Sorry I didn't know how to title this post as the issue is a little more specific.
In my main game, Rainbow Six, there's no really efficient way to practice so I wanted to practice in CS:GO.
In converting FOVs I found I was setting my CS:GO config FOV to Rainbow Six's actual FOV.
I've felt no difference but I wanted to make sure for ease of thought and so that I know in-case there really is an issue.
My stuff is below here, I thank anyone who helps me in advance
