7800gtx and hdr

[bunika]

I read on many places that 7800gtx can't do antialiasing and hdr together. But after playing Lost Coast demo I saw that actually that's not true. 16x anisotropic, 4x antialiasing and full hdr worked perfectly together. Any opinions about that?

Yeah, it's a bit of both.

GF7 cannot do OpenEXR+FSAA by default.

HL2 Loast Coast is not just plain OpenEXR HDR.

It's like some people naively saying that ATi couldn't do HDR during the GF6 series, they didn't understand the difference between HDR and OpenEXR implementation of HDR. It's all about the implementation/version of the effect and how AA is being applied (host based, reduced target based, etc).

We've discussed this a few times, another exception is AOE3 which can do HDR+AA, but once again it's a tweaked method of implementing HDR.

Yeah, wonder where we've discussed this before?

PS, you made me 'edit' my post when I was just changing an omitted owrd. DANG! :tongue:
