PCIE card significantly reduces floaty aim despite perfect dpc latency

[apachenikov]

Hello ! I have been dealing with floaty aim issues and been OBSESSED with fixing it, it happenned a few weeks during or after upgrading my whole setup:

old config:
ryzen 3700x
ASUS-TUF-B450-PLUS-GAMING
BALLISTIX 16 go ram
cooler master k550 psu
asus dual 4060ti

updated config is:
ryzen 7800x3d
msi mag B650 tomahawk wifi
corsair 32go ram
corsair M850e
asus dual4060 ti

less relevant: I also changed screens from an old TN panel 144hz screen to a 2K 240hz OLED and changed mouses from a razer viper to a pulsar X2H

I was playing cs2 during all of those changes and my frametime was pretty bad, i figured because my cpu was VERY outdated, but the feeling was off, I tried going back to old fps titles that I was used to playing (because I could compare the mouse movement without the frame pacing interfering) and it also felt off, even with perfect frametime.

I tried many things:

-Motherboard swap (x2 — MSI MAG B650 Tomahawk + ASRock B850 Steel Legend)
-PSU swap (x2)
-GPU driver clean install with DDU
-Disabled integrated AMD GPU
-Fresh Windows install (x3+)
-LatencyMon
-MouseTester
-Disabled WiFi driver in BIOS
-XHCI Hands-Off disabled in BIOS
-MSI Afterburner framerate cap
-PCIe USB expansion card for mouse
-Old Ethernet driver update
Disabled Nvidia Reflex
-bcdedit useplatformclock / disabledynamictick
-Disabled MPOs via registry
-HAGS enabled
-Disabled Spread Spectrum
-Disabled Realtek audio drivers
-Multimeter on power outlets (everyhtings seems fine)
-Cut all circuit breakers except PC
-Disabled WiFi update via wushowhide.diagcab
-Tested different power strips (x3)
-Scaling at 120%
-Disabled FSO via registry
-Disabled Secure Boot
-GPU power limit investigation
-BIOS options (C-states, Legacy USB, spread spectrum, etc.)
-tried different screens and mouses

the only things that made a small difference were uninstalling the wifi realtek drivers and XHCI hands off disabled in bios, I thought those elements were pointing to a faulty motherboard, but i replaced it with a newer one with different drivers and nothing changed, then I replaced the PSU thinking the electric signal coming from my psu was polluted (sounds weird, but my psu was almost a decade old and not very good, so I figured why not try to replace it) but nothing changed...

recently I bought a PCIE card, to plug my mouse, I wasnt hoping much, but it was a NOTICABLE difference, much better than before, the improvement was bigger in intensity than all of the things I tried that kinda worked.


I then tried to diagnose an issue in my computer because it didnt make any sense, [if pcie works better...why does changing the mobo do nothing???] but my dpc latency is almost perfect in LatencyMoon, my DPI is stable in MouseTester, my components are behaving normally in all troubleshooting softwares like Prime95, my building seems fine in terms of electricity ( its new and in western europe, and outlets have normal tensions )........

...I just don't know what to do anymore, it used to work fine, I'm only glad that I know I'm not schizo because the PCIE card does significantly improve and recudes floaty aim, but everytime I try to pinpoint the "failing area" of my pc with the knowledge that the pcie card improves things, it doesnt lead to anything.

(sorry for bad english, dont hesitate to ask me to clarify things)

update : disabling "core isolation" in windows defender has also improved my responsivness greatly it seems, I don't know for sure but the difference is so noticable that I doubt its placebo, if it is I will update this topic again

It's not placebo. Core isolation adds a significant amount of input latency because it's a protection mechanism for malicious drivers. With core isolation on, all your devices have to talk to core isolation first to check if it's not malicious, then it sends it off to the kernel to get processed. I have it off, malicious drivers aren't a thing to worry about if you don't download sketchy stuff off the internet.

do you not play faceit?

No, and I stay away from games/things that require any kind of kernel level protection. Ever since i made this decision, my computer has never crashed ever. If your computer crashes, it's because of these kernel level anti-cheats not playing well with your drivers. Also bad drivers can do the same on their own. So many times my computer would crash unexpedectly for no reason and I would lose work over it. But it hasn't happened since.

Yeah the other day had unninstalled faceit anticheat and my boot time lowered from 20s to like 5s. But its the only way to play CS2 with less cheaters. Of course people still cheat with their AC but compared to premier its night and day difference.

So what are you trying to say ? using a PCIe USB fixed your mouse feeling ? also disabling "core isolation" can't do it with faceit.

It's not placebo. Core isolation adds a significant amount of input latency because it's a protection mechanism for malicious drivers. With core isolation on, all your devices have to talk to core isolation first to check if it's not malicious, then it sends it off to the kernel to get processed.

It's possible just reducing the amount of devices connected to your computer would be enough to reduce the impact it has on input latency. So limiting the devices to only mouse and keys may help. From what I think is happening is, core isolation becomes the bottle neck, because it intercepts everything going to the kernel. If there's less to intercept, then maybe less impact on input latency?

But I mostly stay away from it because of the crashing. It's really annoying. I have my setup pretty good when it comes to input latency so, i don't think core isolation will have an impact for me.

Which one did you use specifically? I want to try it out and update if it helps most of us or if it’s just helping for your specific case. Ty for your post! :3

so I dont think I can type links here and I'm french but its the "KALEA-INFORMATIQUE Carte contrôleur PCI Express USB 3.0 2 Ports Type A, Auto alimentée par Le Port PCIe et avec Chipset NEC D720202" basically its a card with renesas drivers, just search for the name of your drivers on your pc and try to get a pcie card with different drivers (so it eliminates the possibility of your drivers being the issue), it sure made a noticable difference but it didn't fix everything, I have a very weird input delay issue and I can't find similar cases to mine here... so I don't know if this will help you for sure, usually it helps people with high dpc latency on LatencyMoon. no problem !
