Like I’m not one of THOSE. I know higher = better with framerates.
BUT. I’m also old. And depending on when you ask me, I’ll name The Legend of Zelda: Majora’s Mask as my favourite game of all time.
The original release of that game ran at a glorious twenty frames per second. No, not thirty. No, not even twenty-four like cinema. Twenty. And sometimes it’d choke on those too!
… And yet. It never felt bad to play. Sure, it’s better at 30FPS on the 3DS remake. Or at 60FPS in the fanmade recomp port. But the 20FPS original is still absolutely playable.
Yet like.
I was playing Fallout 4, right? And when I got to Boston it started lagging in places, because, well, it’s Fallout 4. It always lags in places. The lag felt awful, like it really messed with the gamefeel. But checking the FPS counter it was at… 45.
And I’m like – Why does THIS game, at forty-five frames a second, FEEL so much more stuttery and choked up than ye olde video games felt at twenty?
The latency numbers of displays ie the 8-9 or 40ms include any framebuffer the display might or might not have. If it is less than the frame time it is safe to assume it’s not buffering whole frames before displaying them.
And sometimes less, like when vsync is disabled.
That’s not to say the game is rendered in from top left to bottom right as it is displayed, but since the render time has to fit within the frame time one can be certain that its render started one frame time before the render finished, and it is displayed on the next vsync (if vsync is enabled). That’s 22 ms for 45 fps, another 16 ms for worst case vsync miss and 10 ms for the display latency makes it 48 ms. Majora’ mask at 20 fps would have 50ms render + 8ms display = 58 ms of latency, assuming it too doesn’t miss vsync
