Parhelia "gave" us DM and ATI has had GI since 9700P.  NV did give us FP blending first.  I'm not sure about soft shadows.  I believe NV helped SSs with PCF in terms of performance, but I think SSs are still available on R300-R520, in which case PCF/Fetch4 isn't required.
	
	
		
		
			I was saying we need to reward nVidia for bringing features like this to market, because without that, no games.
		
		
	 
Er, games still, tho maybe not as pretty.
Big roll eyes to your ad-hom of linkgoron, especially considering the shaky arguments (strawmen and contradictions) in your preceding and subsequent posts.
Anyway, yeah, HDR is currently niche (HDR+AA, moreso), but there are more than two games that pimp it.  HW.fr lists five "HDR" games in 
their X1900XT(X) review (words French, graphs universal--look for the inevitable English translation at BeHardware.com): HL2 (& CSS & DoD), Far Cry, SS2, SC:CT, and AoE3.  ATI can apply AA to HDR in four of those, NV in two.  In the two cases where we can compare HDR+AA,  ATI & NV are pretty even in HL2 (both use the same methods), and ATI whups NV in AoE3 (ATI uses FX10 + MSAA, NV uses FP16 + SSAA).  FC and SS2 show an almost halving of framerate when adding MSAA to FP16 HDR at 16x12 and 19x12.  (This could be b/c the cards hit a bandwidth wall.  Still, dialing down the res should net playable framerates at 10x7 and maybe 12x10.  The question becomes, is HDR nice enough to warrant dropping screen res that far?)  SC:CT doesn't allow for AA with HDR, but I'm not sure if there's a technical reason for it (also, it renders HDR with FX16 for ATI and FP16 for NV).  In AoE3, adding AA to HDR costs ATI 10% (FX10 + MSAA), but it costs NV almost half their framerate (FP16 + SSAA are fillrate and bandwidth vampires).
So HDR + AA doesn't look that out there, especially when using ATI's new (and so far exclusive) FX10 mode.  Dunno how the lower precision affects the "HD" part of HDR, though apparently you can achieve FP16-equivalent range with lower-precision formats and some creativity (albeit with some limits--see nAo's and DeanoC's posts in B3D's console section).  We'll see how HDR is implemented on PS3, but you have to think something along the lines of FX10 or HL2's "dynamic range" solution will be preferable to bandwidth-sapping, ROP-consuming FP16 blending on a part with a 128-bit memory bus.
I'd like to see an IQ summary and comparison in these HDR titles, and five seem like enough for a decent article.  I'd be interested in comparison shots w and wo HDR and--where applicable--b/w ATI and NV's different precisions and AA modes.  SC:CT showed a noticable difference b/w "HDR" on ATI and NV, but I don't think SS2 or AoE3 showed the same.
Ugh, it'd also be nice to have a mod trim the absurd amount of flaming in this thread, namely the whole BouZouki cluster@#$%.  While I didn't really appreciate the tone of B's first post, it didn't seem that different from Rollo's second--which got a similarly virulent response.  Wonder why....
Anyway, I'm a fan of <a target=_blank class=ftalternatingbarlinklarge href="http://www.hardware.fr/articles/605-17/radeon-x1900-xtx-x1900-xt-x1900-
<b">rossfire-test.html">HW.fr's performance summary</a> because it's nice to occasionally see the forest rather than only trees.  It's helpful for those looking to game at 16x12 or 19x12, anyway.  I suppose the next step would be to find a way to dynamically normalize those scores relative to price--dynamic in that as prices change, so does price/performance, which is probably a simpler and therefore stronger purchase determinant than minimum desired performance.  IOW, ppl are probably more likely to seek the best bang for their buck rather than explicitly check which card offers the framerates they want in the games they'll play, which is more SLI/XFire money-is-no-object territory (it's equally valid, just probably applicable to fewer people).
Edit: Holy @#$%, Rollo, if you were a mod you'd have to strike that entire reply of yours to munky.  Along with most of BouZuoki's and some of Ronin's posts.  You hear that, omnipresent and overworked AT mod?  Get crackin'!  And post something funny while you're at it.
