That and the game can flag frames that are too different (camera cuts) to mitigate this problem.
What the game supplies is the current frame + motion vectors, but the framegen bits take over how the frames are displayed onscreen. This is where the extra latency comes from, at worst you are seeing one true frame behind what the game is rendering, while the presentation layer generates the intermediate frame(s).






I wish they weren’t so expensive though.
IMO the biggest incentive of all is that the battery exists for the life of the vehicle and can be recycled at the end (the lithium inside does not disappear!), vs the gas which is literally burning money away.
