I recently read that DriveClub is currently running at 30fps but the developers hope they will be able to get it up to 60fps by release. This made me wonder why developers don't lock their games to something in between, such as 45fps.
From what I understand, most games that can't hit 60 lock at 30 instead of running unlocked due to vsync/tearing issues. Wouldn't locking at 45fps negate the vsync and tearing issues that an unlocked framerate would have since it's exactly 3/4 of the common 60hz refresh rate? It would give the developers a nice middle ground between graphics and performance.
Maybe I'm just ignorant as to the true reason they lock at either 30 or 60. If so, let me know.
