Windows 10: Valorant Lag after 21H1 Update

So I'm having huge fps drop spikes on VALORANT whenever someone fires a gun and I'm so irritated by that. Before I even update my windows, it doesn't lag at all, I'm getting the usual FPS when I fresh intalled Valorant because I quitted for 2 months after getting an error in the game. And now, I played 1 game on it before I update windows and it doesn't lag, but after I updated it manually, it does this lag on Valorant. My PC becomes smooth but Valorant had fps drop spikes and I can't play it.

Intermittent UI lag - Windows 10 21H1

Problematic files are photos and videos at this point in time. I use VLC for videos, and Windows Photo Viewer for images.
I launch all these directly and manually from File Explorer only - I don't use any third party media organizers.

Interestingly enough, mngerholds suggestion of using Procmon has unveiled that when lag does happen, there is a large influx of UDP and NetBIOS entries via SVCHOST -- but I'm yet to narrow down what the trigger condition is...

When there is no lag, UDP and NetBios entries are not present.

Here is a healthy launch of a file:




Here is a laggy launch.

Hi,

We would like to know more about your lag issue:

• What browser are you using when you experience a lag?
• Does the lag occur in a particular game?

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting.
• On the left pane, click on View All.
• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.

 

Windows Updated(16299.309).KB4088776 Restart is required to complete.

Hi dalchina. Good news, I followed your suggestion and reinstalled the update and now it appears as "installed correctly" *Biggrin Maybe it was not necessary to run the Windows Update Troubleshooter or maybe if necessary. But using it I do not think it could have worsened something. The installation was very fast, unlike the first time it showed step 1 and step 2 completed.

Thanks for the suggestions and for the time to respond Best regards.


And thanks for the tip of that program, I'll have it on my list.
