Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Sure, no problem. As I said in my edit
that will be valuable information.

Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Okay, did the clean install of the latest drivers and a reboot after.
DGIndexNV and the other programs show the same error again.
-> so the solution again seems to be downgrading the drivers. (will test the drivers down to 369.30 to see which is the last working version)
btw: Thanks a lot for the support.![Very Happy :D](./images/smilies/icon_e_biggrin.gif)

Ps.: will report the last version that works here so that other users that might run into the problem don't have to do the testing again.

Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Cool, that will be useful information, although it may not be the full answer because the latest driver works fine for me with my GT620. I prefer not to have to install the 950 because my Win10 system is physically a little fragile and I don't like to make changes unless absolutely necessary. Anyway, I don't have the right PSU cables on hand for that system.
Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Okay, that was fast.
Just switching to the previous version 376.33 solved the problem.![Smile :)](./images/smilies/icon_e_smile.gif)
Issue is solved then.![Smile :)](./images/smilies/icon_e_smile.gif)

Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Sweet, thanks Selur. They probably just accidentally omitted a DLL or something, although a more serious screw-up cannot be ruled out, e.g., changes to WDDM 2.0 support for later cards.
Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
You could try this hotfix driver, too.
http://nvidia.custhelp.com/app/answers/detail/a_id/4378
According to this, it reverts behavior to the level of the previous 376.33 version, so it may fix your issue (or not).

It's obvious that driver version 378.49 had a lot of issues. The PhysX issue is mentioned too.

Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
tried the hotfix drivers, issue is still present.
So I'll stick to 376.33 and test the next version.

Re: "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Sounds good, Selur. Thanks for your testing and I'm happy you are back in business.
BTW, you can tell Windows update not to include 3rd-party drivers. I do that and don't automatically upgrade. I upgrade only when I have to: to support a user or to get a feature I can't live without. Ann Landers definitely got it right: "If it ain't broke, don't fix it."

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
I normally try to keep my drivers up-to-date since in example NVCEncC often only works properly with the latest drivers installed.
Hopefully NVIDIA will fix the issue with their drivers in one of their next updates.![Smile :)](./images/smilies/icon_e_smile.gif)

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
I'm getting exactly the same behaviour as Selur, his first post describes exactly the same steps I took trying to get around this including the 64-bit exe working but when combined with the 32-bit DLL, the "CUDA error!" green screen. I'm hitting all the same error messages in all the same scenarios.
My system is a little simpler in that no other GPUs are invovled, my specs:
GTX 980Ti (driver 378.66 released Feb 14th)
Win 10 Pro x64
i7 5820k (so no iGPU)
DGIndexNV 2052

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
-> downgrade your drivers (last working were 376.33 )
Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Hi Selur, yes I saw that workaround but my PC is mainly for gaming so I'm not going to be languishing on old drivers for very long. What are the downsides of avisynth 64-bit? I just want to run some encodes in Hybrid
without having to stick to outdated GPU drivers.

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
a. You can't use Avisynth 64bit in Hybrid
b. Avisynth 64bit is even more unstable than Avisynth MT (which is one of the reason for a.)
c. lots of filters are not available for Avisynth 64bit (which is one of the reason for a.)

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
As are we all. I'm still languishing on 326.80, since they refuse to fix bugs for old cards.
Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Yes, and OpenCL support is deficient for older cards too. Who can blame them, though, it's a CUDA versus OpenCL battle. Meanwhile, Vulkan rises to the fore. Everybody is going to concentrate on the cutting edge.
I just make a stable system that meets my CUDA/CUVID needs and then leave it alone. If you are a gamer that needs latest drivers, etc., well, maybe you can afford two systems. If not, play stupid games, win stupid prizes.
It's not unknown for things to get fixed, so keep the faith. Until then, you can only use drivers that work.
BTW, Avisynth+ 64 works fine for me.

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Small follow-up: today I was prompted by GeForce Experience that a 'GeForce Game Ready Driver' was available (version 378.66; release date 2017/02/14) and since I'm always a bit curious I installed it and like I suspected DGDecNV doesn't work with it so back to 376.33, till the next driver release.
Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Thanks, I was just about to try that version.
Just a note for those that haven't read the whole thread: It's not just DGDecNV that fails in this use case with these new drivers; the nVidia sample applications also fail.
I think people should try to upgrade to Pascal GPUs where possible, and leave the past behind. Yes, Maxwell is not that old, but it is what it is.

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
NVCEnC also fails with that the 378.66 driver version,... (upgrading to Pascal isn't planned here for a while,.. not prepared to shell out the money needed for a GeForce 1080 to replace my 980Ti; especially since my whole system is watercooled which adds another 100+ bucks for the cooler,..)

In this case, the bleeding is probably from your bank account. GPUs are expensive. ![Wow :wow:](./images/smilies/icon_eek2.gif)

Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
Yes, but band aids are cheap
Re: [RESOLVED] "ERROR: Failed to create CUDA contex" - DGDecNV 32bit
I don't call $139 expensive. With Volta not due for desktops for at least a year, 1050Ti puts you on the bleeding edge for at least a year. What's not to like? 38 cents a day. C'mon, you blow much more at Starsucks.
I pulled the trigger on a second 1050Ti to upgrade my 980X machine. I took it out of the giant tower case to put it in a smaller case I had left over. I'm saving my big tower for the next machine. I put it in the tower only because the CPU cooler was too tall. So I ordered a low-profile 1366 fan.
Maybe we should have a desktop HW/SW subforum? Sure, why not.
