[Feature Support] Anisotropic filtering

[NineKain]

Makes textures look nicer for almost no performance loss

[elishacloud]

Yes, I added anisotropic filtering to Silent Hill 2 in a previous check-in. It does make many textures look better. However, there are a good number of the textures throughout the game that have transparent edges and this causes ugly lines to be seen in these textures. We tried to find a way to filter out the textures with transparent borders, but that was deemed as not feasible. So at this point there is no way for us to add anisotropic filtering without also adding ugly artifacts to the screen.

So I'm guessing forcing it driver-level has the same down-sides?

At least for Nvidia, I don't believe forcing it at a driver level works, strangely enough.

[elishacloud]

Yeah, same issue at the driver-level.

Also, the same issue happens with edge-anti-aliasing, but on Nvidia there is a transparent option that fixes the issue for anti-aliasing. But it only works for Nvidia. However, with anisotropic filtering there is no such option. It's too bad because there is quite a bit of improvement with anisotropic filtering.

Here's an example of what AF was doing:
