Windows 10 Build 17134 60fps feels like 30fps in borderless window mode vsync off

[intes2015]

I have this issue in all my games when in borderless window mode vsync off my fps is at stable 60 (capped it using rivatuner) but when i move my camera around it feels like 30fps. What seems to be causing this?
I don't have this problem when in fullscreen mode, but some of my games freeze/crash when i alt-tab while in fullscreen.
Turning vsync on in borderless window mode also solves the problem but I wanna play with vsync off.

Never had this issue with Windows 7, is this a common Windows 10 problem?

PC specs:
i7 4770
MSI Z87-GD65 (latest bios)
16gb ram
GTX 1060 6gb (416.34 driver version)

Which version of the BIOS are you on? What are the specs to your ram? I find it odd that you have a Z series chipset but a non K suffix processor. You could try and uninstall and reinstall the GPU drivers. You also didn't state the make and model of your PSU. Please include the age of the PSU as well.

bios version 1.C
G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800)
Silverstone 600w modular PSU (2 years used)

Will try to reinstall gpu drivers later, not at home yet. Will update this thread 6hours from now.

This issue only happened when i switched to Windows 10, back when i was still windows 7 i can run everything fine with borderless vsync off.
