I've been a PC gamer my entire life, 30 FPS is perfectly fine for 90% of games(ie, not Fighters/DMC esqe titles)
60 FPS is always preferable but it's very easy to go between 30 and 60.
All of this will be irreverent of course when the game comes out and works fine at 60 FPS.
Opinions, how do they work? It's hard as fuck to change, not something I can do at all, and every game is MUCH better at 60FPS, no matter the genre.
