You must know that fullscreen optimizations are a hybrid full-screen mode. The mode does not necessitate desktop compositor and this constraints triple-buffered V-Sync to be used. It also adds a latency frame to the games. The current presentation mode doesn’t care for the compositor, and it decreases latency, thus allows you disable the V-Sync. It also lets fast Alt-Tabbing if there is no display mode switching.

About Sunita
Love to play with Windows 11 and 10. Suggestion - Going for Registry change or system files edit then remember to take a backup or create a restore point before Starting.

  1. Sunita, I have a problem with FSO. I was using this setting on TW3 because it actually made the game super smooth and I was getting 16.6 ms frame times with v-sync active. I was happy, the game had no stutter and was playing really well. But then FSO for this game stopped working, COMPLETELY. It happened after I took a screenshot with Nvidia Ansel, after that, the game somehow now only works in Exclusive FullScreen mode and not with FSO; thus making my frame times a bit worse, at least in the case for this particular game. Other games are fine; I can enable or disable FSO for them and they respond to the change.

    TW3 got FSO disabled permanently after I used Ansel. I know this doesn’t make sense, but this is what happened to me, the game managed to break FSO for good and now it doesn’t allow me to choose if I want them on or not. I am clueless, please help me!
