I think your conclusion could only make sense with vsync on. Otherwise, doing something could only be slower than not doing something.

- HumanOstrich 3y agoYou're oversimplifying things to the point of being willfully ignorant. Yes, of course "doing something" could only be slower than "not doing something". But we're talking about 2 somethings involved in generating individual frames. 1) Generating a big slow frame or a small fast frame. And 2) Not doing upscaling or doing upscaling. Generating a small fast frame + upscaling CAN be faster than generating a large slow frame without upscaling, so it is possible to get the same perceptual visual quality at a higher FPS. Again, this is an intra-frame operation. Latency is introduced independently of frame generation rate by frames being queued or delayed in the pipeline. For example, the new DLSS 3 frame generation feature needs 2 complete frames to generate the one in between, so the first one is queued, and the remaining 2 are delayed. Delays in processing inputs can also be a big factor in latency. Since vsync happens outside of individual frame generation, having it on or off doesn't matter for our argument. I found plenty of results in Google demonstrating that upscaling doesn't affect latency, or at least not enough to be perceived by a human.
