I've been worried though. It's unusual to go so long and so close to a game's release date without seeing every version, and I've been told several times to expect the PS3 version. But it never emerged. This week at the Game Developers Conference we were made a final promise to see the PS3 version of Crysis 2 after the announcement of its multiplayer beta on the system launching March 15th, and I spent about half an hour with Crysis 2's multiplayer on the system.
The verdict? Not so great, unfortunately. The performance of the PS3 version is pretty underwhelming. The framerate is frequently low and choppy. There are jagged lines everywhere, and shadows are especially messy. There's a muddiness to the graphics that's hard to stomach in the wake of the PS3's other flagship showpieces, and worse, the variable framerate really hurts controller response.
