Games at non native resolution. Upscaling? (Clevo W350ETQ)

Hello, my laptop screen is native 1080p, but some games are just too demanding to be ran at that resolutions without turning down all eye candy. So i tried running the games at 720p instead, the framerate drasticly improved, but the setback is that the image get's very blurry. I know that this is caused by interpolation, and that lcd screens generally look bad when not using native resolution. But there's one thing i don't understand.

I have a PS3 it's hooked up to a Samsung 1080p television. Many PS3 games doesn't run at 1080p but at 720p, yet it looks very sharp on my tv, i guess the TV upscales the 720p to 1080p.
Why can't i do this on my Laptop? Is there any way to run games at 720p and make the gpu Somehow upscale it to 1080p to make the image appear less blurry?

Would love to be able to Play Far cry 3, at 720p without the blurry image, as this resolution let's me enable all eye candy, and still have a good framerate.

 

well what u COULD do is choose a resolution that would match a whole-number divider of FullHD resolution.

for example: 1920x1080 as FullHD, divide that by two and ull get 960x540. at that resolution u wont get any or at least not nearly as much blurring cuz each software pixel is shown on exactly two display pixels (as opposed to a factor of 1.5 when comparing 720p with 1080p).

aside from that u can just scale down antialiasing (AA) and anisotropic filtering (AF) for a considerable performance boost at practically no loss of image quality whatsoever. unless of course ur gaming with a magnifying glass on top of ur display...

 

There are scaling options, have you tried turning the resolution down a bit to say 1680x1050 and putting in some black bars instead?

Or applying AA to the lower resolutions can also help but this less so for textures.
