Using variable framerate mode (-fm vfr) which is the default is also recommended as this reduces encoding load. Ultra quality is also overkill most of the time, very high (the default) or lower quality is usually enough. +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.

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. You can automatically add this option if you run `sudo nvidia-xconfig --cool-bits=12` and then reboot your computer.\ -- cgit v1.2.3
