1080p30 at ~10 Mbps isn't a low bitrate unless you are aiming for something very specific. Not to mention there is H.265 hardware encoder inside Intel Arc, although I have no idea about their quality. Nvidia seems to do a much better job in this area.

If you record a video game, I find that anything much lower really messes with the visual quality, especially if it portrays a forest scene or something with lots of detail like snow. Admittedly, you have to zoom in to notice and it's more apparent during fast movement, though VBR and other options seem to help.

The H265 encoder is also lovely, from what I've seen! Bigger file sizes, but a bit more software support in some places.
