Differences between syncs for response times

[Justin023]

Hey yall I am looking for some opinions about monitor/GPU adaptive sync.

I am looking at getting an RX 9070XT tomorrow or when I can. I currently run a 2080 Super.
But I was wondering about G-sync vs Free sync vs no sync at all?
I like to play competitive shooters and want the fast response time I can get. 
Then there is like Nvida Reflex. If I go AMD will I have more input lag?
No quite sure. I tried doing some research but I didn't have too much luck. I believe g sync and free sync are equal.
But my main question is will I have more input lag by going to AMD GPUs?
Thanks Chiefs

My fortnite playing buddy swears by no sync

He tested using some software. Aimlabs? Something.

Nah it's VRR it may depend on game, fps range and individual what they may prefer. You won't have more input lag, also not all games even support these techs but more popular ones do. There's anti-lag in driver in general for games and some games have a anti-lag 2 in game settings to enable as extra, like CS2 for example as fps game.

But if a game were to support Nvidia reflex and not an amd equivalent would there be an advantage to having the Nvidia card?

Not really, as such games would already run fairly high fps where these things have less of an impact. CS2 ran fine without any tech and with anti-lag and later anti-lag 2 really as the game runs so high fps wise the timings are tighter so more of a use is more graphics heavy scenarios and kinda in some games that are not well optimized can help. But for example games like CS2, Dota 2, Apex Legends have AL 2 which is the tightest feature input response wise.

Thank you, okay. With the research and from what you all have said I realize that I probably won't notice it at all. But On a technical standpoint nvidia provides a better compatibility for there services which could lead to fast response times or is nvidia reflex and other similar service bogus? 
Or what do think?

The tech is not bogus, both provide it and works well in situations when it's needed, it synchronized CPU and GPU communication and rendering pipeline basically so that input feels nice. But this is much more noticeable in single player games, graphical demanding games like where GPU has very high usage. For sure it's nice to have it for online games there, but having higher fps in general will be more important anyway and something you notice way more.

Okay, thank you for your input.
Yeah I know that part is not bogus for sure but sorry I failed add context. But the context is just the response time. Like for example if both computer were the exact same build one amd and one nvidia both ran perfectly at 300 FPS. With that context would one even at all have a better response time due to its own proprietary hardware or software.

Maybe some difference there would be if that game would only offer the option for one brand but nothing that would be a deal breaker really I've tried to see in such scenario and not really something to worry. Both do the same thing just different name. At lower fps and GPU bound situations there's a more noticeable difference, those being more single player games right. With higher fps the response is tighter in general and GPU is never really pushed in such games, so it becomes more nice to have than need. Higher fps, better 1% lows and consistent performance will improve experience more.

Okay, thank you again.

For the absolute best response times you should run no sync and enable Nvidia Reflex or AMD Anti Lag. But tbh, if you're in the hundreds of FPS, there won't be a noticeable difference either way. At this point your own skill is the bottleneck, not the latency.
