Anybody know if all X360 games so far are all 720p or are there any running in 1080i?

There has been no word sofar :/

IMO, all X360 games will render internally @ 720p, but the analog video out chip will side convert to 1080i.

Apparently, DOA4 was running in 1080i when GameSpot got to see it:

The work-in-progress version we saw was running at 1080i

And there ya go

BTW shog, X360 games can be created @ 1920x540 and output as 1080i without the scaler....that might be what we are seeing with DOA4

Thank you.

Anybody know what res the MGS4 trailer was? What are most PS3 devs shooting for 720p or 1080i? I doubt we see any 1080p games for a while.

Sure, but I think most devs will go the 720p route and then let the analog vid out chip take over for 1080i since that eats ups less room in the eDRAM, and you don't have to code for a second render mode.

Well, the video they were showing at TGS was 720p so I would think thats what MGS4 was running at...

According to DeanoC, Heavly Sword is running at 1080p on PS3...

Will the games look just as good when it upconverts to 1080i from 720p?

So then 1080i is more work for X360 than 720p? Also, how well do you think the X360 will scale 720p content to 1080i displays?

Oh I agree with you 100%

720p>1080i, especially for games....

Won't be as crisp. The video out chip doing the conversion is analog, and conversion in itself will degrade the picture somewhat.

Even if games are developed to display in 1080i instead?

That's totally different.

 

[super-heated plasma]

Thast what I thought. So hopefully most of the big games will outright support it. My TV also does 540 p.

A 720p image wont fit in the X360 frambuffer, but they use early Z-test to assist with deferrerd rendering/tiling (Yes, Dreamcast was also a deferred rendering architecture)and 1920x540 frame is even bigger than a 1280x720 one....so it won't be "more difficult" per say, but there will be a fillrate cost with 1920x540 games....

Since this is so, and since most new HD sets are progressive (either 720p or 1080p) I would suspect a vast majority of X360 games will be 720p...

As far as how well X360 will scale 720p content to 1080i displays, well that depends on the quality of the scaler and no one has gotten the chance to put it to an objective test yet....

 

[Shompola]

the entire frame buffer is not stored in the edram and that has never been the plan... it is only the back buffer that is stored there, and they used tile rendering to fit FSAA in there. Resolution with no FSAA would fit in the edram with ease.

 

[Agent Icebeezy]

Is DOA4 being coded for just 720p or does it include both 1080i and 720p

I thought 2xFSAA was free? And 4x was supposedly "close to free"?

Well, according to Gamespot it is 1080i...

I dont think you will ever see both 1080i and 720p internally rendered X360 games.....

If you ever saw dual native resolution games I would think it would be one SD version and one HD version....the scaler can handle all the rest....

 

[Shompola]

They were probably referring to processing power, I am talking about memory amount.... Memory amount will lineary increase with the number of samples needed. 2x FSAA needs 2x more memory than 1x FSAA etc. 1280*720*(4+4)*(FSAA samples) bytes.

Somebody with MCE can prep some 720p test patterns and 'bouncing ball' animations in WMV, these may be useful for objective testing of output to 1080i display devices.
