sqrt[-1], late yesterday I noticed I have a bug in the framework that doesn't reenable anisotropic when the device is reset, so that causes it to become a bit blurry instead. I haven't had time to fix it yet, but I'll do that tonight.

i don't see how this is more "effective"

I found it more effective to just push FSAA to max(8xS) on my GF6800ULTRA.

On my Geforce6 I found that the aliasing artifacts went away if I resized the screen by one pixel.

I don't think this is any "magic" as while the specular is still there, it is less defined. My guess is that the normalmap is not using the highest mip levels after a resize. (tested at different starting resolutions and it still happens)

Yeah, but I haven't seen any of those in action, so I don't know how good they are. I'd love to have one of those, but I bet they cost an arm and a leg.

Sounds kinda cool. Aren't there any HDR monitors which could make use of it?

With RGB10A2 one would still have to do some tonemapping, but in that case we're probably talking about relatively small ranges, like 0-4, so you could probably get good results with a simpler tonemap operator such as just multiply it up/down to desired range.
The X1K can display FP16 surfaces, so technically they could be used in the framebuffer. The display engine can also do the tonemapping directly. However, DirectX only supports at most 32bit formats to be displayable. It's possible that it will be exposed in an OpenGL extension at some point though.

I wondering if you use this format for HDR rendering and also use it as backbuffer , one wouldn't need to do tonemapping?

btw about tonemapping i've heard that the x1x00 video engine could be used in 3dgames to do tonemapping with a trick.
