I played it for about 4 hours yesterday all together and only had one game drop me. I don't really know what happenedd, my entire computer just shut clear off. I really hope it wasn't a power supply problem. The game ran super smooth and not once since I started palying have I ran into even the slightest bit of lag. It's really weird how different people have such different experiences with the same game. For me it's been great and almost bug free. I have had the fall through the map thing in prone, screen flashing, and screen tearing(switching my nvidia panel to vsync fixed the tearing and almost did away with the flashing), but really that's about it.
I'm finally getting the hang of the game. The game that shut me off, I was 6-1 and on my way to greatness. I can't wait to see this game once they let all the graphics running, becuae right now it looks great. The more I play it, the more I start to appreciate the little things they've done.
I hated rush at first. but now I'm really starting to like it. There's alot of strategy involved and when you get lucky to get into a good game where most of the people are actually trying to attack and defend it is a very intense game. Much more team based then the COD modes.
For all the people who are having such big problems, check out the technical section in their forum. there are tons of fixes you can do to get the game to run better. It is a BETA after all, and there will be problems that you have to work around before you can get it to run right. I've only ever done a few BETAs before, but in all honesty this is the best running one I have done yet. Exspecially considering how they are using a new way to run the game with the battlelog thing. I thought it would be a disaster, but I actually kind of like it. It's so easy to check your stats, friends, forums, etc. Everything is right there in front of you in one place.
