Hello, is everyone here using Resolution Independence feature?
Anyone could give an example how useful it is
Does that offer obvious differences when you look at the screen of iphone4, one app with 960x640 Resolution Independence selected, and one app with 480x320 ??
I dont have iphone4 so I cannot test how big is the difference... if that just very small differece and cant obviously distinguish by eyes, why do we waste time to make retina image?

I am just looking for advices..

It makes a huge different when done right. And 8bit retro game won't see a huge different, but most everything else will

It makes a difference. Especially to the younger crowd, and those who are so used to HD nowadays (myself included). I do my testing on my iPhone 4 (mostly), and I can DEFINITELY tell the difference with the images I used that were SD, and the ones that were made for Retina. I say make it work in HD. The new iPhone 5 will be coming out soon enough, so you might as well be at least caught up with the iPhone 4 by then.

I wouldn't expect this years iphone to be iphone 5. I haven't heard of anything majorly different from the iphone 4 I think mostly it will be an upgrade like 3g to 3gs was.

But back to the subject. Yes I think its important and its not like its a huge inconvenience as long as you start your project with the intent of using it. I cant believe anyone doesn't use it now. I mean honestly Why not its just a bigger image. there is nothing else that is different you use the same software, the same art style, its just make it bigger.

Remember that res ind only effects OLDER devices. Here's what I mean. If I double the size of my images in relation to the actor that I am using them for and I don't check the res ind setting it will look great on an iphone 4 and will look normal on a 3gs. The res ind makes a separate normal res image for the older devices so that it uses less ram when loading images on the older device. The idea is that it is a waste of ram to load hi-res images on a device that cannot display hi res graphics.

Thank you all of your advices.

My project is some about one 10 actors team fight with another team. The FPS dropped very fast... I was looking for the reasons what makes FPS drop. Now I realize image size is not the problem... The problem is too many rules appear in one scene, each of my actor has no less than 15 rules, and 20 actors fight with eachother....

I think 20 actors fighting is not a big number in iphone game right?
May I expect the optimization of the rule feature in the 0.9.1

I just tested Alien Breakout (my game) on the iPhone4 and I found out, that the backgrounds look ugly, because the color gradients look like 16 color gif images due to the very sharp retina display. Although this is a bug in the engine, not depending on resolution.

Everything else is looking very good, although the game has no retina display.

So only the backgrounds could use retina display and the workaround making the backgrounds corny a bit to break the gradients.

To be honest, I didn't see any need for resolution dependency.

Actually with the verizon iPhone out god knows what's gonna happen. Ipad 2 might get a retina. But it might reduced to 7 inches. Who know. I guess ri is useful sometimes
