G-sync and variable frame times causing undetectable stutter?
Posted: 07 Jan 2021, 19:16
As I was recently tuning a game to run as consistently as possible on a G-sync display, I noticed that things weren't exactly as smooth as I had expected, even though no frame time indicators would suggest that the game had any trouble keeping up.
Then I thought to myself how the nature of G-sync may be the culprit of this visual inconsistency. By keeping an eye on the GPU usage, I could infer that sudden shifts in frame rendering times would defer or hasten any subsequent display refresh, creating what unmistakably looks like a microstutter. As long as the rendering load is consistently low or high, everything looks normal.
How does one minimize this effect when using framerate caps?
