For example, we have several different types of V-Sync that exist: 1) traditional double buffering 2) linear triple buffering like what you can force via the Nvidia control panel in OpenGL games (this one does not toss out frames and doesn’t look as stuttery as Fast Sync, but of course fast sync has lower input delay and can run at arbitrary FPS above monitor refresh) 3) fast sync style triple buffering (sometimes called “true” triple buffering for some reason like in the Digital Foundry video on V-Sync) 4) Adaptive V-Sync, but that’s irrelevant to this question My question is the title, namely does Windowed mode force fast sync style triple buffering where frames are lost/thrown out or does it force linear style triple buffering like they found in the Nvidia control panel? For me, Fast Sync is a hard no-go due to how stuttery it makes everything look and since windowed mode runs at arbitrary framerates above monitor refresh it seems to me that’s what Windowed mode is doing — fast sync style triple buffering I mean, but correct me if I’m wrong there of course. Have I got that right? Thanks! From a pure performance standpoint I’d think you’d be better served by enabling exclusive full screen mode and forcing fast sync via the control panel over using Windowed mode since windowed mode incurs a small performance penalty from what I’ve read. Somewhat related I wish you could force the linear style triple buffering where frames are not dropped via the control panel in modern games, not just OpenGL ones, but alas it’s not to be.
