Transparency anti-aliasing?

[Mr Fujisawa]

the source engine uses integer HDR i believe, which can work with AA fine, its when using floating point that nvidia cards cant do it with brute force AA (ie flicking on MSAA in control panel). the developers could write the AA code in their engines and it would work (see the luna and mad mod mike demos) but its a lot of extra effort. bethesda said to get the ATI cards to work with AA and hdr wouldrequire more time to get running quick, and they dont want to delay the game jsut for that, although some say its because its an nvidia "the way its meant to be played" game that we arent seeing it

the 360 has both hdr and AA i hear, probably because of the 10mb edram and surrounding logic processors that provide 'free' AA. im getting the 360 version.

There are two types of HDR. Integer and FP16. FP16 is superior.

HL: Lost coast uses Integer, which can be applied at the same time as AA on BOTH nVidia and ATI cards.

The better implementation is FP16, but in nVidia hardware this needs a resource that would be in use by AA at the same time, so you have to chose one or the other.

In Oblivion's case, supposedly AA + FP16 would just make the game slow beyond beleif so the developers decided it wasn't worth the extra development time (delay) to implement the changes needed for both to work at once. On the xbox 360 however, there is no performance hit when running AA at a low level (2x i think?), so I guess in the case of the 360 it was worth sorting.

A little annoyign given that even though current PC may struggle a little with both, a year down the line people playing the game may have hardware that is capable.

They have said there won't be a patch to fix thid however as it would require substantial modifications to the game engine.

In a years time maybe we will have cards that are capable of FP16 HDR + AA

depends. D.P. is always on about how it takes 2GB of vram to do it properly. I doubt 2GB will be on cards in 2007.

I doubt 2GB will be on cards in 2007.

In Guru3D's review of Cebit he mentions that 1Gb cards are on the way

It wouldn't surprise me to see 2Gb cards late 2007

1gb cards are dual gpu.... so each gpu (i think) can still only reference 512mb of memory. I know that the X1xxx series can reference 1gb, but I dont think its even close to being value for money yet.
