So, I've just moved from a laptop with an ATI Mobility Radeon HD 5650 graphics card to a desktop computer with an AMD Radeon HD 7700 graphics card. Both run Windows 7 64bits.
My problem is: Whenever I go full-screen with a game whose resolution is inferior to that of my 1920x1080 screen (which is the case most of the time), I get a slightly blurred output.
Technically, that blur is not a "problem" in any way; it's just how the graphics card handles upscaling.
The thing is: I don't want that blur to be there. My laptop always had a perfectly crisp output, which I favor over the blurred on.
I might be saying something stupid, but I believe my latop's GC uses point sampling whereas my new computer's GC uses bilinear interpolation - hence the blur.
That blur doesn't have a negative impact on the visuals of modern games, but it certainly does on games with a 640x480 resolution for instance.
Is it possible to manage the way my GC upscales stuff? And if it is, how?
