I've Discovered SOME very important Key FACTORS of the mouse input latency for Some. I think it's GPU RELATED
Posted: 10 Jan 2022, 01:03
With careful introspection, I've noticed a few things in regards to my input latency. I've been experiencing Inconsistent, Floaty mouse, feels like the cursor is fighting against my movements etc. Mouse feel changes between Applications and webpages etc. I thought it was just a general inconsistency due to the nature of it being a possible "power issue". Now I'm convinced it isn't power related at all (for some, or maybe even most) and is GPU i.e = Monitor, UI, Hardware acceleration, Graphics Card, DX driver etc related.
I Think I've found a MAJOR discovery for some of us
I saw a post on Microsoft about disabling Hardware Acceleration on browsers to decrease mouse lag, sure enough it made my mouse feel snappier and pretty much normal on Chrome. Yet I still noticed the weird inconsistencies, with careful inspection, I noticed my mouse slows down/lags over almost ANY clickable link, icon, picture etc. Like it introduced mini Vsync/Hardware accel over these things in that instance, resulting in a floaty, inconsistent feeling like my mouse was fighting against me. I was able to recreate the mouse lag I feel when browsing indiscriminately, by moving my cursor around with Hardware acceleration on/moving over links etc.
Most people would never notice this or even think of it as an issue, and would put it off to being caused by something else. I disable hardware acceleration on chrome for example, and move my mouse back and forth in an area with no clickable UI options, my mouse feels PERFECT.
I googled this aswell, and several forum posts of people having a similiar issue (lag when mouse moves over Clickable UI interfaces or the entire application, if Hardware Accel Is enabled) surfaced. A few of these seemed to be caused by some bug with multiple monitors ? Which I don't have.
I tested one of the games I like to play, but it's almost impossible due to the inconsistent floaty mouse lag, league of legends, and the same thing pretty much held true. My mouse lagged over ANY clickable/interactive U.I interface parts of the hud.
Also, when using GeForce Experience overlay, with a game In Fullscreen (Alt+z) the mouse movement feels almost exactly how it feels when I get that floaty, inconsistent, laggy feeling. Except it's over the entirety of the screen. Opening it on the Desktop doesn't lend the Same results. First person/Reticle games don't suffer as much (I'm assuming because of no "clickable UI elements?") but sometimes if I have an app open with hardware accel i will feel that same lag
In conclusion, I think for alot of us it might be a GPU (possibly monitor aswell?) Issue, something related to UI interface, Graphics Card, Hardware Acceleration etc. Anything GPU related. Not related to "dirty power".
Here are links to a few posts with people describing the exact same thing. Sound familiar?

There's even more, but I think that's enough for now. I'm 98% convinced it is a GPU issue in some way shape or form. Yet, I don't know how we'd go about solving the issue. Is it an Nvidia driver issue? Microsoft UI/Interaction being buggy? Certain cards only? What are your thoughts
