1080p without AA >720p with AA. I've been playing on PC for a long time with a mid-end PC, so lack of AA doesn't bother me, but blurred images because of non-native resolutions just kills IQ. AA only blurs the image more when talking about non-native resolutions, so adding it is not making things any better.

Yeah the screen size interferes... good point I missed that one.

PS. I will love to see some comparision like the Crysis

I really don't like upscalers for far good it was... I prefer direct 720p than upscalled to 1080p... I set my TV and PS3 off for upscalling.

aliasing is one of the worst things in my opinion. if you play a game and everything has jaggies it really is annoying.

720p or 1080p depends how close you sit to which tv size. most people i know in real life sit so much away from their 46 or whatever inch screen that they won't see any different at all or only a very tiny difference.

on pc people sit almost always very close to a screen and it will make a big difference for most pc gamers if the screen has a decent size.

but if we talk about console gaming i think anti-aliasing is more important. i really hate it more than most other stuff in games from a technical standpoint. good example are my endless posts about how i like forza games but hate the aliasing in the games^^

In theory the increase in resolution give you less aliasing but that just works using the same screen size... like you said if you start to increase the screen size you wiil need to increase the resolution too to have less aliasing.

I never saw a 4k screen but I guess a 60" 4k screen showing a 4k native game will have little aliasing... so AA won't be needed.

Just to add the HDTVs already do some light AA filter... I tried sometime to output the same signal to HDTV and a PC monitor of the same size (32") and the PC monitor showed more aliasing... so I did some research and the HTDV uses some filters to display the image and monitors shows the native output.

You have to be viewing those images correctly you have to be viewing the, at full screen on a. 1080p monitor. If not you're essentially supers sampling he images.

I think 1080p with no AA looks a lot better than 1080p upscaled from 720p if the textures are good. If the textures are like say resident evil 6 . There's not that much of a difference. But it's still not as crisp. That said just adding SMAA makes 1080p look substantially better without performance hit of msaa or blur of FXAA IMO.

Also I assume we're talking about MSAA Correct? It's nonsensical to super sample a 720p image and if you can do that you can do 1080p with msaa. And if you use FXAA or MLAA and then upscale you'll get extremely blurry textures. 

Wait, so you just have huge black areas around the image?

I couldn't stand everything looking so small, but I agree that the IQ would be better.

I agree: 1080p native without AA anyday
