DX9 cards playing DX10 games - Page 2

post #11 of 21
yes, preferably to run any type of nextgen game, you will always need a fast video card, if the video card you have isnt 100% compatible, and by that I mean, has all of the feature set and is optimized to use those features.

For instance, we would all think that a GeForce 4 Ti 4600 would run doom 3 fine ? although it does not, it runs it terrably, much worse than what the performance should be. Although its not the latest card, it can contend with a Radeon 9700 in most DirectX 8.1 games, with the frames usually abit slower. But when it coems to Doom 3, a Radeon 9700 defeats the Ti 4600 totally becasue this card simply has not been optimized for the shadows, bump mapping, and lighting that the doom 3 engine uses, as well as the gigabyte textures that it uses. (im not going to go into gigabyte textures... its another story itself.)

I bought a X800 Vanilla board about 2 weeks ago, for the money, and considering the performance, its very good, and whats the point in upgrading to a 7800 GTX for $900 (AU) when the frames are roughly doubled, in the next gen games of Dx10, the frames between a X800 and 7800 GTX will drop ALOT, however you will see the 7800 GTX outperform the X800 still, and will do abit better than expected since it is DX 9.0+ compatible, so other features that arent implemented in games, already exist on the board.

However im just following the trends from previous DX technologies, its not yet known the full list of DX 10 features that will be availibe, and how it will all be packaged together. One thing for sure is, the same speed cards with Dx 10 will always outperform the same speed cards in Dx 9, if Dx 10 is used.

I think the whole DX 9.0+ means it's DX 9c, meaning it has SM3, some cards like ATI's X800 line only supports DX 9b meaning its missing SM3 and only has SM2.

Just a theory.

If it wasn't playable.. that would be like millions of people that may not buy another video game for a while crushing the video game industry.
Just another reason why the industry should go OpenGL... Then Microsoft couldn't control everything, or render things obsolete.

then we have Open GL 1.3 cards, and Open GL 2.0 cards and Open GL 2.X and X.X soon enough...

However ive still noticed some improvements that D3D has over Open GL, but personally, ive always liked the Open GL better especially when ive got any nVidia card in my system, seems to run much more stable, much much more when compared to D3D + ATi Card + ATi Drivers... one thing that isnt nice about ATi.

For example, Quake 4 and Doom 3 uses Open GL, and Unreal Engine 3 uses Direct 3D 9.0c, but it may possibly come out with Direct X 10 support, (if Dx10 exists by then) which will be around the end of 2006.

Not real bright of Microsoft to restrict these DX10 APIs to Vista Only! Only 10 games in development and although I can't find the link any longer, about a month ago Crytek released some information about a frame rate comparison between DX10 and the OpenGL APIs now controled by the Khronos Group (every company except M$)!

Can't remember the numbers, but OpenGL left DX10 in the dust on Crysis!

The only real advantages touted over DX9 is how the graphics card can now utilize system ram as well as it's own memory. Plus how the CPU will now off load all display work to the GPU in an attempt to better utilize the GPU clock cycles. Some other minor improvements and more defined shader specs. Also lightning FXs go to 128 bit.

So from my perspective M$ is shooting themselves in the foot and with OpenGL have the whole world against them in khronos Group brings Open Source Advanced technology into gaming for all platforms from the smallest to the largest. We've already seen the power of Open Source in Google and Firefox and OpenGL goes back as far as DX1 or futher!

http://www.khronos.org/news/press/Re...icly_released/

Khronos Group took over OpenGL APIs in July of this year and it's member and user list reads like a "Who's Who of Games and Graphics"! Amazing how all those members etc. dwarf a monopoly the size of Microsoft!

It will work. However you just wont get the graphical advantages with DX10

Exactly. And I would guess we would either get the same or better FPS due to the reduced graphical load.

Not sure about better FPS but very playable.

I was reading that, and Wondering why a 7800GTX 512mb was an uber high end card...
