Will Half Life 2 be Open GL or Direct3D or Both Please let it be Open GL and is it true Open GL is less affected by shaders
 
...

Wasnt it advertised how much better the 6800s would be with DX9.0c (back in early '04)...

bah
 
yeah 6800's series is better .. well they are the only cards out now that suppports directx 9.0c... but if ya meant just directx9.0 then yeah they perform way better than the last generation.. (fx 5xxx) and if ya meant they would perofrm better than ati cards... then it would probably be a tie for now because one is loosing to another all the time..
 
i think hes pissed becuase he has a FX5600 and a ti4600 in his systems.. the ti wont run dx9, and the FX will run it shittily.

not everyones got a 6800 or x800 guys :cool:

You got Doom3, we get HL2....get over it.

Since we haven't seen any HL2 benchmarks yet I'd wait until it's released before saying which card performs better. HL2 uses the Source Engine and in Source Engine tests in CS: Source, the 6800 series actually does pretty well against the X800 cards. The X800XT-PE will probably be fastest in HL2 based on it's great D3D and shader speed but the 6800U probably won't be far behind.

As for Doom3, ATi are looking pretty good in that too these days (after a metric assload of optimizations!) so NV cerainly doesn't 'pwn' ATi in D3. :D
 
i just hope steam someone patches in some form of HDR soon because this engine can really take advantage of it being less demanding from far cry's engine and still has great quality
 
im sure there wil be a lot of optimization for HL2 like there were for D3
 
Silly move by Valve really as the original ran in both D3D & OpenGl. Seeing the game advertised with an ATI voucher was probably the warning shot. Letting us have the choice of both API's would have been nice. That way we would be able to test our cards in both modes and see which one best suits out cards. Valve could have then helped both companies to sell their cards.

According to this web site http://www.xbitlabs.com/articles/video/display/cs-source.html the Nvidia's are really good if not better than ATI in these scores. The game will still be playable for pre X800 & 6800 series, but at lower settings.
 
The original included OpenGL because it was a heavily modified Quake engine. Any ID Software 3D engine has always used OpenGL. The addition of D3D was done by Valve. The only reason OpenGL was supported was because it was already built in.

They didn't feel the need to build in OpenGL compatibility with the new engine, and I don't blame them because the OpenGL 1.2 spec doesn't include all the nifty features that DX9 D3D can spit out.
 
not only htat, but half life SUCKED in D3D.. they gave you an option of a good engine or one that they slapped together

including both api's would mean that we wouldnt have hte game for another 2 years

HL1 sucked in D3D because it was a modified version of the Quake 1 engine, and im sure the OpenGL renderer was a litlte more matured than its bastard D3D step son.
 
Yeah damn valve for not making it run in both direct x and open gl, since so many other games like doom 3 give you that option.....oh wait.... :rolleyes:
 
You do realize ATI is paying for Half-Life II. So expect the game to be heavily optimized for Direct 3D. Don't expect Valve to make an OpenGL port until ATI has good OpenGL drivers. Same with PS 3.0 :p Gabe said it's possible but won't be implemented till later.

Don't worry about it. Nvidia is doing very well in Direct 3D front this time around. With each driver revision the gap is becoming smaller and smaller.

yet again he has a 5600U i dont think he is worried about the current gen, but rather the craptacular performance of his card in dx9 apps.

Yeah, and the shimmering is becoming worser and worser. :D

Let them solve this first, then look for performance gains. ;)

Woah in that case he should get a 9800 pro :p The FX series sucked donkey balls in Direct 9.0 shader intensive games.
 
I found this in a Q&A section where PCGamer asked the questions and some valve tech guy awnsered them.

"Q: Please share your thoughts on the latest generation of graphics technology -- NV40 and R420. Is one technology better than the other for Half-Life 2? By how much? Why?

A: The X800 is faster for Half-Life 2 by roughly 20 percent -- the 6800 supports standard full precision, but it's more optimal with partial precision. The X800 is designed for full precision from the ground up."

Which shows how much back ATI is giving Valve.

sorry, but "worser" is not a word

aside from that, wtf are you talking about? i have a 6800, i game a considerable amount, and i have never noticed "shimmering"(or any graphic anomaly, for that matter) the IQ is better than on my 9600pro, and its one hell of alot faster.

Bad_Karmal: im not so sure if they are claiming that anymore, that quote was from the launch of the 6800 and x800 series, at which time, the x800 did indeed have a very commanding lead.

Direct3D

OpenGL can do anything D3D can do, and D3D can do anything OpenGL can do graphically speaking

Crawling/aliased textures. Here, at Nvnews and Beyond3d are big topics about this (6800) issue.

well, all i can say to that is that i have zero problems with my GT, the IQ is as good or better than that of my 9600.

Unless you feel like being pedantic...

Anyway, just think about it like this: both run on the exact same physical hardware, how much difference can there be?

The main problem is that ATi's drivers (or any other IHV that is not NVIDIA, actually) are not that good with old style OGL code (display lists, glVertex()-calls etc). This code is very different from how the hardware operates (dates back to the days when transform and lighting were still done on the CPU), so it's the driver's job to translate and optimize the calls to something the hardware can do.
But more modern OGL code, which uses lots of extensions for vertexbuffers, shaders etc, runs quite well on ATi. The main reason is that such code relies more on the hardware itself, and less on the driver.

Direct3D has always been like this, so there have never been very large differences in driver performance. That is probably one of the reasons why Direct3D is more popular with game developers. It's one of the reasons why I prefer developing with Direct3D anyway.
