I finally captured evidence of input lag

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.

I finally captured evidence of input lag

Post by Sandy » 30 Jul 2025, 13:55

I can't create a horizontal video on YouTube. Does anyone know how to do it?

This indeed looks horrible. I made a few videos but deleted them all because there was only a bit of visible delay, but you're the input lag winner for now.

Actually, this video I shot shows that my input lag is low. At other times, the lag is much higher than this. I can only hide in the corner and shoot secretly. This problem has troubled me for many years.

I've tried this many times and the input lag is the same.

This happens to me in pubg after the first 1-2 matches.
How do we fix it?

To prove input lag isn't related to the internet, I tested it disconnected from the internet. I tried everything I could. I believe the lag could be due to electromagnetic interference in the air, affecting the computer's chipset and CPU, and this interference is unfixable with current technology. Another possibility is an operating system issue, but other operating systems can't run FPS games, so I can't conduct a controlled trial. I follow many professional CS2 players, and they also complain about input lag. For example, s1mple... Even in an offline CS2 tournament, if ten players each used ten identical PCs with the same power supply, some still experienced input lag.

Windows being properly configured matters a lot and even though this is just a really short video, this is my overall experience in every game now. Pretty much having all the small fixes applied from this forum and from other places plus using a USB-to-ethernet adapter get me gameplay I could call nearly perfect regardless of any kind of outside influence to my input lag.

It looks like you have no input lag. What adjustments did you make? Can you share more details?

I used all of what is available on my GitHub pages and I'll list everything else.

-Custom Resolution Utility: used Exact Reduced as a base, changed to Manual to reduce Vertical Total.

-After every startup I delete the monitor's EDID in
HKLM\SYSTEM\ControlSet001\Enum\DISPLAY\<>\<>\Device Parameters
then restart the screen with Win+CTRL+Shift+B
Apparently it does this: discard the desktop surface buffer and re-create the allocation from DWM.

-Disable DWM before running games with the script and set its priority to Idle.
