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/nvencodeapi64.1337` against `C:\WINDOWS\system32\nvencodeapi64.dll` and `win10_x64/$latest_geforce_version/nvencodeapi.1337` against `C:\WINDOWS\SysWOW64\nvencodeapi.dll`.

A video tutorial is also available. Credits to designator2009. (*Covers older patches. Now we probably don't need to autorun executable if x86 library patch applied*)
