This Is How I Fixed My Input Lag

[Foul Play]

For some reason, ether there's a bug with Windows' HAL or I found a way to brute-force Windows' to use the CPU Cache over the System RAM etc and but setting the Registry Key values in the attachment and following this Power-shell script fixed my input-lag: viewtopic.php?f=10&t=13044.

The Registry Keys are related to how Windows detects the amount of CPU Cache ether Reg Key Value or HAL.

I'm using a 5800X3D which has 100-ish Megabytes of Cache so this might not benefit lower CPU Cache amount and I have no other systems to test this on, I can't test it out.

That's all the tweaks I did on a fresh Windows 10 and 11 Home.
I've been playing GTA IV and CS2 and mouse is now 1-1 for me. I'm testing more games as I post this.

Maybe this will help people so GLHF.

The thread that you linked to doesn’t mention the cache registry values - google isn’t telling me much either - can you tell us more about them?

I thought people could see the image attached to the post, my bad.

The Registry names are:

Code: Select all

FirstLevelDataCache

Code: Select all

SecondLevelDataCache

Code: Select all

ThirdLevelDataCache

in:

Code: Select all

Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management

All keys are set to in Hex:

Code: Select all

ffffffff

It shows up but it's not readable due to small text (image zooms down to small 1080p gaming monitor), unless I do the [URL=link][IMG]link[/IMG][/URL] trick.

Here is the clickable-zoomable version:



I may have to modify the forum software to let people zoom attached images, especially on small screens and mobiles.

I have a 5800X3D and play competitive FPS, will test this tonight.

Unrelated: I just upgraded my stream PC's capture card from an HD60 Pro (capturing at 1080p 60fps via cloned desktop) to a 4K60 Pro (capturing at 1080p 240fps via cloned desktop). I upgraded because I wanted to stream at 120fps, I had no idea that my stream PC's capture card could effect input latency on my gaming PC... but after swapping out the old card I'm embarrassed to say that I've been playing with input lag for years.

To other dual PC streamers: Beware.

Do you have a way to measure CPU cache utilization? I have no doubt this made a difference in your system's performance, I'd just be interested to know why you conclude that your PC now prioritizes L3 cache using these settings.

I have SecondLevelDataCache and LargeSystemCache only. What does it mean in that case?

What I meant was that I'd like to know how you found out that you should set these registry values in-particular, because they aren't mentioned in the forum thread you linked to.

I'm testing it in like 1 hour, give feedback, same CPU.

Same for me, what should we change? Should we manually add FirstLevelDataCache and ThirdLevelDataCache values?
