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.\ @@ -139,7 +138,7 @@ Some linux distros (such as manjaro) disable hardware accelerated h264/hevc on A ## I have an old nvidia GPU that supports nvenc but I get a cuda error when trying to record Newer ffmpeg versions don't support older nvidia cards.
