With FSO there is no v-sync, vsync is only turned on when there is an overlay that's why i asked if you have tearing it's a simple test.
I Am pretty sure, that there is V-Sync. DWM can, or forces V-Sync in Windowed Borderless! FSO makes game run in Hybrid Fullscreen mode aka Windowed Borderless!!! Words in that article are misleading! Doesn't matter, if you use any overlays! While on the other hand FSE will override DWM:

DWM manages buffer of all windows together, while FSE will dedicate its own buffer for a game! Everyone was disabling DWM in Windows 7, as it cause lag. And FSE was preferred mode long time!
What? How tearing = no vsync???
Yep, but that's Microsoft circle jerking talk and Borderless Fullscreen window = windowed mode without borders! Where DWM can force V-Sync. Also windowed mode is crap and has higher input lag then FSE! I tested disabling FSO in many games and everytime it reduces input lag and makes game much smoother!greenenemy wrote: ↑11 Mar 2021, 11:01From the microsoft blog you mentioned:To get back this performance overhead, we enhanced the DWM to recognize when a game is running in a borderless full screen window with no other applications on the screen. In this circumstance, the DWM gives control of the display and almost all the CPU/GPU power to the game. Which in turn allows equivalent performance to running a game in FSE. Fullscreen Optimizations is essentially FSE with the flexibility to go back to DWM composition in a simple manner. This gives us the best of both worlds with performance and other features that require the DWM, such as overlays. When an overlay such as the Game Bar is present, the DWM reassumes control of the display, and a slight performance overhead is incurred so that the overlay can be composited on top of the game in a safe and stable way.
