video tearing and drop frames with HW acceleration

[JuanRugge]

Firstly, please enable HW acceleration and try upgrading your video card driver.
If the issue persists, try appending this command line to "Other settings"->"Startup command line":
--disable-direct-composition --disable-gpu-vsync

all drivers were up to date.
those command lines made the trick. when before i have constant frame drops, now its 1 or 2 only when entering, exit full screen and scrolling.
ill keep an eye if i see tearing.
thanks for your help.
