Very interesting article. Puts into question just how much of HL2 is DX9 really. Seems like not much.
What really surprised me though is the HDR. It seemed like it existed on DX8 cards!
Visually, except from the Radeon vs geForce brightness change, the game seems to use HDR on DX7 without a single change in quality. It makes me wonder just how hyped was this feature and how recent is it. Maybe those were crappy examples, but I thought HDR was all about powerful lighting effects against things that block light sources. Then again I still wonder if the expression High Dynamic Range really means special ligthing effects.
I liked some of the bump mapping used in HL2 as well, but again, looking at those wall shots, I can't help but remember modern games' graphics and feel like it's very much like them. That's where I was coming from when I said DOOM III currently holds better technological advancements visually. If you can feel CG quality playing HL2, I will retract my statement, gladly.
Personally though, I can't help but feel like there's something wrong between DX8 and 9 shots of wall textures. It just doesn't make sense one detailed sharp texture later is supposed to be a less detailed one but more "bumpy" (by a little). Ask yourself this, if you first played in DX9 and saw the wall example, then switched to DX8, would you feel like it's gotten worse or more detailed?
Overall this is one of the most interesting articles I've seen in a while, simply because for once, we're shown in depth examples of DirectX version differences! Finally DX8 shows itself as a serious evolution over DX7. And DX9 now reveals to us the truth, that it simply ISN'T being used as much as we thought lately, nor is it displaying anything amazing so far. We need a more serious programming to see that, and I feel if it's not now, it won't be for a while too. (yet DX9 was out 2 years ago!)
As for the geForce FX forced at DX8.1, it's as if we're told it never supported DX9. Doesn't anyone find that just a tad bit misleading? I also don't like the fact Valve FORCES DX9 card owners (the GF FX ones) to run the game at DX8.1, even if DX9 would slow it down, they still paid for a DX9 card. Kinda disappointing honestly. Even though I can see their intentions and they're not really wrong in nature.
BTW it seemed that the rippled pink rectangle in the well pictures we talked about days ago where I said the 9800XT seemed to have less IQ than the FX, was maybe a true effect. That crunched pink rectangle in the middle was actually supposed to look rippled from what was in fact water over it!
Bah I've talked too much. :tongue:
