Hm, here's a thing I forgot to mention, since it's been a while, as this is from my "good ol' vsync days" without a g-sync monitor.
would sometimes result in "uneven stutter" in some games. For example, imagine the game running at 60FPS for 300ms, then at 40FPS for 300ms, then 60, then 50, then 60 again, then 30, etc. The way I could tell is because once you get that "sweet [email protected]
vsync lock", you immediately know. Even if that happens for only a fraction of a second, you can tell.
Switching to MPRF 1 would result in "even stutter". That is, 40FPS sustained (or 50, or whatever.) Whatever FPS the PC was able to produce at any given time, that would be what I'm getting. Setting MPRF to anything higher than 1 seemed to make the driver or the game trying to compensate for the low framerate. And the result was visually bad.
Now, I don't know if this is subjective or not, but to me, the "even stutter" was preferable to this "severe hiccup stutter" I was getting with [email protected]
Games would seem to "buffer up" a couple frames, play them smoothly, then hiccup as the buffers got empty, rinse and repeat. [email protected]
would give me what I call "good stutter" (an oxymoron, I know), where at least things were consistent, not a mix of "stutter-smooth-stutter-smooth".
I suppose my [email protected]
experience would on paper look like sustained frame time spiking, while [email protected]
would make the spikes seem shorter. But in reality, the former had a much less offensive visual appearance than the latter. If the GPU or CPU (whatever the bottleneck was) isn't able to sustain a high frame rate, the delivery method of the frames it CAN sustain matters. And that delivery is visually less unpleasant (at least for me) at [email protected]
compared to [email protected]
In a 40FPS situation, I prefer getting 40 frames evenly distributed across 1000ms (MPRF 1) vs getting 30 frames during the first 500ms (so that's 60FPS for half a second) and then getting 10 frames for the next 200ms, and then whatever's left for the last 300ms.
The visual appearance of MPRF 1 during low FPS situations is less offensive to my eyes compared to [email protected]
However, all of the above was without g-sync. Just vsync. I'm not sure how g-sync changes the situation here.
