visual c++ - DXGI Presentation Max Frame Latency -

for apps present interval of 1 , interacts user input, trying understand if there's motivations/scenarios set max frame latency > 1 via idxgidevice1::setmaximumframelatency. it's clear benefit of low max frame latency reduce latency of user input, it's not obvious me scenarios warrant max frame latency of 2 or 3. wouldn't fps because @ steady state, app can queue additional frame anyways since has wait displayed frame finish.

if has ideas this, that'd appreciated. if can outline scenario higher max frame latency helps :)

thanks.

the link documentation posted explains situation when may want use higher frame latency:

it beneficial applications have no user input (for example, video playback) queue more 3 frames of data.

if cpu able process many frames in advance, may provide opportunity use cpu cycles in subsequent frames other tasks, while gpu catches up. may useful if cpu load produce frame unpredictable.
