I think it uses VAAPI for AMD and NVENC for Nvidia, and saves it as H264
Comment on Steam Beta adds many more Game Recording improvements
thingsiplay@beehaw.org 2 months agoIsn’t it already using AV1 if the card supports it? The resolution thing is really weird, because I play at regular 1440p, but the recording is in 1080p.
Minimizes CPU usage of video encoding by using the dedicated video encoding hardware of your AMD or nVidia GPUs.

My monitor is ultrawide. It’s cropping off the top and bottom, fitting it into the horizontal resolution of 1080p, which is 1920. Vertical hence ends up at 804.
Why would the line about encoding on the GPU suggest AV1 is supported? Are your files AV1?
My card does support AV1, and I use it in OBS, but it also supports H264 and HEVC and even older formats. In OBS you choose whatever supported encoding you like.
Steam seems to just use H264 with no option to use something newer.

Yeah, I had a weird Gedanken-choke. You are right, it makes no sense to assume that from this.
