## 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 (or nvenc, which uses cuda), such as GPU Screen Recorder. This can affect game performance.
|
||||
GPU Screen Recorder installs an NVIDIA profile on the system (`~/.nv/nvidia-application-profiles-rc.d/10-gsr-cuda-no-stable-perf-limit`) to get around this issue but this requires a relatively
|
||||
new NVIDIA driver version (~580). If you have an older NVIDIA driver then you can choose to record with vulkan video encoding instead as it doesn't have this issue.

|

|
||||
You can use vulkan video encoding by adding `_vulkan` at the end of the video codec option, for example: `-k h264_vulkan` or a full command example: `gpu-screen-recorder -w screen -k h264_vulkan -o video.mp4`.
|
||||
Vulkan video encoding in GPU Screen Recorder supports `h264`, `hevc` and `av1` (along with `hdr` and `10bit` options), assuming your gpu drivers, ffmpeg and vulkan is up to date.
