DLSS, Reflex and input lag.

[Ellis_Cake]

Just a headsup; we didn't have these options on consoles but:

For minimal input lag, disable DLSS (it adds some input lag)
and consider enabling reflex + boost if you have the option.

This will ensure you have the least input lag before you go online and battle it out.

DLSS does not add input lag, DLSS 3 frame gen does.

It adds some ms to the latency even so. In VF every little counts.

hmm that might help me time the evasion 4 tutorial better ..

no it does not. stop spreading lies. the idea behind DLSS is that your graphic card renders the image at lower resolution and it then gets upscaled by AI, which in total is faster than your GPU rendering the thing at the final resolution. so in theory DLSS would actually have less latency because the frame rendering is done faster. BUT since this game is locked to 60fps there will be no difference in latency between DLSS on/off as long as your pc can keep those 60 fps in both cases.

Sigh. Input Latency/frame latency and FPS are _Different_ things.
you should look up frame latency, dlss and reflex - and read up on the small things that affects latency ever so slightly. Instead of going upset-rant.

Tacos?

Yes very true. Also disabling vsync can further reduce delay. Its better to set a fps limit if one wants in their control panel.

No they are correct and aren't spreading lies. The actual ai processing is the reason for the added latency and doesn't reduce latency like you mention. It's very small but like what was said is that every little counts in a game like this. Any sort of Ai post processing is going to affect latency and it's just frame generation that tends to impact it more significantly. Using different controllers, using different monitors and obviously components in your computer all contribute to latency from the very input pressed to what is on screen. As mentioned above, I noted even vsync is recommended to be off to reduce latency.

This!, thanks

To be clear dlss can reduce latency, I can not speak for this game because I couldn't play yet but DLSS does not automatically increase latency nor does it decrease it.

The real answer is, it depends.

not really..
reducing scaling below the threshold will reduce latency, where DLSS will guess what It needs to do and adjust..

Even in performance mode its still guesstimating in a game where every frame counts.

sorry, but you have no clue. and the other person who agreed so, too.
input latency means the time between input and you seeing the result on the screen. what factors into this are many things, like the delay of you input device to transmit the input, the response time of your display etc etc etc AND the amount of time a frame takes to render.
so if we are assuming a game has no hard frame limit but uncapped fps, then DLSS will reduce input latency, because it reduces the time it takes to full render a frame. thats why you get more FPS. if without DLSS you can manage 60 fps it takes one frame 16,6ms to render. if with DLSS you now get 90 fps, it now only takes 11,1 ms for a frame to render so now your input latency is reduced by 4,5ms. Yes, the AI up scaling takes some time, but it gives you more fps because having your GPU render at lower resolution + the time for upscale is faster than the time your GPU needs to render at output resolution. thats why you get more frames AND less input latency if the game has uncapped fps.
Now on to this game with a hard 60 fps lock: for a game like this it does not matter how fast a frame is rendered, as long as it is below 16,6ms to keep the 60 fps. what the game does is: it looks at the game state (including the inputs you made) every 16,6ms and renders a frame based on that, that is then stored and shown when 16,6ms are over. then the process is repeated. so as long as you can render the frame in those 16,6ms it does not matter if DLSS is on or off.
i hope you learned somehing.

as for people mentioning vsync and me mentioning DLSS frame gen. YES! those two add latency. Vsync does so because it buffers 1-3 frames (based on the buffer setting) so its 1-3 frames added delay. And DLSS frame gen buffers 1 frame because in order to generate the interpolated frame it already needs to know the next frame. so the added delay is 1 frame.

as i already explained above, yes naturally the AI up scaling takes some time, but rendering at lower resolution + ai up scaling is faster than rendering at native resolution. otherwise DLSS would produce less FPS and not more. and as i already mentioned yes, vsync and frame gen adds latency because of buffered frames, but i already said that about frame gen in my initial post. so you are partly wrong and partly repeating what i already said.

[Dokferr]

ZooL is right people. Framegen does add latency, but DLSS itself isn't.
Try to look at the image that compare the latency of native, DLSS2 perf and DLSS3 with frame gen.
