# 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`.\

Getting the texture of a window when using a compositor is an nvidia specific limitation. When gpu-screen-recorder supports other gpus then this can be ignored.
Remove dependency on glfw (and glew?).
Quickly changing workspace and back while recording under i3 breaks the screen recorder. i3 probably unmaps windows in other workspaces.
Remove hw_get_frame as it creates a new cuda device ptr which we dont use!
