I'm not sure of that because yesterday with an old nvdia driver (327.23) I use OpenCL and I NNEDI3. The GPU even in 64 neurons was fully loaded. I couldn't use with 128 n....
NNEDI3 is recently introduced to MadVR v0.87.10. It is basically a super high quality upscalling engine which demand more and more hardware power GPU as well as CPU. I have recently upgraded my HTPC by including Asus GTX 750Ti and Core i3 4th gen. CPU (4130) and corsair vengeance 4gb ddr3 RAM. It works perfectly for the following settings --
Chroma upscalling > NNEDI3 > 64Neurons;
Luma/image upscalling > Jinc>3 taps>AR;
Image doubling
NNEDI3 double luma resolution > always > 32 Neurons
NNEDI3 quadruple luma resolution > always > 32 Neurons
Luma/image Downscalling > Cutmull-Rom > AR+LL
Rendering > Dithering > Error Diffusion - Option 1
Artifact removal > both Medium.
As you mentioned, if you want to use 128 nurons or more then you require even more powerful GPU which can better and faster calculate Open CL and Direct Compute II features of your GPU. Basically modern HTPC powered by MPC-HC/MPC-BE + MadVR v0.87.10 + LAV Filters + ReClock is required very powerful Gaming DirectX 11 GPU (One or more) which is more capable of using OpenCL and DirectCompute 5.0
And of course these settings give me the highest picture quality and top class upscalling of SD and lower HD content. One word I can say now 'WOW'.
Current nvidia drivers have some bug which create some problem using OpenCL and DirectCompute 5.0 but the older nvidia driver 327.23 don't have such problems, it works nice....What were u trying to play. and why would you use old nvidia drivers.
