This will allow variable refresh rate to work when recording fullscreen applications. Note that some applications such as mpv will not work in fullscreen mode. A fix is being developed for this. # Performance When recording Legend of Zelda Breath of the Wild at 4k, fps drops from 30 to 7 when using OBS Studio + nvenc, however when using this screen recorder the fps remains at 30.\ When recording GTA V at 4k on highest settings, fps drops from 60 to 23 when using obs-nvfbc + nvenc, however when using this screen recorder the fps only drops to 55. The quality is also much better when using gpu-screen-recorder.\ It is recommended to save the video to a SSD because of the large file size, which a slow HDD might not be fast enough to handle.\ Using NvFBC (recording the monitor/screen) is not faster than not using NvFBC (recording a single window) with gpu screen recorder, in fact it might be a tiny bit slower. + # Installation If you are running an Arch Linux based distro, then you can find gpu screen recorder on aur under the name gpu-screen-recorder-git (`yay -S gpu-screen-recorder-git`).\ If you are running an Ubuntu based distro then run `install_ubuntu.sh` as root: `sudo ./install_ubuntu.sh`.\ If you are running another distro then you can run `install.sh` as root: `sudo ./install.sh`, but you need to manually install the dependencies, as described below. + # Dependencies `libgl (libglvnd), ffmpeg, libx11, libxcomposite, libpulse`. You need to additionally have `cuda` installed when you run `gpu-screen-recorder`.\ Recording monitors requires a gpu with NvFBC support (note: this is not required when recording a single window!). Normally only tesla and quadro gpus support this, but by using [nvidia-patch](https://github.com/keylase/nvidia-patch) or [nvlax](https://github.com/illnyang/nvlax) you can do this on all gpus that support nvenc as well (gpus as old as the nvidia 600 series), provided you are not using outdated gpu drivers. |
