do you think if you changed a 30fps games rez from 1080 to 720 ud get double the performance? dude is right ud get like 10fps max

Why yes!

This is generally a very misleading post. Just so much misinformation here that I can't get into.

AA isn't just a button press away from fixing everything. The more geometry on a a scene, the more jaggies there will be. The lower the resolution, the more noticeable said jaggies will be. To get a 576p crysis game looking as clean as it running at 1080p, the amount of resouces you would use for just the AA would be more than you would have needed to just up the resolution.

Lets not forget that lower rez also means lower overall clarity. Its easy ok looking at 480p on a 4.5-5" screen and saying its ok, but just ry blowing that up to 46" or 50" and it will become a horrible mess.

Besides, the whole point of AA is to eliminate jaggies thus cleaning up the image. The funny thing is, the absolute best type of AA is something called supersampling. What it basically does (for a 1080p image, you can apply this to any resolution too), is that the GPU renders your the game internally at 4K (1080p x 4) or even 8k. Then it downsamples that render and outputs the downsampled image at 1080p. Whole point of this is cause the higher up you go with rez, the less you will need AA. Problem with this is that its also the most expensive type of AA.

TL;DR? You use lower rez, you spend more on AA. Use higher rez, you spend less on AA and improve the overall clarity of the image.

The idea of dropping resolution is horrible.

Image quality is the most important part of graphics IMO. High resolutions and good AA, nothing tops a clean image.

I understand and technically there isnt much to disagree here but it still is possible to have some simple configuration options. We have seen many examples of this before. The thing is, it just takes more time and effort to optimize for more than one setting. It is almost like optimizing the game for two different patforms.

You heard it here folks. Games that have lower resolution can't possibly run at higher framerates than if the same game was developed at 1080p. Nope. PC gamers can't change their resolution in game or remove graphical effects to increase framerate. If the game runs 1080p@10fps, nothing you can do will increase that fps, and according to one person, reducing framerate will actually lower it.

For consoles I'd assume the game is built to run one setting and the resolution is dependent on your television or what you set it as and that's why reducing resolution won't increase framerate. If the same dev was to port the game over for 720p instead of 1080p, I'm sure they'd be able to get 60fps out of it. Or maybe all the devs that have stated that they'd have to decrease resolution to keep a stable framerate are just talking out of their asses? What do they know about developing games anyways?

Cause that's totally what was said?

again, the difference is not big enough. we're talking an average of 5-15 frames gained depending on the game. Which is why a 30fps game would remain 30fps. Unless it was running at ~50 with a 30fps cap. 

Infamous SS at 720p would not run at 60fps. Without the 30fps lock it averages at about 35fps. 720p wouldn't bring it above 45 or so.They'd have to further downgrade other things to bump it to 60.

Well you are actually right. An maybe I was a bit excessive when I said its not possible. More like its not necesary or efficient use of time. Cause you also right, its almost like optimizing the game for two different platforms. And the amount of man hours spend to do that could be better spent on just optimzing the game some more to get the most outta the one platform. 

On consoles the only real way this can be done is withhaving things like 2xAA, 4xAA, locked or unlocked framerates and maybe a rez toggle. everything I listed out there with excpetion to framerate and rez are post porocessing effects. And playing with the rez/framerate can give you gains with the AA. Thats basically all they can really do on consoles. On PCs, devs still optimize for a certain minimum spec they have in mind. But the unlock everything and allow the gamers set however well or badly they want the game to run.

Can't do most of that on consoles cause well, if someone increased the texture rez on a console from say 2k to 4k then you would instantly need twice the amount of memory for textures. That would just break the game. 

You cut out the portion how I said the games on consoles aren't developed that way to make your case?  Awesome. 

Anyways, even if I don't know anything about game development, I know a thing or two about math.  You have 1080 pieces of something and only use 720 pieces, you still have 360 pieces left available for use elsewhere.  Add that together with the many devs who have stated that they need to reduce resolution to get it running at a good framerate on PS4 and Xbox One, or maybe even take a look at games like Rage and Wipeout HD which drop resolution mid game in order to keep framerate at 60fps.

I am gonna say it... 80% is not more people will not notice the difference between 720p and 1080p unless their TV is <36in at least. Yes, you guys can argue with me telling me you see a difference because you think you see one, but you really don't. I'd be willing to bet that if you took something at 1080 and something at 720 and looked at them (without knowing which one was which), you'd be guessing which one was the higher resolution.
