Dropping FPS half time

Do you know what it feels like? It feels like you don't work. It feels like you ignore the minority who are having trouble playing, which at some point is good for you because it's only a small minority. The game has been out for 4 months, and since day one, I and "many" others here haven't been able to come home from work or school and enjoy a game that was expensive. It's completely ridiculous and disrespectful to have to go through these situations. How many games have I already lost or had to quit (even when I didn't want to) because it's impossible to play with 10 FPS? Every time this happens, I have to restart the game, and I can only play for a few more minutes until the same problem happens again.
