Vsync is hardware feature. If you have 75fps in game with vsync enabled, it means the game ignored your desktop settings and set your video adapter and monitor into 75hz mode. Try disabling "fullscreen" option in game settings to keep desktop settings.
When people will stop talking "photorealistic contact size" on PC monitor? 🤦♂️ The game should be playable; the spotting should be good enough to use realistic tactics. When I can't see [edited] i can easily see IRL without getting my eyes hurt - the game is unplayable for me, and most other people. There are simple decision for devs to make: they want people to play their game, or they like fancy talks about "how realistic it looks" by 3.5 remainig fanatics.
