[fixed] figured out why borderless window fixes framerate stuttering in many games Has anyone figured out exactly why borderless window fixes framerate stuttering/drops in so many games? The problem I'm describing looks like low fps even though a framerate indicator shows 60fps -- for instance in darksiders 2, when i stand still and move the camera around, the scenery that is in motion sort of moves in a slightly jumpy/stuttery way, rather than perfectly smooth, as if frames are being skipped , resulting in a low fps look to the motion. It seems like there must be something wrong with the way windows 7 handles fullscreen games , because so many games framerate drops and stuttering are fixed by using windowed mode and d3doverrider to force vsync? Two examples are : 1) skyrim, the camera panning would not be perfectly smooth unless i ran it in windowed mode, and same thing happens with 2) darksiders 2, the game was extremely choppy until i ran it in windowed mode, using a borderless window app to make it look just as good as fullscreen mode and forcing vsync on , triple buffering off , with triple buffering on forced in nvidia control panel, as described here: http://bitmapstudios.com/?p=1584 lots of people reported doing this trick to fix stuttering in sleeping dogs and dark souls, also. my question is, what is the real reason so many games have this problem with full screen in win 7? is it a problem with directx and win7 fullscreen mode, and could we inform microsoft of it so they patch it? btw, this guy wrote a nice borderless window app here: http://forums.steampowered.com/forums/showthread.php?t=2675769 edit: since I posted this , i bought sleeping dogs on steam sale, and this title definitely suffers from the same problem of fullscreen stuttering, even worse than darksiders 2. running it in fullscreen windowed makes a huge difference. you can read about it here: http://forums.sleepingdogs.net/viewtopic.php?f=5&t=1596 update : FIXED! adaptive vsync helped but did not completely eliminate the stuttering with my GTX 670 4gb SC card, the final solution was to download an tiny program called d3d antilag from here: http://www.kegetys.fi/dl.php/d3d_antilag101.zip the game is smooth as glass now!
