I read that for gaming its better to turn off scaling in the NVIDIA Control Panel?

Also, is Display scaling better than GPU scaling?

    One should -aways- run ones display at its "native" res (set in the NV control panel)
    IE: a 1920x1080 monitor, set to run at 1920x1080 in the NVCP
    As for your questions.. the answer is "tricky"
    For MOST users the recommended setting is Display scaling OFF, NVCP (left at Defalut) scaling set to ASPECT RATIO
    As shown

    For users of non-standard displays (TV's), users of older monitors or users using more than one display (but different ones), and users who have installed "secondary" monitor software (more than the BASE driver) ... the answer is quite complicated.
    In all cases, setting the NVCP to the Monitors "Native" screen res is the fist thing that should be done, as this avoids almost all scaling issues (except those at Boot, when the BIOS and Loading Screens are running at 800x600)
    After the Native screen res is set, then non-standard users must "test" for what settings work best for what programs they have installed and how they use there computer... for what works "best" for them.
    Great question...
    Sorry to give a non-answer, but it really depends on the EXACT setup someone has, as to what setting is best

    It depends on the monitor. Some monitors doesn't scale certain resolution properly.
    Like my monitor stretched 1920x1080 vertically on my 1920x1200 monitor on the default settings. So, I'm using GPU Scaling w/ override and Aspect Ratio in order to get 1920x1080 to force it to scale properly with the black bars on the top and bottom.

    Lets discuss the various options in context of their use.  So let's say your monitor is 1920x1200, and you have an older game you are playing that only runs at, say, 800x600.
    The options you have are:

    Scaling Mode
    Aspect ratio - the image aspect ratio is preserved.  Your 800x600 game is 4:3 aspect ratio, but your 1920x1200 monitor is 16:10 ratio.  So this option would tell the monitor that your game is actually running at 1600x1200...it 'scales it up' to fit your monitor as best it can maintaining the aspect ratio (in this case, the height is the limiting factor of '1200' - if the game had been scaled to your monitor width of 1920, it would be 1440 pixels high...wouldn't fit).  As this doesn't quite fill the whole display, you'll just get black bars on the sides of the 1600x1200 image to fill your 1920x1200 display.  Sort of like letterboxing, but sideways.
    Full screen - as it sounds, it takes the game and makes it full screen.  Your 800x600 game is rendered on the monitor as a 1920x1200 image...which obviously 'stretches' it (makes it wider...circles will appear more like ovals, characters will look 'fatter', etc).
    No Scaling - again, as it sounds - there is no scaling done.  Your 800x600 image is displayed on your 1920x1200 monitor as...an 800x600 image.  Basically, a small window with black all around it filling your display.
    Perform scaling on
    Display - In this option, the video card does whatever is needed based on the above options, and sends that to the monitor as-is.  That is, if you chose 'fixed aspect ratio scaling', your 800x600 image is now 1600x1200 to best fit your 1920x1200 monitor, and so the video card is basically sending the 1600x1200 data to the monitor and letting your monitor figure it out.  Some monitors know what to do with this, and properly display it 'letterboxed'...some monitors are going to just 'stretch' the 1600x1200 to the 1920x1200, anyway (they don't know what else to do with it), and you get the same effect as if you'd set your scaling options to 'full-screen'.  There is really no way to tell what your monitor will do with this - it depends entirely on the monitor.  I imagine some monitors actually provide new features when given this option - maybe letting you choose your own letterboxing color, or deciding how to align the image (off to one corner for picture-in-picture goodness, off to one side, etc).  But, again, it's totally up to the monitor.
    GPU - This is my recommendation for most folks.  The GPU figures out what your intent is, knows what your monitor settings are, and just handles it.  If you have a 1920x1200 display, what is sent to the monitor with this option is always 1920x1200 data.  Whether you told your 800x600 image to be 'aspect ratio' scaled so that it is 1600x1200, or 'no scaling' so that it's really just 800x600...the GPU handles filling in the black 'letterboxing', so the monitor doesn't have to deal with it.  As far as the monitor is concerned, it's just native resolution data, and done.
    Override the scaling mode set by programs and games
    I would leave this unchecked.  Basically, some games (notably console emulators) know they are running at lower resolution than your monitor, and have complex algorithms built-in to 'scale up' images with more smooth curves, organic shapes, better color blending, etc.  The GPU (or monitor) scaling is simply pure pixel interpolation...same thing you get in Photoshop or MS Paint or whatever.  Some programs (again, notably console emulators) do a MUCH more interesting job in making the picture scale up better, and may, as part of that, tell the monitor things about how to scale the image that you probably want to leave as-is.  99% of things won't, so this usually isn't an issue.
    (Of course, you may find something you are trying to play actually DOES try to tell the GPU or monitor something about its resolution or refresh scaling and it's wrong.  In that case, you may want to check this 'override' option.)
    EDIT: In case it isn't obvious, these settings really only have any relevance when playing older games that do not understand your monitors native resolution...most commonly older games that simply assumed a 4:3 aspect ratio on all displays, while most newer displays are actually 16:10 (2560x1600, 1920x1200, etc) or 16:9 (1920x1080, 1280x720, etc).

    GPU scaling will scale your image horizontally and vertically so that it can fit on screen. You should on gpu scaling before start gaming. If you want to know more about gpu scaling then visit below link:

    Gaming lower always want to get best experience for gaming. Resolution is the most important part of gaming, if image resolution is not good enough you can turn on from settings of graphics card. It also clears on screen images, and also improves video quality of games and high definition videos.

    Yeah, probably Display scaling improves input lag
