In-game AA settings question

Poacher886 · 01-11-11, 01:54 PM

In the game you can adjust the AA slider 5 notches....i dont get this as AA is normally valued at 2x / 4x / 8x / 16x / 32x, i find it very difficult to beleve they are offering 32X AA, so what does each notch on the AA slider equate to??

Thanks

Off-2X-4X-8X-16X perhaps?

Poacher886 · 01-11-11, 02:40 PM

Could be? does any of the modders actually know the answer to this?

I'll keep an eye on this thread, if no one knows the answer, I could test the theory by grabbing a screenshot from the docks with the slider set to left most position and another one with AA forced off in the ATI-tool. The screenshots will have to be taken from the exact same location. Even if no diff can be seen, placing the shots as two layers in PS and using difference as blending mode, as well as tweaking the curve a bit, should bring out the slightest differences.

I ask, because my GTX570@1920x1200, with this setting @Max runs the game fine 45-85+FPS (im using TDW Mega-Mod mind) yet as low as 29FPS if im looking at the ocean bed. This is fine and smooth, but it uses ALL my 1280mb of V-Memory!!

Which i think is contributing to the odd stutter when viewing via external cam. If the Max slider = 16xAA, then that might explain at my res, the high use of V-Mem.

AntialiasingLevel=16; 0=none, 1=non-maskable, 2=2x, 4=4x, ...

Sorry Sober, are you saying it goes like this on the slider.

0 / 2x / 4x / 16x ???

Actually it's 0/2x/4x/8x/etc.

That 1x in the config file is for compatibility purposes only, since it's a valid input for the graphics card.

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

Poacher886 · 01-13-11, 02:19 PM

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.
