For the past few months now, 60% of the time I reconstruct after dieing, my game goes in a 5 minute black screen phase, then crashes. Also, I have been getting sever lag, hardly able to move in a straight direction for more than about 15 m. What could be the cause(s) for this? It all started around the time I changed my screen resolution, but I don't know why that would have anything to do with it. Then again, I don't know much about computers, so... Any help?
