Hi there.

I want to point out in the beginning that not everyone might experience the same issues but I've realized that high-end PC shouldn't be lagging as much as mine did.

I've been trying to figure out this issue for a week now since I've built my PC. My PC would suddenly start being slow and unresponsive for no reason. No matter if I was in a game or browsing or even being on desktop only.

Issue: My PC would start being slow. If I would press on the Windows key, for example, it would take at least 3 seconds to open a start menu and the animations all over Windows during this state were terribly laggy.

For the sake of this post here are my specs:

GPU: EVGA RTX 3070 XC3
CPU: Ryzen 5 5600X
Motherboard: X570 Aorus Pro Wi-Fi
PSU: EVGA SuperNova G2 850W 80+ Gold.
SSD: Samsung 960 EVO M.2 250GB

Razer products I use: Razer Kraken Ultimate, Razer Blackwidow, Razer Deathadder V2, Razer Kiyo

Now, we all know that this is possibly one of the high-end gaming combos you can build in 2021 specs-wise so it being laggy and slow makes no sense.

When this issue was starting a simple restart or sign out and sign in would fix it but nothing else. I thought it was my motherboard and disabled the XMP profile but no luck.

How I Fixed It:

I used a well-known tool for some of you called "Process Lasso"

You can get this software for free and it's easy to find in Google hence I won't be leaving a link address of it. During the installation make sure that you enable it to start for all users after login.

Steps:

1. Open Process Lasso

2. Locate Razer processes:

Razer Synapse Service Process

RazerCentralService.exe

RzSDKService.exe

RzSDKServer.exe

Razer Central.exe

Razer Synapse 3.exe

GameManagerService.exe

Razer Synapse Service.exe

THXHelper22AD.exe

THXHelper0527.exe

As you can see there are many of them but you might not have them all which is okay according to your peripherals.

You might also have some motherboard RGB stuff like RGB Fusion of Gigabyte or Aura for ASUS and etc.

3) Right-click on each process: CPU Priority > Always > Below normal.

4) Right-click on each process: CPU Affinity > Always > Select CPU Affinity > Clear > Select CPU 0 only > Press OK.
5) Repeat the steps 3 and 4 for all the above-mentioned processes.

Restart your PC (optional)

Disclaimer: I have not tried setting priority to Idle since it might affect the actual process to work properly but you can give it a try.

Your PC being laggy and unresponsive should be gone.

I still have no idea why the issue is there in the first place but this free fix should do the job for you.

Cheers.
