S!

7950HD seems to be a strong performer in it's price class really Times will get really interesting with nVidia's offering coming out at some point.

Thank you.

We knew from our Radeon HD 7970 launch coverage that this architecture does not handle DirectX 9-based apps particularly well. Whether that’s an inherent compromise or a lack of driver maturity will become more evident over time.

What is immediately apparent, though, is that switching into DirectX 11 mode, which hammers every other architecture, turns out to be a simple movement sideways for the Radeon HD 7970 and 7950. In fact, at 2560x1600, both boards perform better using DirectX 11.

Hm... Anyone knows if CloD is more DX9 or DX10 application (or both depending on conf.ini setting)?

Does changing Render=D3D10_0 to D3D10_1 or D3D11 or D3D11-0 in conf.ini change performance?

Hi there Ataros, this is from a post Luthier did on performance.



E. NOTE: DirectX 9 offers slower performance and lower graphic fidelity. If your system meets Recommended system requirements, upgrading to a DX10-capable operating system will offer better performance boost in Cliffs of Dover than perhaps any hardware upgrade.

Hi, MajorBoris. Thanks for info.

Then we are lucky we have a DX10 engine at least unlike some other games.

Hi!

What does D3D10_0 and D3D10_1 means? Off and on? Thanks. I did try D3D11_0 but it had a performance hit for me. Now I use D3D10_0.

I think these are different versions of DX10 or different ways the game uses DX10.

S!

I use the setting DirectX 10_0 meaning it uses DirectX 10.0. Not sure if changing to 10_1 does anything. But that we know that 11_0 does not fully work yet. And as of AMD not working in DX 9..I doubt it. Played older games and they run just fine.

I'm trying to figure out why the 3gig card Flanker is using does not take the FPS hit on particles, ie, dust, gun firing that the 580GTX 3 gig experiences. Any ideas?

[Ataros]

It has different architecture and is generally faster according to many other tests. Thus it may be faster in CloD in complex scenes where FPS is minimal.

But I am not sure it does not take the FPS hit on particles. To prove it you have to run the same track under the same conditions (CPU speed & cache size, memory, game and driver settings, software running, etc., etc.)
