| sc94597 said: Consoles don't support v-sync, from what I recall. You'll have a lot of screen tearing if you run the game on a 30hz/60hz display at anything that isn't an even or half multiple of 60. Basically the 60hz means the screen refreshes 60 times/second. If you have an fps locked at 30 you'll have a frame for every other refresh. Or if your television supports 30hz, you'll have a frame for every refresh. Now if you have say a framerate of 40 fps, every so often you'll have an extra frame that occurs in between two others (rather than there being a frame every other refresh.) This leads to tearing of the image where your eye sees part of the previous and next frame. There are techniques that can accomodate for this in PC gaming, since they can't really lock framerates for all PC's. These are called v-sync, g-sync, etc. For consoles, however, if a game is 40 fps they'll have to accomodate for this tearing some other way, and in many cases they might not be able to without expending more resources which would bring down their framerate to 30fps anyway. So usually developers either lock their game at 30 fps or 60 fps. And if it is 30 fps they provide more graphical features. |
Just a correction, they do. Killzone Shadow Fall and InFamous: SS are just two examples of games using adaptive V-sync because of their flutuating framerate (40-50 fps). Syncing frames is just software, you can do it even on Android if you want.
About fps locks, a lot of PC games do just that when you turn V-sync on lock at 60 or 30 and call it a day. It's a sensible solution since flutuating framerates won't bring just tearing, but stuttering too and that's way more annoying.
