Roblox | OBS Studio vs Roblox's Built-in Recorder
Roblox has a built-in screen recorder that, though gives good audio, doesn't maintain video quality. OBS Studio has solved that problem. This is a comparison between the two programs when you play your Roblox ga- I mean "experience". Roblox please update your recorder.
