Hlf-Life 2 e FSAA

[Neo]

Gary McTaggart,ha dichiarato che solamente le schede basate sui chip di ATI 9500-9800 sono in grado di utilizzare il FSAA senza la comparsa di artefatti.
testo originale:
There are problems with the way that current hardware implements FSAA. If you enable it, you will see a lot of artifacts on polygon boundaries due to the way that they sample texture subjects with FSAA enabled.

We are working with the hardware companies and the DirectX team to make sure that future hardware doesn't have this problem.

(As a side note: ATI hardware actually has what we need to do FSAA, but it isn't exposed in DirectX 9.)

...Drivers aren't likely to fix the problem, with the exception of the ATI 9500-9800. There's hope there for being able to use FSAA properly. You are out of luck on NVidia unless either NVidia or us come up with some clever way of solving this problem.

...It's a problem for any app that packs small textures into larger textures. The small textures will bleed into each other if you have multisample FSAA enabled. The best thing to do right now is either buy an ATI card in the hopes that it will be solved there, or wait until the next generation of cards come out.

...no current hardware will be able to do FSAA with HL2 as it is now. We may be able to get FSAA working on ATI 9500-9800 somehow.

Centroid sampling (which is the missing feature that makes FSAA work properly) is probably exposed in OpenGL. . I'm not sure. It *is* exposed in DirectX for hardware with pixel shader version 3.0. (All DirectX 9 hardware so far is at most pixel shader version 2.0.) We are sticking with DirectX for the foreseeable future.

Altra tegola x nvidia....
Spero(x loro ) che con nv40 rialzino la testa.

Sì, però dicono che si può comprare una ATi 9500-9800 nella speranza che almeno lì la cosa venga risolta.

Quindi non è che sia proprio una vittoria...
