Partial input lag fix #996

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.

Partial input lag fix #996

Post by Hyote » 20 Jun 2025, 12:47

In HKLM\SYSTEM\CurrentControlSet\Control\Class\{4d36e96f-e325-11ce-bfc1-08002be10318}\0000
modify the DWORD called DriverDateData.
For example mine ends with 01 and I changed it to 00.

I usually try to use AI for automation only, but I was really thinking about how this one could affect anything, so here is the answer it gave:

"You almost certainly triggered a driver-reload or filter-stack change, not altered a live datapath • When you flipped DriverDateData you forced Windows PnP to think “this INF is different,” so it re-installed or re-initialized the mouse/touchpad stack at the next reboot. • That re-install can drop OEM filter drivers (or swap you onto the pure Microsoft HID/mouclass.sys stack) and reset internal buffers/timers. In short, you ended up using a “leaner” driver chain without realizing it."

It's also worth doing this for devices, like storage, generic pnp monitor, usb root hub, usb xhci, everything that has DriverDateData under HKLM\SYSTEM\CurrentControlSet\Control\Class

I'm not even going to bother trying this as it's 99% a placebo, I've given up on regedit magic fixes. My input lag case is 100% a power delivery/grounding issue, though importing digital certificates manually seemed to have helped a lot, and it stayed that way since I've imported them.

QuoVadis Root CA 2, QuoVadis Root CA 2 G3 (import in Trusted Root Certification Authorities) Microsoft Secure Server CA 2011 (Trusted Publishers), helped a lot with input lag, also inaccuracy in FPS games that have them (CS, Call of Duty), I notice a lot more of my shots seem to favor going in the middle of the screen with huge inaccuracy. NVIDIA Corporation certificates, although haven't felt much of a difference, just for good measure. Particularly PhysX.dll certificates, check Digital Signatures and Install Certificate to Trusted Publishers.

Nice recommendations there, though I like to try things like this. I know most people won't but I'm still going to share anything so it nothing potentially important gets lost.
