Slight input lag while running two monitor set-up and CS:S on laptop screen.

Hey guys!

whenever I play CS:S I play in windowed mode so I can play while watching reddit at the same time on two screens. One for CS:S the other for Reddit.

The resolution is the same.

When I'm playing CS:S I'm not having any fps issues but my mouse has slightly noticeable lag. This only happens when I run it in windowed mode, while it's fullscreen the mouse doesn't lag. It's very slight lag but in a game like CS:S it's very annoying.

If I run on Fullscreen I can't have CS:S open on my second screen, it'll get minimized and the point of two screens is to have them both opened.

My laptop is in my sig I think it should be good enough to handle it.

I run both 1920 x 1080 resolution. I play CS:S on my laptop screen and other stuff such as webpages on my other Samsung LCD 24".

Thanks you!

EDIT: It's definitely not because of the USB. It's a wires mouse razer death adder 3.5g.

EDIT 2: The only thing I have changed is that I replaced the HDD with a 64gb Samsung SSD. I now use my main HDD as external for games, movies, and music I also have steam on their. But I don't think it's a HDD issue.

EDIT 3: It could be the sensitivity, testing this right now.

 

Anyone know what could be causing the lag?

Thanks again.

 

Tried to recreate the issue you posted but cant seem to get the same mouse lag.
But it could be either tied to mouse accelleration or raw mouse input that some games got an option for.

Maybe try disable Aero.
