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.
## Note about optimal performance on NVIDIA
NVIDIA driver has a "feature" (read: bug) where it will downclock memory transfer rate when a program uses cuda, such as GPU Screen Recorder. To work around this bug, GPU Screen Recorder can overclock your GPU memory transfer rate to it's normal optimal level.\
To enable overclocking for optimal performance use the `-oc` option when running GPU Screen Recorder. You also need to have "Coolbits" NVIDIA X setting set to "12" to enable overclocking. This setting is automatically installed if you run the install script (`install.sh` or `install_ubuntu.sh`), however if you use flatpak then you need to manually run `install_coolbits.sh` and then reboot your computer.\
To enable overclocking for optimal performance use the `-oc` option when running GPU Screen Recorder. You also need to have "Coolbits" NVIDIA X setting set to "12" to enable overclocking. You can automatically add this option if you run `install_coolbits.sh` and then reboot your computer.\
Note that this only works when Xorg server is running as root, and using this option will only give you a performance boost if the game you are recording is bottlenecked by your GPU.\
Obs! use at your own risk!

# 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`. But it's recommended that you use the flatpak version of gpu-screen-recorder if you use an older version of ubuntu as the ffmpeg version will be old and wont support the best quality options.\
Note that if you use the flatpak version then you wont be able to use overclocking unless you set "Coolbits" NVIDIA X setting (which you can do by running `install_coolbits.sh` and then rebooting).\
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.\
You can also install gpu screen recorder ([the gtk gui version](https://git.dec05eba.com/gpu-screen-recorder-gtk/)) from [flathub](https://flathub.org/apps/details/com.dec05eba.gpu_screen_recorder).
