Seriously guys? You might as well turn motion interpolation on your chitty low-end LCD.
a frame interpolation method that has access to engine information like the depth buffer and motion vectors can make way more precise and more informed guesses on how the next frame should look like.
and with DLSS specifically there's also a machine learning component that cleans up the image as much as possible.
It's not only fake as hell,
all frames are fake
if your game already runs at 60+ native fps on a PC with Nvidia reflex enabled (which is mandatory for DLSS frame gen) you have significantly lower input lag than 99% of console games.
adding a few milliseconds of lag with frame gen will still result in lower latency than almost any console title.
if you play at 120+ native fps with frame gen and Reflex, your latency will be so low that only an eSports player would notice the difference between native and frame gen
and visual artifacts all over the place, as expected.
these visual artifacts will be almost invisible to the naked eye if your base framerate is high enough.
on a flatscreen this can be preferable to the sample and hold persistence blur that all flat screens suffer from.
basically, if you play on PC, and you have a high end GPU, and you have a high end Monitor,
then frame gen has almost zero actual downsides but the upside of more fluid looking motion and less persistence blur from your monitor.
And +reflex without framegen = lower latency than +reflex with framegen.
Because framegen... adds latency?
yes reflex without frame gen is the lowest latency you can get.
however, 60fps native framerate with frame gen on top, and reflex enabled has SIGNIFICANTLY lower latency than the same game at the same framerate on console.
so if you are that sensitive to input lag, you better not play on console, as consoles don't have access to Nvidia Reflex.
God of War 2018 at 60fps:
PS5 = 112ms
PC + Reflex = 73ms
Frame Gen adds like 16ms of lag, which will still be far below console.
