    Windowed mode = input lag


    In windows 7, windowed mode input lag was fixed by turning off aero. Is there a fix for windows 8?

    Since you did not provide your specs, I have no idea of your hardware configuration; however, if you have NVIDIA graphics, have you tried turning off VSYNC?

    Hi there
    "Windowed Lag" -- not quite sure what you mean by that. Might be something as simple as a Wireless mouse not working properly.

    I think in all the years of using computers I've never had a problem with "Windowed Lag" if it's what I think you mean - except years ago on something like Windows 2000 on an old CRT Monitor where the screen refresh rate was set too low and I could perceive some type of flickering.

    If you've got even a modest NETBOOK with a horrible video chip in it the screen should be fine. Of course if you are using something like RDP - Remote desktop or logging in to a company VPN or some web sites then the speed will be dependant totally on the network and Internet connections.

    Just ensure that your video drivers are up to date and perhaps set on 3D / hardware acceleration if these are available in your graphic settings.

    Very unlikely but if you have a rubbish monitor that could cause problems too -- but that's so unlikely that I think you can safely ignore that scenario.

    Cheers

    Hi jimbo45,

    From what I understand "windowed mode input lag" is a common phrase usually associated (but not restricted to) gaming where one switches from full-screen gaming to a smaller "windowed mode" (for what ever reason).

    Hi there
    What's the size of your Monitor (Full screen) and the resolution of your graphic card.

    If you have say a HUGE 60 inch monitor the poor old video card is going to take a while to "paint" it . It will take a finite time to draw the pixels on to the large screen (and it won't look too pretty either on that size screen either). The time to paint the screen will depend on the power of the GPU (the processing unit for the Graphics subsystem -- not the main CPU of the computer) in the graphics sub system (can be integrated or a separate card) and the amount of RAM the graphics subsystem has available to it.

    A Modern monitor will be reasonably efficient provided the data is fed to it quick enough from the GPU subsystem. These days I wouldn't worry about a "Slow Monitor" although it IS possible. Remember though the data is buffered until the screen can be presented to the user. It's not done "line by line" like the old CRT's did.

    If the graphics subsystem (whether separate Card or built in on the MOBO) has a very small amount of dedicated RAM then it's going to take time to paint any decent full screen image on a monitor and the delay can in extreme cases be noticeable.

    The Graphic sub system's GPU (whether it's on the MOBO or a separate card) also needs to be up to the job -- however these days that normally isn't an issue unless you are an "Extreme Gamer" - which needs specialized graphics amongst other things for playing a lot of modern games.

    If you have an OLDER BIOS in your computer it might be possible to improve performance of the graphics sub system by allowing the BIOS to reserve some RAM for the Graphics. This should only be necessary on quite old machines though.

    Cheers
