So the options they are working for post-release patch are...

792p with 2xMSAA
900p with FXAA
1080p without AA

For now I think they choose the first option due a better framerate... after optimizations in code they will chosse the later two... which one is better? I really don't know.


As far as looks 1080p with no AA will look better than the other 2 options overall. Resolution is pretty much the "end all" when it comes to looks. But if it injured the frame rate I would go with the 792p with 2x MSAA.

But seriously 792p with 2x MSAA? My laptop could run it at 792p with atleast 4x MSAA.

From what I understand the MSAA is processed in the render time when you created the framebutter... so they need to do that in the eSRAM that is small... so the MSAA uses a lot of space in the eSRAM...

FXAA is a post-processing AA that uses little space in eSRAM... so using it they free up the eSRAM space to up the resolution to 900p.

Without AA they can go up to 1080p.

From what he said you can fill the 32MB eSRAM with: 1080p noAA or 900p FXAA or 792p 2xMSAA.

That's what they archived in tests... of course they can try to optimize the use of eSRAM to reach something like 1080p FXAA or 900p MSAA... I don't know it is possible but I think they will try.

AnandTech said in a article that 1080p 2xMSAA needs close to 60MB of RAM storage for the framebuffer... to reach 60fps you need to use eSRAM because using the DDR3 for framebuffer the data won't be ready in time for 60fps.

FXAA uses very few resources, they must be really stretching it with the 1080p with no AA. If you were running a game at 1080p with no FXAA at 45 FPS you would run it with FXAA at 42-43 FPS. But that is GPU rendering not memory rendering so I guess it is different. I have 2 GBs of GDDR5 ram in my GPU so I never have to worry about that.

 

Does anyone know how much memory AA actually uses? I have never looked into it

 So far we're not 100 per cent happy with any of the options, we're still working on it. For day one it's not going to change. We're still looking at it for post-day one. We're likely to increase resolution after we ship."

"A lot of the performance is on the GPU side. There's still room for optimisation and we're still working on it," Baker commented. "Ideally it would have been a rock-solid 60 all the time when we shipped but obviously when there's big fights going on, lots of particle effects, lots of physics objects... we're still working to condense the systems, make them more parallel so we can hit 60 all the time, ideally."

Titanfall rushed?

Some research give these render tragets...

1408x792 2xMSAA ~17MB (colour buffer + depth, 32bpp)
1920x1080 noaA ~16MB (colour buffer + depth, 32bpp)
1920x1080 2xMSAA ~48MB (colour buffer + depth, 32bpp)
1920x1080 8xMSAA ~189MB (colour buffer + depth, 32bpp) UNCOMPRESSED

 The 189MB for 1080p 8xMSAA I found here: http://books.google.com.br/books?id=TUuhiPLNmbAC&pg=PA224&lpg=PA224&dq=1080p+render+target+MB&source=bl&ots=mRQd7lK49w&sig=Tv4D4bfqL0po_vR_inDR24Oc0Ss&hl=pt-BR&sa=X&ei=E-MdU_GhDNG4kQfj3YCgBA&ved=0CDsQ6AEwAQ#v=onepage&q=1080p%20render%20target%20MB&f=false

MSAA makes a far larger difference than I would have guessed. Guess 1080p with 4x MSAA will never happen on the one =/

I just read that Jeff confirmed "frame rate drops to single digits and tearing in the final XBOX ONE release".

DUP OMG!!!

Single digits?........ Seriously?.......... they may just need to do 720p with no AA lol



SandyVGina on 10 March 2014

So frame rate is NOT king! These are the developers that used to scream at the top of the mountain that it was. If frame rate was king they would of dropped it down to 720p.
