G-Sync & Reflex Low Latency - How To Use Both 

The complexity with how all these features work together in tandem is really confusing. Just fiddling with it myself, as a developer in a different field, has my head spinning at how many variables there are at play. And as an end user its almost impossible to figure out what's happening at a granular level, at least, without resorting to a video like this. So Reflex is a welcome step in the right direction to give the end user more control over the experience they themselves desire from their machines.

yeah i did see your comment it was a good idea!

same!

idk how much more simpler he can put it.

Have always heard when enabling G-Sync that you should always turn v sync on in NVIDIA control panel and NOT in game. But now this video is saying otherwise....

@@supermanlift i have G sync on and enable it in game and it lowers the ms by 3-4ms

@@supermanlift just disable everything dunno. gsync freesync destroys lag in rogue company. i disabled everything and game is smooth some engines do not exhibit same behaviour such as his tested games... more tests needs to be done on more games...

Yeah I hate when two reliable sources say different things. Who am I to believe ??

Cup of Dylan try both out then make your own decision 🙏🏾 for me g sync on & v sync on in nvidiapanel seems to work better than v sync on in game

@@CupofDylan You can do it both ways. I'd recommend enabling VSync in the NVCP as well as it is reliable on all titles, which is not the case for many in-game VSync implementations. Chris recommends the in-game VSync because it's better than NVCP one in SOME titles.

Same

I'd also recommend using the NVCP V-Sync, I simply cannot trust the in-game implementations for some titles. There are some that do it alright, but why bother?

He explained once that sometimes a game implemented bonus setting for its vsync that could boost performance or quality.

I remember him saying that in-game V-sync could trigger some engine optimizations.

@@Kazanu06 where can I find measurements or proof or comments from engine devs for this :D

I get ghosting

If you are using G-Sync and capping frame rate below monitors refresh rate then v-sync won't add any more latency.

1) if you don't want screen tearing. 2) if you want screen tearing.

@@OfficialKoven and for the less input delay ?

@@lejedidelingo That was my hint. There is no difference in latency.

@@OfficialKoven thank you for your answer sir. So It doesn’t matter if I am in the gsync range I will not have any input lag. By the way, is it normal that if I have the reflex low latency configure to On+Boost that it lower the fps in valorant ?

No. Reflex works like a frame limiter, so enabling it will lock your FPS below your monitor's maximum refresh rate. Hence I don't see the use of using a frame limiter if you have reflex turned on.

ok I found the answer to my question in fact the reflex boost mode does exactly the same thing as in the control panel, 3D settings and switches the power management mode to maximum performance. (on the Nvidia website) Prefer Maximum Performance The NVIDIA graphics driver has long shipped with an option called “Power Management Mode”. This option allows gamers to choose how the GPU operates in CPU-bound scenarios. When the GPU is saturated with work, it will always run at maximum performance. However, when the GPU is not saturated with work there is an opportunity to save power by reducing GPU clocks while maintaining FPS. Similar to the Low Latency Boost feature in the Reflex SDK, the Prefer Maximum Performance mode overrides the power savings features in the GPU and allows the GPU to always run at higher clocks. These higher clocks can reduce latency in CPU-bound instances at a tradeoff of higher power consumption. This mode is designed for gamers who want to squeeze every last microsecond of latency out of the pipeline regardless of power. With GeForce RTX 30 Series GPUs, we are able to set this clock value higher than before, allowing the GPU to target the absolute lowest render latency possible when CPU-bound. Users with older GPUs can still turn on Prefer Maximum Performance and hold clocks to base frequencies.

It doesn't matter much, but i'll put it off on my setting.

For warzone I use “Essentials” with reflex. And set game to mostly low graphics settings.

for warzone use the competitive figuration. IM just wondering if it should be enabled or enabled+boost with its nvidia reflex

NVidia reflex counters this, I think he said that... so you would be correct prior to the release of reflex.

What's the difference between a G-sync monitor and a G-sync compatible monitor?

@@iPlayOnSpica g sync monitors have a custom Nvidia processor inside them that is supposed to result in a smoother experience than freesync

Never enable vsync through the game, it will give more input delay

@@m2u526 specifically modern warfare or any because Battle(non)sense suggested the exact opposite... With a Gsync monitor I mean.

@@m2u526 Yeah, but few milliseconds at most. Not noticable and prevents screen tearing.

For modern warfare, turn on VSync in the NVCP instead of in-game.

I have also tested it and on GTX 1080 i can literally feel the decreased input latency without any measurement. It may actually work better on Cod MW because they probably have some shitty stuff in render code that were adding extra input latency that reflex may be fixing. And antialiasing on that game is TERRRIBLE

@@Navhkrin I also have a gtx 1080, it does feel pretty good in MW with RLL but i was already capping my framerate with RTSS so the frametimes arent as smooth and consistent as before but it may be more responsive (although i cant really tell the difference). However i did notice my gpu gets to 99% with RLL+boost on in-game so I wasn't sure if it was still working. and yeah i just play with no AA although there is aliasing and artifacts from the shadows. and turn off SSR if you arent using the last AA option or there will be a ton of noise in the reflections
