Hi, first post on these forums, but I thought I'd share my findings :smile.gif:
I've finally managed to get full blown multi sampled anti-aliasing and anisotropic filtering working in minecraft, and discovered the following things:
* It makes a HUGE difference when looking off into the distance, it just makes everything look so much nicer and natural, be you running the vanilla texture pack or a photorealistic one at 256px
* Due to how minecraft's rendering engine works, it creates a lot of artifacts around blocks etc. and shows odd lines between individual blocks. This is because minecraft renders every block seperately, meaning that rather than the anti-aliasing affecting only the edges of a surface, it affects the surface as a whole, which makes it so the blocks don't seamlessly line up any more from certain angles (especially when using edge-detect AA.
* Especially higher resolution texture packs NEED anisotropic filtering and mipmapping, it's basically the only way to take advantage of the added detail.
I got the best looking results using 4 sample box anti-aliasing, however that absolutely destroyed my framerate (it dropped from between 50/110 to around 7.) Edge-detect anti aliasing only makes it worse because of the way minecraft maps its textures, I haven't tried wide/narrow tent, might in the future.
For now I'll post a few screenshots I took, and if/when I discover more or better settings, I'll update this post.
PS: I'm not sure if the awful performance with high settings is my system, or java/notch's coding (it is after all forced, not native) so it might work just fine on other systems.
Without Anti-aliasing or anisotropic filtering
4 sample box type anti aliasing, no anisotropic filtering
4 sample box type anti aliasing, 16 sample anisotropic filtering
What happens when I try those last settings
Outside view, no filtering etc.
Outside view, 4 sample box type anti aliasing, 16 sample anisotropic filtering
Long story short (at least in my case) very much worth it for taking screenshots, making movies etc. but during regular gameplay, not so much.
System specs this was done with:
ATI mobility radeon HD 5470; 1 GIG VRAM
4 gigs of DDR3
AMD Athlon II P320 dual core (2.1 GHz)
This overrides Minecraft's GL texture settings, and allows your graphics card to filter them.
Also, I sent you a message.
