How resource heavy is LIV?

LIV's performance cost is directly related to the game's cost. LIV renders another viewport, then once more for the foreground (where it will only draw pixels between the player and camera). It's about as optimized as we can get it while compositing the result outside of the game.

You might find that LIV just puts the game over its frametime budget, making it feel significantly worse, which is why we advise anyone filming with LIV to lower the HMD's render resolution in order to get a smoother result overall. This will not affect the resolution of the LIV output as LIV captures footage from its own camera, rather than from what your HMD sees.
