my NVIDIA NVS 4200M. MPDN's OpenCL NNEDI3 works fine with it. What version of NVIDIA driver did you encounter a problem with?

355.60, watch out for Windows 10's broken disabling of its third party driver updating..

Well according to this page, it was 353.62 that first had the problem: https://forums.geforce.com/default/t...5-/?offset=109

Perhaps they haven't actually removed the extension - they just haven't implemented it for their WDDM 2.0 drivers (NVS 4200M is a Fermi GPU so it's not running WDDM 2.0). So only users with Kepler or newer GPUs are affected.

That's the thought yeah. I just straight up reverted to what worked and disabled those updates and everything's been sweet as ever since.

Does DX12 work with the older driver?

Yes. Probably they will also remove it for Fermi GPUs when they introduce WDDM 2.0 support for it.
From what I've been told, the extension will not come back.
We still don't know why they did remove it, as AMD and Intel didn't.

Your D3D12 test works okay, dunno about everything else though.

Well then there's no reason why NVIDIA needed to remove the extension!

Yeah it's all a bit weird.. is it broken or removed? I think Manuel was looking into it, I might ask for an update.

BTW if anyone has their Windows 10 start menu stop working like I just did (also kills right click and left functionality on the taskbar)
then go here http://www.thewindowsclub.com/start-...pen-windows-10 and run number 4)
You'll need to run an elevated powershell
http://serverfault.com/questions/464...m-command-line

Bugger if I know what caused it.. Probably should've stuck with 8.1 for a bit longer.

I advise you to simply replace it: http://www.classicshell.net/

Since Windows 8 I'm using this Start Menu ... I tried Windows 10 Start menu for a couple of week and really ... I prefer the classic shell.

Yup, well aware of that one and Vistart too but will be running StartIsBack++ I think on my main machine when I upgrade, the new menu just doesn't have the same functionality. A little disappointing but hey I guess it works for the masses well enough.

I really thought it was an update I did, or the RAM speed I changed or the driver install I did. Real pain when you have one issue that springs up after you've made quite a number of changes recently and you just have to revert them all. Sure didn't help that I didn't have a restore point >.<

Anyway.. Windows 10.. not exactly a painless experience. I feel for the guys that have had their LCD's destroyed by what appears to be Nvidia's 353.62 driver. Fun times.

It is removed deliberately, according to ManuelG. A beta tester for Nvidia said it won't come back. Pretty certain, but not an official statement though! However, better bury any hopes.

Since OpenCL interop is or can be bugged on AMD as well (stupid PowerPlay bugs, especially with PCIe 2.0), I think it's not worth investing any time in new features that would rely on interop.

Shiandow's NNEDI3 SM 5.0 implementation works perfectly for me. GPU usage is a bit higher, but afair power consumption isn't.
GM200 probably can do 1080p60 64 neurons doubling via SM 5.0.

Btw: Could Asynchronous Compute of GCN be useful with DX12 for NNEDI3?

I'm working on another code path for SM5.0 NNEDI3. This may or may not be faster but I'll probably need the AMD owners to test it out since I don't have an AMD GPU.

Anyway I'll make another post when it's ready. It'll require a new version of MPDN too unfortunately.

Edit: Not sure about async compute, but from my early research into DX12, it would seem that interoperability with D3D9 had been dropped. If it's true then DX12 support won't be possible since most of the shader codes are in SM3.0.

Sounds interesting, I'm curious how fast it will be.

I don't know how much time it would cost you, but what do you think of a "MPDN Benchmark" tool?
It would run each shader as fast as possible and measure finishing times. I think it would be very beneficial for determinating the best video card for HQ HTPC purposes.

Ah, we've been down this road before. Love me some benches..

Got a good name for this too Zach..

Anyone else having a problem with the reclock script? It's causing, for me, a lot of dropped and delayed frames. I'm using SVP with it, might that be the problem?
