I keep losing connection to host midgame so at first I thought it was my internet connection until I got an error that said context corruption. WTF does that mean? The game runs perfectly fine on campaign.

did the beta work for you?

I have also seen this issue during the Beta also, I still yet to understand if this is a client side problem or server side.
For now I would recommend you right click and select repair install for Crysis 3 in Origin.
Also, do some snooping around in your Crysis 3 directory, there might a log somewhere. Might have some extra information that could be helpful for the Dev’s.

Yes the beta worked perfectly fine for me

I repaired the install and there were no missing or corrupt files. I will restart my router tomorrow and see if that fixes it.
