rayg said:i was under the impression it was for the geforce 6800 series only
Bad_Boy said:doesnt the FP blending/filtering that the 6800 has improves on HDR as making it faster and better looking, theoretically i mean, as there isnt really any proof of this yet.
Lord Blackdrgaon said:you know what all the lights and stuff maybe the guy have god on his side![]()
But i will try the HDR when i get home on my 9800 pro.

tylerhskate said:would an x800pro be limited by my cpu if i were to run it at 1024x768 4xaa 8xaf? something like that...cause right now i cant even start farcry :O
Merlin45 said:HDR is better explained as better definition for colors near white and near black. by using a fp format for the pixel color, you can accurately do very large or small values that represent the ends of the color spectrum (avoid rounding of very small or very large numbers by using exponential notation) unfortunately you really need a fp framebuffer and fp blend to do this efficently, or else you have to do render to texture for each pass and do the blending in pixel shaders, which will slaughter performance.
but when you look at a game like HL2, which is already pushing tons of shaders, I think that the additional work of having to essentially render every scene twice to do the blend in pixel shaders, might be the straw (or log in this case) that breaks the camel's back, though it remains to be seen as we have yet to see HDR used beyond tech demos. If the x800 series has the raw PS power to do HDR in a game situation more power to them, though a fp framebuffer approach like the NV40 offers will be significantly faster.Brent_Justice said:thing is though is that the pixel shader performance on the x800 series is pretty fast, and on the r300 for that matter

creedAMD said:that's assuming way too much for a game that hasn't been released yet. Who's to say that HL2 doesn't bring the r420 and nv40 to it's knees without being able to even turn on AA/AF?
Only time will tell.

Vagrant Zero said:While it's a posibility, it's not very probable. HL2 has been in development for 5 years and it's going to show.
