Don't know if this works for anyone else, it's been working for me for the past days.

I changed the CPU affinity for FFXIV. It might be worth testing.

For me, I set Priority to High and Affinity to only six cores.

For people who don't know how you do this.

1: Start the game normally.
2: Open task manager, go to details and look for FFXIV_DX11.
3: Right-click and change the priority to High and set affinity to 4-6 cores, or rather 4-6 threads. For me, I chose CPU 10 through 15.

The problem is that you have to do this every time you start the game, I made a script that does this for me but you can test it manually and see if it works for you.

I can help you make a script if this works for you, my is a powershell script that looks like this.

Get-Process ffxiv_dx11 | ForEach-Object {
$_.ProcessorAffinity=64512
$_.PriorityClass='High'
}

Save it as a .ps1 file and you can right click it and run with powershell.

What you have to figure out is the correct number for the Affinity, you can do this by following the first steps of the guide, open powershell and run...

"get-process ffxiv_dx11 | select ProcessorAffinity"

And you will get the correct number for your script file.

Also, if you have problems running the script you might have to start PowerShell as admin and change the execution policy by running the command.

"Set-ExecutionPolicy Unrestricted"

Hope it works for other people as well.

Still, THIS IS A WORKAROUND, SQUARE! This is not a solution!
