low latency mode

Everything about latency. This section is mainly user/consumer discussion. (Peer-reviewed scientific discussion should go in Laboratory section). Tips, mouse lag, display lag, game engine lag, network lag, whole input lag chain, VSYNC OFF vs VSYNC ON, and more! Input Lag Articles on Blur Busters.

i can feel a significant difference between ultra and off
positive difference?
Yes. With off I can feel input lag. Ultra feels snappier

I usually play Valo, and for me, setting low reflex latency mode thing in-game to off, and actually set nvidia to ultra low latency. just feels more responsive overall.

LLM off = no limits (the game sets the queue size itself)
LLM on = 1 Frame
LLM ultra = 0 Frame (is like a real time pre rendered frame so its like) but if cpu is not fast enough to render frame "on time" to the gpu, then it result in stutter

setting this setting on or ultra, makes my pc crash/blue screen in csgo. Meaning i'm forced to play with it off.
My GPU usage with my 1080ti is only around 50 %(Native +very high settings), so it should'nt make a big difference anyways. Still annoying.

1. I advise you to use OFF (where you are not GPU bound).
2. Always cap your fps.
On is always better than off, unless you suffer very low fps! On equals 1 pre-rendered frame, while off like 2-3 (I think it was somewhat dynamic) which adds additional latency!

On is best in 99% cases, unless your GPU is constantly maxed, then Ultra is best!
Sorry to destroy your bubble, but that's just wrong. Low Latency mode only helps in GPU bound scenarios. Thats when your GPU usage gets over 90%. Then Low latency On or Ultra will help. If your GPU is under 90%, both options won't do a Single thing. In fact, Low latency Mode can increase input lag while applying a FPS cap, if you are under 90% GPU Usage! Capping FPS either trough game settings or RTSS will cut off more ms then Low latency mode/Nvidia Reflex. Cap FPS until your GPU never goes above 80% and you have a better self made Low Latency mode ;)

Its just important to cap the frame rate bellow 90-99% gpu usage. That's pretty much it.

For additional, small latency reduction: the Lower the gpu usage, the lower latency.
