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.
