Is Gaming in 960x540 possible? How is the interpolation?

    There are lower end GPUs like the 940mx, mx150, 1050 gtx which could profit a lot in performance if they played games at 960x540. Obviously 960x540 is also the resolution where pixels from the (mostly default) 1920x1080 could be scaled by a straight integer value.

    Now I have heard that Nvidia allows to create custom resolutions in the control panel, which can "force" some games to play at that resolution.

    But can someone with actual first hand experience answer the following questions?

    a) Is forced downscaling to 960x540 possible in common 3d titles?
    b) Is this downscaling possible on a laptop screen? (I've read that sometimes IntelHD may prevent it)
    b) Is the image quality sharper than downscaling to 1280x720?

    I'd rather play at 30fps @ native 1080/768 than 120fps @ anything lower. Really, non-native resolution reduced to that extent just results in a horrible blurry mess that is more akin to torture than entertainment.

    You didn't understand my question:

    Scaling from 1920x1080 to 960x540 is a ratio of 2:1 in width and height. This means a 1x1 pixel in 960x540 resolution can be projected exactly to 2x2 pixels on 1920x1080, which means that the rendered image should look crisp and clear.

    Scaling to resolutions like 1280x720 have a ratio like 1,3:1 (or something like that) in comparison, and that's why the rendered image looks blurry.

    The questions is, if the image is really sharper on 960x540 than on 1280x720, or if they still use cr4ppy interpolation algorithms, which make the 960x540 image more blurred than necessary.

    At that resolution, even with proper scaling, it's just too low for it to be even remotely crisp. Even at 14-15" it's just unbearable to look at anything sub 1366x768 without having pixels the size of cookies on your screen.

    Isn't 540p the native resolution of the PSVita? If that's the case I suppose you can comfortably game at that resolution, if the screen is 5". For a proper laptop screen/monitor, I'd say 540p is rather unsightly, to say the least.

    It would be very kind if someone could just try it out... forcing a 960x540 resolution via Nvidia Control Panel, and test if it applies in the game, and then report if it's sharper than 1280x720. This would be much more helpful than any speculation.

    I would do it myself if I had a laptop with sufficient specs, but I haven't. My rig is ancient... next purchase is "around the corner" (keep saying that for months...), so I just hoped someone could clarify that inbefore, so I could be more flexible in my choice of low-mid-range laptops.

    Running 720p on my 2560x1440 external monitor looks pretty bad. Doing the same on a native 1080p display will be worse.

    Ok, for your screen with a native resolution of 2560x1440 the question is:

    Does 1280x720 look sharper/more crisp than 1600x900 or 1920x1080?

    No, no it does not. There is no real magic here, anything non-native will be blurry and the lower it goes, the worse it gets.

    That is bad... very bad. That means they apply the same interpolation algorithm even if they could render exactly 1:4 pixels.

    blargh :eek:... where is that puke emoticon when you need it?
