Pretty cool! Thanks bro.

No problem!

Hello Francis.

How does this fix work? Is there working exe that we can run? If you can provide the steps on how to use the code you wrote.

Thanks

Hey @Web1017,

All this did was change the process priority.
I haven't played recently, so I'm not sure if it's still necessary.

Hello Francis.

I understand that. Im asking how it's possible to use this code in the game. I believe it's still necessary as the CPU is still being run at "High" and not "Normal".
