In-game AA settings question

Poacher886 · 01-12-11, 12:11 PM

Oh dear, im not convinced on this,

Lets take this from the top.
The AA slider has five settings from 0. Going by what your saying that makes it 0-2x-4x-8x-16x-32x AA, and unless someone can convince me otherwise, i refuse to accept that a game that does'nt even supply AF settings is offering 32xAA.

An amount i've never seen in any game in over 20yrs of playing them!

Then I'll have to look closer into it, i'll let you know.

BTW, some of the newer GPUs offer 32x AA + the game doesn't supply AF settings, but it's enabled by default

I realise that modern hIGH-END gRAPHICS cards have 32xAA..my GTX570 does!, but this is normaly offered as a special feature of high-end cards and requires to be fed via the drivers. For a game to offer this is unheard off by me!

As for the lack of AF option, i've heard that it is enabled automatically...but at what level..8xAF? / 16xAF? who knows.

AF = 8x

I have 16xAF forced on through drivers anyway. Interestingly, before setting off for a campaign while in the U-Boat Pen, i took the FPS @ Max AA slider, then took it down one notch and checked the FPS...it was exactly the same!!

Now if this was coming from 32X or 16X or even 8X i would have expected a noticable difference.

Im amazed A. the game does'nt actually state the AA value and B. No-one has questioned what the values are to date!

Perhaps because most of us just turn it up as high as we can until it affects frame rates. My slider is maxed out. Whether that is 16x or 32x to me is just semantics.

OK I have looked into it and (as some of you have noticed) it actually is:
0x 1x 2x 4x 8x 16x (max 16x)
Where 0x and 1x mean NO antialiasing. That must be a bug which relates to querying the video card's AA settings, where 0x and 1x are listed as valid options.

About the AF filter, the reason why you're not seeing any performance changes is that the texture filtering is not the bottleneck, so therefore no performance can be gained/lost from changing it.
