NVEnc patch not working whilst installing

[C0D3 M4513R]

When I tried to install updated Nvidia Drivers (love this tool for making those expert tweaks so simple) I noticed a new option to Disable the artificial NVENC Steam Limit, via a patch.
When I select the checkbox for that, the patch

535.98 / GeForce / DCH

is automatically selected.
When I then configured all things to my liking, I hit Next.
I am then immediately hit with this error, in a seperate Window:

Error applying NVEnc patch: nvencodeapi.dl_ not found

I have managed to get this error, by simply doing the following:

1. Install best driver for my hardware
2. Next (Driver Version)
3. Next (Components)
4. Check "Show Expert Tweaks"
5. Check "Apply NVENC Video Encoding Session Limit Patch (Experimental)
6. Next (Installation Tweaks)
7. Observe the Error described above

I am using NVCleanstall v1.15.1.

Actually seems like this is a known problem:

Dev - 535.98 NotWorks (-200Mb from NV setup in new release)

I used NVCLenStall on this new verion, but it won't work, so i used 3DGuru instead this time (https://forums.guru3d.com/threads/535-98-clean-version.433367/) Dev, know the NV setup has lost 200+ Mb in this version !!

----------------------
I had a little look at the files and the patch being applied.
The patch below does not even apply to the file that is being downloaded to "%TMP%\NVCleanstall\Display.Driver".

nvidia-patch/win/win10_x64/535.98/nvencodeapi.1337 at 3358c5d92e61d42c1557432e82ccda445d3fa082 · keylase/nvidia-patch

This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs. - keylase/nvidia-patch

github.com

------------------------
Okay, so I "just" needed to subtract "0xC00" from the offsets listed, because https://github.com/Deltafox79/Win_1...60ad02133eafca011/Win_1337_Patch/1337.cs#L150
And then I could apply the patches manually.
-------------------------
I applied the patches according to https://github.com/keylase/nvidia-patch/blob/3358c5d92e61d42c1557432e82ccda445d3fa082/win/README.md (so just download the Win 1337 Patching utiltity and apply the 1337 patch files to their binary couterparts)
-------------------------
Okay, so it seems that manually applying the patch, not selecting the "Apply NVENC Video Encoding Session Limit Patch" checkbox works.
I assume this is a simple typo somewhere....

Not sure why it's still not fixed, even though it was reported previously...

Also seeing this issue had to do it without the Session limit patch. Is W1zzard back from computex yet to fix?

I am getting the same error.



Manually patched driver works just fine

Manually patched driver works just fine

For me it seems it doesn't...

Spoiler: Before patching:

Spoiler: After having patched:

The error changes a bit meaning the patch changed something, but the test still ends in an error.

Tested it with the 536.09 DCH (Hotfix) & 536.23 DCH drivers, always the same conversion error in the end.

Problem found .. in the past NV shipped nvencodeapi.dl_ as compressed files, now they are shipping the uncompressed .dll files. NVCleanstall is always looking for the .dl_ file. This will be fixed in next release

Edit: Please test the attached build and feedback

Works great!

I didnt get this error when using with 517.40 studio drivers paired with NVCleanstall 1.16.

Ahh its the fixed version.

v1.16.0 (June 19th, 2023)​

• Added support for disabling Ansel
• Added a new install action "Copy Folder", which copies the NVCleanstall output directory to a folder of your choice
• Fixed "auto-accept unsigned driver warning" not working on Windows 10
• Fixed crashes on systems with English (United States) culture settings and decimal separator set to a value other than '.'
• Fixed NVEnc patch not working on newer driver versions
