games in window borderless lags on dual monitor setup

[wolnavi]

hi. my friend recently got a dual monitor setup. but when we set to window borderless for bf3/bf4/csgo/dota2 on the primary screen and google chrome to the secondary monitor, no matter what game it was, it will have a visual lag although nvidia shadowplay fps counter shows it as not laggy (around constant 70?).

 

is there any way to fix the lag?

 

his specs are

i7 4770k

MSI Z87-GD65 GAMING

8gb ram

MSI GEFORCE  GTX 970 4GD5T OC

windows 7 ultimate 64 bit

 

his primary monitor (just bought not long ago) is a ASUS VX228H

and his secondary monitor (his old monitor) is a Samsung SyncMaster S23B350

 

we tried to change cables, tried to use intergrated graphics for the secondary and 970 for the primary, update graphic drivers to the latest(both 970 and integrated) but it all doesnt work...

 

everything is stock, no overclock (except gpu which was factory overclock)

 

fullscreen doesnt lag, only window borderless

 

thanks in advanced
