    4K Cursor Lag


    A while ago I've upgraded my Couch Gaming PC with an 4K TV and while it's generally working well I've started noticing what I'd call Cursor Lag and while it's not much it IS fairly noticeable kind of annoying the crap out of me so I've been wondering who the culprit might be.

    System is, what I'd call, a last Gen High end System featuring a not quite Flagship X79 CPU ( can't remember model... ), 32GB of RAM and a 980Ti.

    What bothers me the most is that this Cursor Lag keeps happening even on the Desktop with nothing else running thus making me question cause of it - Lowering the Resolution though appears to solve the issue *duh*

    Is this a general Hardware issue involving the entire System or can this be attribute to a GPU only thing?

    Thanks in Advance =)

    I do not know if we talking about the same thing, but I noticed a system wide Lag, most noticable while lauching a Programm. The Time it takes, between mouse click and it opens, is quite long, and I did have not seen it in other version than Windows 10. For example lauching Firefox, take ages until I can type something. That general Lag I think it W10 related. Well the system where I have w10 installed is quite poor, so I have to be carefull to say it is W10 but it could be my poor hardware.

    @Durahl your system certainly should be able to cope with 4k. Have you installed the latest drivers?


    @Adalwar your situation is different I suspect your lag is caused by old hardware. You don't have much ram either which would cause the pc to swap out its memory to the hard drive. Because its a old laptop, I suspect the hard drive is likely to run at 5400rpm so that would be another bottleneck. All these things together probably cause the lag. The lag certainly isn't Windows 10 related.

    Three options I can think of: 1. Consider getting an SSD, 2. consider at least doubling your ram, 3. just accept the laptop is old and slow and start thinking about replacing it.

    Well, RAM I have 1,1 GB free in System, that is not the problem.
    I have a eMMC 32GB Drive and it is quite quick, so that is also not the Problem.
    Maybe Processor is quite Slow, but I am not sure that it could cause that Lag.

    EDIT: Swapfile is 704MB.

    I think some kind of lag is normal for TVs.

    This is why they usually have a 'game' mode which bypasses most or all of the picture processing. Try that!
