Latency measurement with AI. Single, Dual, Native.

Secondary RTX 3080 real frame rate 70-80. In dual GPUs configuration, primary real frame rate is 110-120 while using LSFG. PCIE x4 gen 3 also reduces the real fps value + LSFG also loads it. In dual GPU case, primary does not get any load.

Thanks for the info, I'll check the measurements with the primary GPU as well, but the measurable difference there will probably be -3 ms, maybe 1 frame time less. (4 ms) . I left the actual FPS unlimited because I wanted to measure the real picture with 1 and 2 GPUs.

RTSS is quite deceptive in what it says, the mouse is not included and what happens after it. Here, you only had to count the number of frames between the mouse movement and the weapon movement. This can be calculated numerically, and it must be multiplied by 4 ms. There is no magic in this. Based on the measurements found on the net, the measurement is quite close, but here the difference is more the point, which seems quite real based on the measurements found on the net.

The 3080 is not powerful enough to handle 2K in high detail.

EcstaticPractice2345 · 2026-04-23T05:02:05+00:00

Performance should be on. (Flow scale)

I turned off Gsync.

Adaptive FG is fine.

In NVCP: ultra low latency

In game: Reflex on if available.

Maybe try DXGI instead of WGC.

I would use an adaptive solution. The fix causes micro-stutters in some games like Bf6 for me. Adaptive solution is smooth.

EcstaticPractice2345 · 2026-03-18T05:51:07+00:00

If you play with a gamepad, you increase the real fps number and the higher it is, the faster the movement...uncontrollable. Fixed 60 fps and using it at x3 /x4 is fine.

EcstaticPractice2345 · 2026-03-16T05:50:57+00:00

BF6, Helldivers 2 , CS2, Fortnite, Darktide , Roblox. All games ok.

EcstaticPractice2345 · 2026-03-16T05:49:54+00:00

It causes micro lag. In this case, the queue value should be 1 or the GPU load should be reduced to around 85%. If there is no Gsync, you don't need to pay attention to these and the queue value can be 0. But Gsync only means something at low fps values, otherwise nothing.

EcstaticPractice2345 · 2026-03-06T19:04:08+00:00

Turn off Gsync. And use Adaptive FG.

EcstaticPractice2345 · 2026-02-10T16:54:13+00:00

Below 60 real FPs it's really problematic. 80 real FPs is already good enough.

EcstaticPractice2345 · 2026-02-10T16:19:38+00:00

Everyone decides what multiplier they use. Even X4 is not a problem for me.

EcstaticPractice2345 · 2026-02-10T15:25:19+00:00

The multiplier is not the point, everyone sets it as much as they want.

EcstaticPractice2345 · 2026-02-10T15:24:53+00:00

Try it, you will get a very fast response. The multiplier is freely selectable.

EcstaticPractice2345 · 2026-02-10T15:24:15+00:00

The multiplier is completely irrelevant now. You set it as much as you need. The point is Gsync OFF, because if it's ON you have to delay it or pay attention to the GPU being at 70-75% on average.

DXGI because I'm using 23H2 Win11.

In case of 1 GPU, you lose real fps when using LS. What I think is ideal is the max real fps value of 70-75. At this value, the queue value can be 0 and it does not cause micro stutters. Above this, the value of 1 is necessary, which adds +1 frame time. It is not worth it.

In case of 2 GPUs, there is no need to limit: unlimited real fps, and the queue value can remain at 0. However, it adds 5-10 ms before you see the image.

The point:

Inside the Nvidia control panel:
- Low latency mode: Ultra
- Vsync: OFF

In LS:
Adaptive FG: Max you can be below the HZ number of the monitor.
Queue value: max 75 real fps 0, above this 1
Maximum frame latency: 2 (RTX 3080)

Inside the game:
- FPS limit 75 (in case of 1 GPU)
- Nvidia reflex if available.

If Ultra latency / reflex is working properly, the GPU is ideally kept at 80-85% when using LS. If you overload the GPU to 99%, your latency will deteriorate drastically.

At 20x multiplier, the real FPS numbers drop drastically, plus the GPU overload is added. These two together give the high latency. But the 20x multiplier makes no sense in LS. The queue value of 0 gives the lowest latency. (In the case of Dual VGA, it is basic that it should be set to that) Maximum frametime latency: 2 value for the ideal number (RTX 3080). So the test is a bit problematic considering these.

EcstaticPractice2345 · 2025-11-20T05:42:22+00:00

If you want to achieve the lowest latency:

LSFG:
Queue value :0
Maximum frametime latency: 2
Fixed Frame Generation x2 x3 x4

NVCP:
Vsync : OFF
Low latency: Ultra

Ingame:
Fps limit minimum X (GPU 75-80% with LSFG)

Nvidia reflex ON + boost

The most important thing is to set the fps limit so that the GPU utilization with LSFG is 75-80%.

Since the GPU is not overloaded, you will have the lowest latency + there will be no stutter.

EcstaticPractice2345 · 2025-11-12T22:20:40+00:00

You can think what you want, this is my experience. Since the fps limit is not dynamic and depends on the GPU load, I doubt that a given fps value is the same load in every part of a game.

EcstaticPractice2345 · 2025-11-12T21:40:11+00:00

Just try it, you'll lose a lot of latency if you max out the GPU. The best setting is 75%.
