[Solved] Not responding when sending client info then crashes

If you are tabbing out, it will be because of this.
I also have an AMD, and experience this exact issue. My fix was putting the game in Windowed mode and then just not tabbing out (I put a YouTube video on my second monitor to watch while I load in)

AMD is not the problem. I tab out all the time with AMD for my CPU. So why would you experience something different to me if you have said the problem is AMD as a whole?
OT: I don't really know what's going on, just don't tab out, if you are and see what happens.
