Blur Busters Forums

Hello Everyone,

This is my first BlurBusters post but I have been lurking throughout the forums for the past few years looking for a solution to solve my input lag and frame time issues that had not disappeared until a few days ago when I implemented this method I found after trial and error. Before I get into it, I have built a few PC’s over the past few years and have done everything possible in Windows and Bios to mitigate my floaty mouse and seemingly delayed and choppy frame times that feel like my mouse movements are behind my hand movements. Though it was frustrating, I am sure some of you can relate as to how much knowledge you gain from troubleshooting issues, so it wasn’t entirely time wasted.

I am still testing with other latency optimizations so you can tweak accordingly to your preferences, but this is my method so far.

Method:

-Make sure you have Nvidia HD Audio Drivers installed.

-Disable all Realtek Audio in device manager, then disable in BIOS. Though I haven’t uninstalled mine yet, you could DDU Uninstall all Realtek Audio in safe mode and try. Just know you have to disable audio drivers in BIOS so windows does not reinstall them.

-Disable every audio driver in Device Manager except Nvidia HD Audio.

-Plug an HDMI cord from your GPU to your HDMI port in your monitor.

-Plug headphones into monitor headphone jack.

-Go into sound settings and disable all other audio inputs/outputs except your monitor audio coming through your headset. Set audio quality to 16-bit 48000hz (DVD Quality). Check disable all audio enhancements off and on recording set noise suppression to “Do Nothing”.

-Go back to Device Manager and uninstall all monitor drivers. You should see 2 monitors connected there with generic drivers, 1 that is connected to your DP and the other is connected to your HDMI. Disable both of these.

Restart your computer, making sure the only audio present is the audio coming from Nvidia HD Audio.

Bonus Settings (My Tweaks So Far)
-All high typical high performance GPU settings in NVCP
-HPET Disabled
-High Performance Power Plan
-Memory Integrity OFF
-1728x1080p Custom Resolution
-Disabled Bluetooth Drivers
-Disabled Wifi Drivers
-XMP Enabled

I did this all on a fresh install of Windows 11 Pro.

So far the results of this for me on Apex Legends with input lag and frame timings is unreal. It feels like I have RTSS frame times with only an in game cap of 240 through steam commands. I have yet to test it on any other games but will soon. I have tested just using DP Nvidia HD Audio without the second HDMI connection and it didn’t give me the same results at all.

I realize not everyone has a headphone jack for their monitor and it’s not typically ideal to go this route but for those out there struggling, maybe this can help. I don’t know why this works for me, but I am suspecting bad grounding at my apartment complex that is causing electrical interference with not only my computer but my TV as well. That’s an entirely different subject though…

Let me know if this works for anyone else, I want to confirm and verify it’s helped someone else’s system other than mine. Thanks GL!

SPECS (Brand New Build):
-Ryzen 7800x3D
-RTX 4070ti OC
-6000 G.Skill RAM
-850w PSU
-B650 Aorus Elite AX Rev 1.2
-1 TB Western Digital SN850x SSD
-Zowie 2546K 240hz Monitor with Dyac+ ON and AMA High
-Logitech GPRO Superlight 2

This isn't new... but I do acknowledge it can help.

It depends on the computer, and not a guaranteed solution because there's lots of causes of lag that is hard to troubleshoot -- but it can sometimes be the cause, e.g. switching between NVIDIA and Realtek audio drivers. There's been times where using the NVIDIA GPU's own audio drivers can often improve performance.

Audio drivers have indeed added lag before; there's some existing old threads on it. But those threads get buried quite quick!

I do like the reminder that mudane stuff such as audio drivers can be a big lag/stutter problems on some systems that actually are using the less optimal audio drivers.

I can imagine how fast certain posts get buried in the never ending pit of input lag fixes and troubleshooting! Seems like so many people deal with it for all types of reasons. I apologize if this isn’t a new method as stated in the title! Hope this helps someone like it’s helped me.

...

Is your game at a high competitive level? Are the improvements to your gameplay noticeable?

reason of all issues with audio drivers (realtek/nvidia), is non-msi mode by default.
after you install driver, you will be in msi mode.
just use msi mode with default drivers give you best result.

i mean bro surely placebo let us know if your issues return i have a 3k pc and it sometimes feels like dog shit i know my pc is set up correctly but maybe my internet line is just slammed by my neighbors who all have copper too , i dont think what u did is even a thing ?, in my head im like no apex pro does any of this and some r on 600$ potato setups with 100fps and still go lan and win a bag i dont think our pc audio drivers r the reasons for our bad feeling aim or input delay gd post just my 2pence

there is a difference between soft lag and electric lag

Stumbled upon this after trying to figure out why my audio device didn't have the "Enhancements" tab. So happy I did.
I didn't go the distance of what op posted, simply installed the HD audio driver in place of Realtek and the difference was instant.

At first I thought I'd made a mistake because my sensitivity in game felt faster, then I realized I didn't need the bit of mouse accel I had been using. After disabling accel in-game, it only took maybe an hour to get used to the changes. I began to notice my hit registry feeling better and tracking being more accurate. Flicks started connecting where they'd usually miss and I started getting more cocky and trying for more outlandish shots, many hitting where before they'd miss 9/10 times.

I simply followed the steps in this video: https://www.youtube.com/watch?v=dyyp7qv-HBo
Then tweaked EQ loudness once I could access enhancements: https://www.youtube.com/watch?v=UpsJLV2hV64

can you try disable onboard audio in bios and retest it?
