Anti-Lag+ vs Nvidia Reflex! | Why AMD Anti-lag+ is Great, but it Doesn't Matter.

==JOIN THE DISCORD!==

AMD released Anti-lag+ because they need lower latency on their graphics cards in-general, but also to mend the issues caused by FSR 3- frame generation. This is competing directly with Nvidia's Reflex technology which has existed for a while and held them at the king of the market in terms of GPU and overall system latency. So this video is sort-of a Anti-lag+ vs Reflex, but there is a lot more to it.

There are some specific issues with Anti-lag+, especially since it is exclusive to Radeon rx 7000 series GPUs. I was able to test it because I've got an rx 7800 xt, although most people aren't in this position. What does this mean when FSR 3 Frame Generation is backwards-compatible with older GPUs, but Anti-lag+ is not? Why Anti-lag+ is great, but it doesn't matter.

These technologies try to minimize the caching between CPU and GPU. When you are CPU limited, there is by nature no caching, as your GPU is always rendering the most recently calculated frame (so anti lag or reflex don't do nothing as this latency is already as optimal as it can be).

However, when GPU bound, you get in a situation where the CPU may complete the calculations for a frame, but because the GPU is still drawing the previous one, this recently calculated frame is put on hold (the caching), thus introducing extra latency equivalent to the time the already calculated frame was on hold.

This does mean that intelligently discarding calculated frames before they reach the GPU, or even dinamicaly slowing down the CPU, results in relevant amounts of latency improvements (among other techniques I'm ignorant of)

With the nvidia overlay if you toggle the advanced performance settings you can see total system latency in most of the games on top of the render latency

This has been a big topic of my own recent speculation about my 7900 xtx and other cards @Vex thanks for the solid upload brother!

[carlosmarques]

Like you said at the begging frame generation hold up frames to create new (between) frames. So even if you're CPU limited with DLSS 3 and FSR3 you will want the Reflex / Anti-Lag+ to mitigate this 'forced' lag.

[defeyterjelle]

Vex, FS3 has it's own latency reduction, it has nothing to do with Anti lag (+). That means you can use Anti lag (+) ON TOP with FS3

[TheCompyshop]

AMD said that they aren't going to limit the new tech to the 7000 series forever, they just designed it with 7000 series in mind, but they are working on testing and making it work on older gen cards

7:30 well because Antilag's competitor on Nvidia side is not Reflex but Ultra Low Latency which you can find in Nvidia Control Panel under 3d settings. Reflex is not on driver level but implemented into the game. Ofcourse it's going to have a turn on-off switch in game. Antilag+ just like Reflex is implemented in game but for some reason just like they did it with Radeon Boost, you need to use Adrenalin to turn it off. They probably just give all 12 games a go immediately with the new drivers, otherwise we would need to wait for those games to update and add the setting in their menu. Anyways just like you said both have advantages and disadvantages.

[poodledoodle]

This is wrong on so many level, FSR3 includes an integrated latency reduction feature that’s the equivalent of Reflex, AL and AL+ are just additional settings on top to further reduce latency

[ChinchillaBONK]

Btw, humans can't perceive lower than 13ms latency.

So it's basicly back in 2013 era. When Amd made a software to do the same thing as Physx because nvidia locked the software to nvidia cards.

But then the ps4 debacle which had a amd gpu with native physx support..

So what happens on pc is at the time..if you put a Nvidia physx capable card in 2nd slot and a high end Radeon card in first slot.

Nvidia physx software would detect the Amd radeon card and disable hardware accelerated physx, forcing it cpu process.

On the surface of it cpu can be quite capable of doing this...however physx is not made for cpu tasks its made for Gpu task..so you get incredibly poor performance on cpu.

Eventually Nvidia got sued and stopped being ass hats..and have unlocked Dedicat3d physx handling on specific cards...like if you have a secondary nvidia card, it can be used for just running physx calculations. And now even so physx can be run on gpu metrics even with a Amd card..

This is priopitary software Bs compagnies try to do to control the market, as they know that people will want those gimmick since raw hardware performance is relativly similar on both side.

Dlss / fsr and reflex / anti lag+.
Is more of the stupid game over and over again.
Except here Amd and Nvidia are both freinds and both try very hard to change pc gaming to the point of everything being behind software that will at one point in the futre...make it impossible to play without it..and this open to subscribtion scams.

So they decide when a gpu familly is done for and that you can't use them for anything.

This software rebellion is very sad, because instead of just Nvidia being ass hats..Amd actualy do the same now..

I hope intel is not jumping in this bandwagon in terms of just being another fake competion.

I've just been using an fps cap so gpu load never goes above 90% and that way you don't get the additional input latency in the first place that reflex and anti lag are supposed to prevent, games feel the most consistent that way. Having no fps cap and reflex or anti lag may result in slightly lower latency in some situations because it allows for higher frame rates but the fluctuating framerate and therefore fluctuating input latency is not worth it imo as long as you get more fps than your screen can display.

[toinouH]

Nvidia reflex also work on 800 series but as being a pre-maxwell mobile only thing they don't advertise it but it works like the GTX 850M :)

[chipbong]

95% cpu utilization = 16 threads on 5800x3d but tech vloggers say all you need is 6 cores for gaming.

[Fezzy]

the +boost part of reflex just locks the clockspeeds of your GPU to its max clocks. Its the same as enabling "prefer maximum performance" in the nvidia control panel.

you can also enable reflex in the nvidia control panel for any game. the "low latency mode" setting is reflex with the "Ultra" setting being the reflex+boost.

[deyandimitrov]

Cool video! I would be very interested in a video where you compare normal Anti-Lag vs Anti-Lag+ to check out how big is the difference actually and is it worth upgrading to the 7000 series.

[TheIndulgers]

I really don't like the measuring tools. They don't seem comparable or completely honest. Overall end-to-end system latency reduction is what I want to know, so the LDAT or better yet a high-speed camera is the way to do it imo.

[rain]

These tech are supposed to be the most helpful when you're GPU bound so Reflex will be much more useful in a game like Cyberpunk compared to Overwatch. It essentially allows you to use your entire GPU without extra latency penalties that typically occur during high GPU usage.

Now AMD markets on extra raster performance but all that extra FPS is pointless when you need to cap your FPS below what your card can get to get equal input latency anyways.

[jayguy]

As stated by another commenter.
NVIDIA REFLEX/ANTILAG work ONLY when GPU bound.

Do your research before riding off the back of Daniel Owen’s video who also got this fact wrong. It’s obvious you’re copying when you’re both wrong about the exact same thing just days apart.

Embarrassing

[Triro]

Oh yeah. And Anti Lag works on every single game. Sense its baked into the driver itself.
While anti lag+ needs game support. which is really a shame.

[KyoukiDotExe]

Apparently these tech work best when the GPU is hammered the hardest.
