I did a lot of tinkering on my PC trying to resolve this but I found a solution that I don't think has been tested before. The reason I think this is the solution is because when I run Mouse Tester software in Windows Safe Mode, the mouse polling is perfect. It seems to be something related to the GPU driver which no amount of DDU'ing and clean installs could fix.

Disable all your NVIDIA services
- NVIDIA Display Container
- NVIDIA FrameView SDK Service
- NVIDIA LocalSystem Container
I also disabled Geforce In-Game Overlay

This also means that you need to pre-configure all your NVIDIA settings because disabling these services prevents NVIDIA Control Panel from working.

I did a ton of optimizations mainly following Calypto's Latency Guide, getting my average interrupt to DPC latency down to 4us. While gaming, I'll sometimes see DPC routine (nvlddmkm or dxgkrnl) spike to about 500-700us, but these actually make up such a tiny proportion of all the DPC routines. Even so, the mouse still felt weird but after disabling the NVIDIA services my mouse was unbelievably snappy and stable. I feel like I can actually game now. My current configuration is
- RTSS: 155fps with Passive Waiting Disabled
- Double Buffered V-Sync in Game
- Reflex Enabled + Boost
When I ran this configuration before my mouse still felt really slow but now it's super snappy. I also am now experiencing a massive improvement in network performance which I still can't figure why. Before it felt like I had 0 time whatsoever to aim and react but the last few games in ranked I've been taking way less damage and not getting that sensation of being 0.5s behind the server even though my ping is low. I really implore everyone to try this.

So I recently got into Apex Legends and I've come across this issue where my mouse inputs are very jittery/choppy while in a busy area or looking at a large of the map. I'm suspecting its related to high cpu usage and although naturally this only happens in real BR matches I've managed to recreate it in testing range by using prime95 on 4 cores out of 16(9900k)

Description of the issue:
Instability of mouse input processing or frametime spikes NOT VISIBLE ON FRAMETIME GRAPHS caused by mouse interrupts. This leads to a choppiness when panning and tracking enemies.

Here is some 120FPS footage of me comparing mouse inputs to controller inputs.
download the video to view it in 120fps.
-Controller is perfectly smooth while using the mouse results in jitter.
-look at the buttons to see which input I am using.

Here's some footage on a random part of the map. There is not even a lot of activity going on here but the stuttering is still present.
The stutter is much worse when there are multiple teams fighting

I managed to recreate this issue in the test range by simulating high cpu usage with prime95
https://drive.google.com/file/d/1P3RbJg ... sp=sharing


Pretty obvious that the mouse input is laggy compared to controller because the game only processes the position of the joystick at 125hz. Strafing with the keyboard is pretty smooth too as it should be. Only when I move the mouse it becomes laggy

Heres some footage on youtube since the jitters are visible EVEN on 60fps. The 120fps videos show it better though.
Focus on the crosshair, the stutters make the pipe and weapons "vibrate" while doing this type of maneuver.
LOOK AT THE BUTTON HINTS TO SEE WHICH INPUT I AM USING





Things I've tried (main rig) 9900k, gtx 1080
stock windows 20h2
stock windows 21h2
stock windows 7 sp1
125hz, 500hz, 1000hz polling
different usb ports (usb 2, usb 3, front panel)
all devices unplugged except mouse
different mouse, different keyboard, different mousepad
180fps cap, 160fps cap, 140fps cap, 120hz cap. It seems like is reduced the I go but it is definitely still there.
r5apex low priority, high priority
mouse interrupt cpu affinity
different nvidia drivers
cpu underclock
cpu overclock
cpu stock (stock bios)
hyperthreading on, off
different monitor
entirely different rig (9600k, 1650 super)

At this point I just think its the game but how come no one else has noticed it?
I really would appreciate it if someone could try this out on their setup.
If you want to try it out just go to a busy area in the map (might have to try multiple times as it seems very random on which areas of the maps it happens) and do the same movement I am doing in the video footage.

You can also go to testing range and run large fft's on 4+ cores
confirmed that the stutter only happens on 4+ atleast on 9900k and 9600k



Since I've tried pretty much everything I suspect it's just due to a bug in the game engine similarly to how the frame pacing in this game breaks when its running at 200+ FPS, but then again how isn't this on the front page of r/apexlegends?
I've wasted lots of hours trying to fix this and would appreciate if any apex players on this forum could try this out so I know if its just the engine being bad or something wrong with my setup

Have you fixed the problem yet? What is the output for this application: "https://iowin.net/en/wintimertester/"?

Mine is, does this mean something is off? Apex is awful for me in regards to desync.

Friends, I have found the true fix.

Windows Defender.

I was in the middle of a BR match and was getting some choppiness even though my frames were high. I went into process lasso and messed around with disabling different processes. When I disabled MsMpEng.exe, my game immediately felt f*cking magical. I actually could not believe it. I have done literally every possible repair on the internet, literally all of them. Completely replaced my PC, new ISP, clean installs, almost all of Calypto's, Freethy's, and Panjno's optimizations, ISLC, Interrupt Affinity, RTSS, DDU, even Revios...you name it.

You need to go into safe mode, change the ownership of the msmpeng.exe in windows explorer, and then rename the file so it can't run at boot. The problem with just disabling in process lasso or task manager is that the different defender services will restart the process. After I did this, I have no more input stuttering in BR, my mouse sens is 100% consistent, and I'm also getting less desync/input lag/ferrari peaks. I don't know why this fixes the problem, but I'm starting to believe that certain hardware configurations, or certain windows installations like ours seem to have a problem with Easy Anti Cheat. And no, adding these things to exceptions doesn't work, you need to fully disable the process. This might be why all these fixes only have temporary resolution, because no matter how you change your hardware, reinstall windows, change cpu power settings etc, Windows Defender is always there. Come to think of it, I have always only had mouse lag problems in games where Easy Anti Cheat is involved: Battlebit, The Finals, Apex, Halo Infinite...

Please try this.
