Game Unplayable

[Verhängnis]

"DirectX 10 ships with and is only available with Windows Vista and later; previous versions of Windows such as Windows XP are not able to officially run DirectX 10-exclusive applications. Rather, programs that are run on a Windows XP system with DirectX 10 simply resort to using the code from DirectX 9.0c, the latest version for Windows XP computers, although there are unofficial projects to port DirectX 10 to Windows XP."

According to Dxdiag I am running Direct X 10 but it seems it has no effect.

Btw Storebore is a Programmer, he's part of the Aviator Mod team and developes some of their most advanced code like their Air-to-air Rocket code in the 1956 Pack.

Hold on a sec

The Op's video card is a Dx9 card 9800GT how does a Dx9 card run under Dx10 ? It dont (properly)

Install Dx9 on your XP system

How do you expect to get correct CoD results with non standard Dx versions then come to the forums moaning your ass off its unplayable ......................... anyway...........


I showed how to use DX9 in CoD conf files as its set to DX10 default a few posts back.

What's all the other posts for ?????

Here it is again.


For DX9 Graphics cards you need to make some changes to the conf.ini's

conf.ini
Render=D3D10_0 changed to Render=D3D9


Copy this line

D3D9

Enter here as below.

C:\Program Files (x86)\Steam\SteamApps\common\il-2 sturmovik cliffs of dover

[BOB]
Render=D3D9

Also in

C:\Users\Steve\Documents\1C SoftClub\il-2 sturmovik cliffs of dover

[BOB]
EpilepsyFilter=0
Render=D3D9

[window]
DepthBits =24
StencilBits=8
DrawIfNotFocused=0
SaveAspect=0
Render=D3D9 < replace the DX10 line
width=1680
height=1050
ColourBits=32

If I'm not getting what's being asked here then my bad I suppose.

9800GT is a dx10 card, if I recall correctly is a dumped 8800GT.

Go here and click Specifications :

Verhängnis, I strongly recommend you upgrade to Windows 7, all your problems will disappear and the game is other in DX10.

You should put that card under DX10.

Thxz for the correction.

When I was testing a 9800GTX+ I got much better fps results with DX9 settings than DX10 in CoD

My point was to the OP that he should run CoD under XP with DX9

Your suggestion of getting Win 7 wont solve the poor performance of the GPU he has.

Indeed, they have a very low performance in DX10, we are talking about a dump of the first generation of DX10 cards.

The nVidia 9800GTX is a dumped 8800GTX Ultra, if I recall correctly, nVidia just did a core revision of the 8xxx series in the 9xxx series.

But if you tweak down those DX10 effects, like shadows and shaders, the game should run fine in non excessive high resolutions, in 1920x1200 you can have problems with 512mb of vram.

If the game runs better with that card in DX9 than in DX10 is how should be indeed, but is weird that in some cases is just the opposite with this game, I guess is a matter of drivers or hardware.

With my ATI 5870 the performance in DX9 is terrible while in DX10 is smooth and pretty.

You posted it while I was writting....

Thanks, your two posts explain a lot.

One more question: If the DX10 performance of a GPU is lousy (compared to its DX9 performance), is it worthwhile to have the game in Win7 OS, but making it run in DX9?

My experience doing this with other games show that the differences are minimal, depending of how the game behavior is in Windows 7 it runs better or worse.

But overall the differences are no appreciable.

The question is :

Now days, there any advantage sticking in Windows XP ?

That is good to know Alpha, did you benchmark the 9800GTX with WinXP+DX9 and Win7+DX10 ?
It would b bad news to all people who hope to upgrade to Win7 in order to solve the performance issues with WinXP.
I presume it is because the 9800GTX runs DX10 but NOT DX10.1
The older NVIDIA cards were running a DX10 version with shader model 4.0 and later generations were running DX10.1 with shader version 4.1

I do not know for sure what shader model CoD needs. According to an interview in pcgameshardware Oleg Maddox gave (11thMarch), CoD uses all DX10 and DX10.1 features.

If this is true then the GTX9800 can handle the shader model 4.0 but not the shader model 4.1 features CoD has in DX10 and this makes it slower in DX10 mode.


Hunter in Ubisoft posted a great link showing, among other information, which DX version and shader model NVIDIA cards have, worthwile having when going shopping for a second hand NV card:

DX10.1 is a small revision of shader model and a little Antialiasing optimization, if you have plugged a DX10 card instead a DX10.1 capable card those optimizations will not appears but you should can run the game anyways with DX10 only.

So if you are using a DX10 card instead a DX10.1 capable card the game should switch to shader model 4.0, instead 4.1, automatically.
