Nvidia drivers patch for Windows
|
||||
================================
|
||||
|
||||
  
|
||||
|
||||
This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs.
|
||||
|
||||
Requirements:
|
||||
|
||||
- Any of following 64bit operating systems:
|
||||
- Windows 7
|
||||
- Windows 8
|
||||
- Windows 8.1
|
||||
- Windows 10
|
||||
- Windows Server 2008 R2
|
||||
- Windows Server 2012
|
||||
- Windows Server 2012 R2
|
||||
- Windows Server 2016
|
||||
- Windows Server 2019
|
||||
- NVENC-compatible GPU (https://developer.nvidia.com/video-encode-decode-gpu-support-matrix#Encoder)
|
||||
- Nvidia driver. Patch available for versions in [table below](#version-table).
|
||||
|
||||
## Step-by-Step Guide
|
||||
|
||||
1. Download and install latest Nvidia driver supported by this patch.
|
||||
2. Download latest [Win\_1337\_Apply\_Patch tool](https://github.com/Deltafox79/Win_1337_Apply_Patch/releases/latest).
|
||||
3. Save appropriate patch(es) from [Version Table](#version-table) using direct link to the patch (Right Click -> Save as...). Alternatively you may checkout repo using git or download it as ZIP archive and then locate corresponding .1337 patch file in `win` directory.
|
||||
4. Apply x64 library patch to corresponding file in `%WINDIR%\system32\` with the Win\_1337\_Apply\_Patch tool. File name of patched object is specified in first line of .1337 patch. If x86 (32 bit) library patch is also available, apply it to same file in `%WINDIR%\SysWOW64\`.
|
||||
|
||||
E.g, for 64bit Windows 10 running driver version $latest_geforce_version use `win10_x64/$latest_geforce_version/nvcuvid64.1337` against `C:\WINDOWS\system32\nvcuvid.dll` and `win10_x64/$latest_geforce_version/nvcuvid32.1337` against `C:\WINDOWS\SysWOW64\nvcuvid.dll`.
|
||||
|
||||
~~There are additional steps may be required for Plex and 32bit apps users. See [corresponding section below](#d3d11-and-32-bit-apps-encoding-sessions).~~ We hope this is obsoleted by new additional x86 (32bit) library patch.
|
||||
|
||||
A video tutorial is also available. Credits to designator2009. (*Covers pre-x86 patches. Now we probably don't need to autorun executable if x86 library patch applied*)

### D3D11 and 32-bit apps encoding sessions
|
||||
|
||||
This section is actual only for D3D11 encoders and earlier driver versions (before 440.97).
|
||||
|
||||
This patch for earlier driver versions (those which do not have additional 32bit library patch) wasn't covering 32bit driver libraries and for this reason 32bit applications were limited unless limit is not raised by some 64bit applications. But once usage limit was exceeded, it persists for all kinds of apps until system reboot. So, for example, you may once open 10 sessions with 64bit version of `ffmpeg` and limit will get raised to 10 for all rest types of apps until reboot. You may follow these steps to achieve this automatically and have all limits raised (assuming patch above already applied):
|
||||
|
||||
#### Method 1 (recommended)
|
||||
|
||||
1. Download and run [latest release](https://github.com/jantenhove/NvencSessionLimitBump/releases) of [NvencSessionLimitBump](https://github.com/jantenhove/NvencSessionLimitBump).
|
||||
2. (Optional) Add it to autostart programs.
|
||||
|
||||
By default this application raises limit to 32 encoding sessions. Credits to @jantenhove.
|
||||
|
||||
#### Method 2 (alternative)
|
||||
|
||||
1. Download 64bit FFmpeg for Windows: https://ffmpeg.zeranoe.com/builds/
|
||||
2. Unpack it somewhere.
|
||||
3. Get [`ffmpeg_null_10streams.cmd`](ffmpeg_null_10streams.cmd) from this repo.
|
||||
4. Edit `ffmpeg_null_10streams.cmd` and set executable path to real location of your unpacked ffmpeg.
|
||||
5. (Optional) Add `ffmpeg_null_10streams.cmd` to autostart programs.
|
||||
|
||||
**Bonus**: you may use [this AutoIt script](silent_bump.au3) from @wazerstar for silent startup of console applications bumping sessions.
|
||||
|
||||
Also you may use these methods to check if patch applied correctly and limit was raised. Use them when nothing works and you are in doubt.
