V-Sync actually synchronizes the framerate with the display device's refresh rate so that the frames get displayed at proper times. In practice, this means that if, for example, your refresh rate is 60 Hz but you can't hit 60 FPS reliably, it'll cap your FPS to 30 FPS. And if you can't hit even 30, it'll cap it to 15. Half V-Sync supposedly does exactly the same, expect that the cap is at maximum half of the display device's refresh rate, so it shouldn't solve any problems, I think.

I'd also like an explanation as to why the same problem doesn't apply to consoles because to me it seems like it should. It's exactly the same technology as far as I know.

Also, 30 FPS looks bad on both PC and consoles. More importantly though, it feels bad.

try to cap witcher 3 with the framerate limiter of the game, the game will be capped at 30 fps but it will run like shit even without motion blur because it's just a framerate limiter, after that, use radeonpro double vsync or nvidia's control panel and the game will be smooth even at 30 fps. I did the same with various games, nobody can tell me it's not true cause I did it myself.

I'm not talking about 30 fps looking bad or no, I'm talking about the configuration and why looks worse on pc compared to a console when you use a framerate limiter or when your rig is not powerful enough

I wasn't talking about built-in framerate limiters at any point. All I talked about was V-Sync, so I'm not sure why you're talking about the framerate limiter. I understand why it doesn't look as good when you're using a built-in framerate limiter instead of V-Sync, though (it's because the frames don't always get timed the same as the refresh rate of the display device, which results in slight stuttering). Anyway, I google'd double V-Sync too now, and finally got more technical details about it. Now I can kind of understand why it produces better results, I think. Eh. Sort of. Or maybe not, now that I think of it. Aren't regular V-Sync and double/half V-Sync the same if you can't hit 60 FPS reliably (i.e. if V-Sync limits the framerate to 30 anyway)? The only reason I can think of why you might want to use double/half V-Sync instead of regular V-Sync is when you can hit 60 FPS a good portion of the time, but not always, and V-Sync keeps switching between locking the framerate to either 30 FPS or 60 FPS.

What I mean about console games having the same issue: Don't they use regular V-Sync too (usually)? If so, why is the situation any different to using regular V-Sync on PC? Again, no built-in framerate limiters here, just V-Sync.
