I bought Call of Duty: Modern Warfare last year, but haven't played it much. A friend reached out to me via Battle.net to ask if we can play a few games and I told him I had CoD:MW.
I started playing the campaign to get familiar with it, but noticed that the game kept crashing after a few minutes of play.
Initially, I tried dialing back the graphics, in case my system couldn't cope with it, but I play a lot of other resource-intensive PC games on this system, so I knew that this wasn't a hardware issue. I had the game redo the shaders, as well. Neither helped. I reinstalled the game (as someone suggested) but that didn't help either.
Today, I fixed the issue. It wasn't related to software or hardware. This was a networking issue. I went into my router's configuration and added some port fowarding entries using this resource. It worked. The game hasn't crashed and I've played maybe 1.5 hours.
