its generally closer to 2 frames with V-Sync [1][2]

It actually is fairly significant. LTT did a series of tests with pro players in CS:GO focused on monitor refresh rate, but one test they did was 60hz/60fps vs 60hz/300fps and found that reducing the render latency drastically improved performance despite the display still being locked to 60hz.

Their definition of triple buffering is one of following: One is FIFO, used by Microsoft, which causes even more lag than just double buffered. The other is some obscure mode I barely even remember that is incorrect because it drops or doubles various frames.
