Do you lack FPS in Warzone (Modern Warfare)? If so, then I want to recommend this FTP guide made by Panjo. I have used this guide myself and have increased +40 in FPS in warzone.
There is a lot to fix and you will certainly make changes that you have never done before in Windows. So, before you start, you must make a restore point in windows in case something goes wrong.
But do not worry because I am sure it will go great and if something should go wrong then you have made a restore point.
If you have any thoughts or questions, I will be more than happy to help. Just comment on this article.
