Could you give your PC specs, specifically your CPU and GPU?

You're probably getting frame drops with remote play due to internet issues and the app as a whole being bad.

Unless your PC is very old and cheap, it should have no problem recording from a capture card. You can buy cheap ones from Amazon for ~$20 which should work well, just remember to get a HDMI splitter if you do buy a cheaper capture card with no passthrough.

@Pear lmao what?

@Breadn_ Some spambots copy-paste posts from the speedrunning reddit before editing in the spam link, so the posts will be on topic and go overlooked.
