Ouch.

I'm waiting until R7xx when the power draw won't overwhelm my 400W PS and hoping there'll be an AGP version

LOL, no, I'll change the whole lot, hopefully 4-core, 4GB RAM and a lowest-priced enthusiast graphics card (hmm, do we need a new category, ultra enthusiast $550+?)

Games are definitely taking the piss out of my S939 3500+ 2GB DDR X800XT but I'm starting to think that this year's games (those to come) will make 8800GTX/2900XT cry for mercy. It pains me to say this, but I think SLI/CF may actually be essential to enjoy this year's coming games at a half-decent resolution with all the eye-candy and IQ.

They both start with an F and have a and r in the names, so you can extrapolate, that's my excuse anyway.

I shall go away and hide under a rock now after doffing my hat to him and buying an X1900XT that will last me till 2010 at least.

Whimper.

I think you have chosen a good time to upgrade to be honest. The price war between the two cpu manufacturers is keeping prices down in that area, even on newer stuff, DRAM prices are low for at least the next few months and nvidia and AMD/ATi will be moving to cooler, faster 65nm one would hope for the next round.

It's all sort of slotting into place. Good luck !

The snob in me finds the prospect of skipping dual-core, PCI Express and DDR2 very appealing

Does R600 support linear filtering for depth-map sampling in D3D and OpenGL (GL_LINEAR_MIPMAP_LINEAR)...?

I suspect it supports linear filtering, but of what use is mipmapping with a depth buffer? Surely not shadow mapping as there are entire shadowing techniques that exist entirely because filtering the depth buffer doesn't work

PCF is exposed under D3D, unsure about OpenGL.

Rys · 20-May-2007, 12:56

We see linear filtering is available for depth formats in R6x's OpenGL driver, but certain other formats are unsupported as yet (RGBE, FP10), at least given the way we're testing for support.

HD2900XT beats 8800GTX on Test Drive Unlimited , Company of Heroes and R6 Vegas

is it because these games make abusive use of shaders and consequently provides more efficiency from superscalar architecture ?

BRiT · 20-May-2007, 19:27

AFAIK, in R6V the HD 2900XT is not doing any AA while the 8800GTX is.

According to Anandtech's test, HD2900 beats 8800GTX in it when neither are using AA too on 1600x1200 and lower, at 1280x1024 it's actually within 0.2FPS from 8800Ultra

no-X · 20-May-2007, 19:54

yeah, R6V doesn't work correctly with AA+HDR+shadows... but there are another games or situations, where HD2900XT is a bit faster than GF8800GTX:

Call of Duty 2 (w/o AA/AF)
GTR2 (w/o AA/AF)
Oblivion (transparency AA+AF, 8.37.4.2 "EATM" driver)
Rainbow 6 Vegas (w/o AA/AF)
Splinter Cell 4 (w/o AA/AF)
Test Drive Unlimited (w AA/AF, w/o AA/AF)
X3: Reunion (w/o AA/AF)
Company of Heros (w AA/AF, w/o AA/AF, 8.38 driver)

but list of situations, where HD2900XT doesn't perform better than X1950XTX, isn't any shorter

CoH must be new development, because from 6 or so reviews that I've seen use it, GTX was faster than XT in all but one.

But also according to Anandtech, 2900 has rendering errors in the game so I am not sure why they even used it as a benchmark.

lol, remember the first review that hit the net (also the first review in your thread)

http://it-review.net/index.php?optio...1&limitstart=2

Geeforcer · 20-May-2007, 22:56

I just went through that list of reviews and looked up all the GTX and 2900 comparisons in CoH.

In CoH avg fps tests, 2900 wins over GTX/total tests:

It-review: 1/1
TweakTown: 0/3
VR-zone: 0/3
Inq: 3/12
Bjorn3D: 0/3 (did use FOC GTX)
ExtremeTech: 0/2
FiringSquad: 1/4
HardwareInfo: 0/6
BitTech: 0/6

For a total of 5/40, or 12.5 winning percentage.

How many of the sites that show the 2900 winning in CoH ran 8.361 instead of 8.37 or 8.38?

btw, in the inq review, the gtx scores more at 25x16 than at 19x12

Let me check.

Geeforcer · 20-May-2007, 23:24

It-review: 1/1 ???
TweakTown: 0/3 8.361
VR-zone: 0/3 8.374
Inq: 3/12 8.374, but yeah, WTH? The results seem all over the place. Excluded.
Bjorn3D: 0/3 (did use FOC GTX) 8.37
ExtremeTech: 0/2 ???
FiringSquad: 1/4 8.374
HardwareInfo: 0/6 ???
BitTech: 0/6 8.37

After excluding INQ results, 8.361 results, unknown driver results AND Bjorn3D's OCed GTX we are left with 1/13 or 7% winning percentage.

Did the french tester say there's no AA done by 2900XT? from my understanding, R6V uses MRT tech, it's not compatible with AA. 2900XT does support MRT+AA, if 2900XT can not do AA in R6V, then 8800 GTX can not AA too with HDR+Shadow on.

8.374 have two version, 8.3742 and 8.3743, I don't need to remind you the big performance difference between the two drvs.

Wrong. The 8800GTX does AA+HDR+Shadow on via way of a driver patch, similar to the ATI Chuck Patch. AMD/ATI have yet to produce such a patch for R6V.

Why to waste time with these old drivers? 8.38 driver is available and new results in CoH are very promising
