This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs.
This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs. Also there is experimental NvFBC patch available which allows to use NvFBC on consumer-grade GPUs. It should be applied same way as NVENC `patch.sh`, except you have to use `patch-fbc.sh` instead.
Main target operating system is **GNU/Linux**, but for **Windows** support see [**win**](win).

This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs.
This patch removes restriction on maximum number of simultaneous NVENC video encoding sessions imposed by Nvidia to consumer-grade GPUs. Also there is experimental NvFBC patch available which allows to use NvFBC on consumer-grade GPUs. It should be applied same way as NVENC `patch.sh`, except you have to use `patch-fbc.sh` instead.
Main target operating system is **GNU/Linux**, but for **Windows** support see [**win**](win).
