  • CoH & Vista 32/64 & DX9/10 Comparison


    I just finished doing some comparison testing I thought I would share. Nothing earth-shattering here--the results are about what you would expect. I was hoping with 4GB of RAM that Vista 64 would see some performance gains, but that didn't happen. There is essentially no difference in performance of CoH under Vista 32-bit vs 64-bit and DX10 is an equally crappy performer under both. So much so that it seems pointless to even bother running in DX10 mode. Whatever graphics fidelity you hope to gain is more than offset by the fact that you will have to turn down most of the settings in order to maintain a decent framerate.

    The Rig
    Intel Core 2 Duo 6700
    4GB RAM
    nVidia 680i chipset
    nVidia 8800GTX GPU

    The Config
    CoH was run with the following settings under both DX9 and DX10 modes:
    • Model Quality: High
    • Anti-Aliasing: 8X CSAA
    • Texture Detail: High
    • Shadows: Medium
    • Reflections: Low
    • Post Processing: On
    • Building Detail: High
    • Physics: High
    • Tree Quality: Medium
    • Terrain Detail: High
    • Effects Fidelity: Ultra
    • Effects Density: Ultra
    • Rain Detail: High
    • Object Scarring: On
    • Model Detail Slider: Max


    The Results
    .........................DirectX 9
    ..............Vista 32-bit...Vista 64-bit
    Avg FPS...........58.0............57.9
    Max FPS...........61.0............62.1
    Min FPS............32.0............27.6

    ..........................DirectX 10
    ...............Vista 32-bit...Vista 64-bit
    Avg FPS...........34.8............32.4
    Max FPS...........60.0............60.1
    Min FPS.............4.7............. 2.8

    Note: The Max FPS is the same for all tests indicating that this is likely CPU limited rather than GPU limited.

    Nice Firestarter. Running DX10, even with a high end rig, is a big strain. I've got the same build. I keep it at DX9 with all the settings maxed for that DXversion.

      it doesnt even look all that much better. dx9 on max settings is far superior due to the massive fps difference

        So then we are agreed, DX10 is just about useless at the moment?

          Not useless. DX10 does look better if you are able to crank all the graphical goodness up. But with CoH that seems impractical at the resolution I'm running without a second 8800 to push the FPS up. I supposed I could reduce my resolution to something other than the native 1920x1200 and then max the graphical settings, but that too is a trade off.

            On the other hand, since I do have some framerate overhead in DX9 I just upped my Shadows to High and my Antialiasing to 16xQ CSAA and I still have the following under Vista 32:

            Avg FPS...........50.0
            Max FPS...........60.1
            Min FPS............22.4
