From what I've seen it's 60 fps. Where did you get 30 fps from?
The only place where I've seen 30 fps being mentioned was when they said that you can switch Portal 2 into 30 fps mode to get longer battery life (which is a Portal 2 feature available on PCs from the very beginning).
Yeah I mean it's a PC. Depending on the game it will run at 10fps, 30fps, 60 or 1000fps. No idea why OP would say 30fps specifically. There will be games which run at that, there will be games which runs a lot better.
....yes? It will still run something like CS GO at 500fps+, and I imagine some modern games it won't run smoothly at all. I'm just saying that giving an arbitrary number like "runs games at 30fps" is super unhelpful.
Count the frames on the Control gameplay, the game Valve decided to plaster in every single shot on the website and in the IGN "hands on". Its running at 30fps with drops all the way down to 10.
