Wider FOVs cause clipping when close to objects/walls, make you see through your arms when performing stealth kills and r_drawnearfov=X changes first person gun view but you need to put it in console every time.
It's obvious Crytek has not had time to think about this issues nor test any FOV aside from default one, but now that the game is running smooth on every platform you where targeting, could you spend a little time fixing this things?
And, while you are at it, if you also fixed the melee bug when reloading a checkpoint and the AI problems (getting stuck by running straight into walls, magically detecting and shooting you through solid objects...) Crysis 2 would become a pretty solid PC game.
Thank you.
