The game runs like crap on my PC, around 60 solid fps on max settings. While CoD4 runs on like 250. Other than that, I really hate the getting killed game mode, I mean rebels on AT-AT map, since it requires coordination. Joining as a lobby works fine, although it gets a bit buggy when someone else is already in a game and can't join into your lobby... oh, wait, that's not a bug. Fullscreen, windowed mode and borderless fullscreen works just fine. The game is just good!
Aaaaaaaaaaanyway. That was my experience. My main issue is, if this game will have enough gamemodes/maps to justify it's full price. And we can't see that in beta, so yet again, gotta wait for release... Let's hope it's not another Titanfall, that showed everything in beta and had nothing new in full version.
