DoD HDR will run on all DX9 cards!

HDR & You...

"...On NVIDIA cards, it stores these values as 16-bit floating point data (what is known as a "linear color space," as opposed to separate RGB values), and on ATI cards stores it as a 4.12 integer value (again a linear space). The advantages of this technique are many. All DirectX9 hardware is supported, and because it does not require that much extra texture memory the performance hit is small even on an ATI 9600. Fog effects work, and so does FSAA..."

"According to Gabe Newell, cards like the 9800 [...] and above are much less affected by the addition of HDR." Because of the number of pipes.


"HDR can be turned on, partially on (bloom only) or off by simply going to the Video tab on the Options menu."

http://arstechnica.com/articles/culture/lostcoast.ars/4

All DX9/FP16 cards can run HDR.

A sum up of what settings your computer can run at:

* In my opinion, your framerate should be around the same as the framerate you get in HL2DM (HDR OFF)
* But, if you run DoD:S with HDR, I estimate about a 12FPS drop - That's if you have 1GB of RAM and an ATi 9800Pro or better video card.


taht's form smash off the steam powered forums, a valve person thingy :P

old news actually, jp already posted twice about HDR availability.

If you check his post, Source engine has 2 HDR modes, Low quality and high quality.

Low quality has only blooming effects, a similar effect can be seen on the Nature game test of 3DMark2003.

Low quality HDR is available on any DX9 capable card.

High quality (Full HDR) is only available for cards that support SM3.0, which currently only the 6600, 6800 and 7800 range of cards from Nvidia. The next range of ATI cards should support full HDR too, X1600, X1800 i think, maybe others i can't think of.

actually, HDR high runs on SM2.0 according to smash as long as its a DX9 card, the lower cards (dx8 or SM under 2) will run on teh lower setting, the 'bloom'

so nar ners :P
