Does anyone know why the game won't get past the loading when I enable DX11 beta in the advanced video options? I know the gts 250 only supports dx10 but I thought they were backwards compatible so I was confused when the game didn't start. Any ideas?

    There is your answer the gts 250 is a base tier gpu that was released before DX11 was made avaliable to ATI and NVIDIA. To run DX11 you need a minimum card of a Geforce GTS 450.

    100% wrong.

    While the GTS250 is not on a hardware DX11 feature lvl (it is on a DX10 hw f lvl) it does support and works fine under DX11 (able to use some DX11 advantages over DX10 -or DX9 in case of STO- but of course no DX11 hardware features like tessellation and such).

    You were right, DX11 is backwards compatible.
    Check your driver version, which are u using?

    Which OS are you using?

    Windows XP means no stinkin´ Direct X 10 a, b, c or 11! :p

    And trying to use a Dx10 card with Dx11 features is usually NOT gona work. No matter what anybody claims.

    Thank you everyone for you responses! I went back to an earlier NVIDIA Driver and the game now loads in DX11. I know that I will not get all of the advanced features, but I switched Rendering engines to gain a FPS boost , and I must say my boost is quite large! I am now able to run the game at max settings and get 60fps or higher almost everywhere with only one GTS 250 and I have another one on the way from ebay to go SLI. My monitor is only 1440x900 so I don't really need a high end card and I didn't feel like upgrading right now when I know Geforce 780...760 are on their way in a few months. Anyway thanks for all of your replies!

    Can you tell us which versions of the nVidia driver you were using? Which one was broken, and which one did you go back to where it worked?

    Sry but you don't know what ur talking about. Sure DX11 hardware features are not available to DX10 hardware but still DX11 is useable on DX10 hardware, some ppl don't seem to get that.

    On my system with a GTS250 STO works in DX11 mode but aside from the visual issues/ bugs with Cryptics reder port it's performance is far worse than with the DX9 mode.

    Latest Nvidia beta driver (295.51)

    btw, can you guys implement FXAA into STO? It would be nice way working around whatever stuff you have had problems with gettin AA to work with all effects in your DX11 renderer and also neat for a lot of systems which can't really use traditional Antialiasing for performance reasons and a ncie addition for ppl who could combine the two methods.

    And you don´t seem to get the difference between true hardware acceleration and software emulation that Dx10 hardware "running" Dx11 offloads to the CPU and the hopefully not too buggy drivers.

    You got that mixed up a bit there also you totally misread my post. DX11 has a fallback, it's not software emulation of any hardware features, get ur fact's straight.
    Direct3D 11 runs on Windows Vista and Windows 7. It will run on future Windows operating systems as well. Parts of the new API such as multi-threaded resource handling can be supported on Direct3D 9/10/10.1-class hardware. Hardware tessellation and Shader Model 5.0 require Direct3D 11 supporting hardware.

    Get yours straight too (from your own post):

    Hardware tessellation and Shader Model 5.0 require
    Direct3D 11 supporting hardware.
    ^^^
    What this means (if you do not have a DX11 hardware native card) is:

    -Some features may disoplay stragely, OR the software in question may run everything in a DX10 (or even DX9) compatible mode - which will lessen overall performance (or cause other issues) you would not see with a true DX11 hardware supported card. Also, be aware that even the earlier wikipedia article you quoted states that the API can support DX11 feature in earlier cards it's up to the programmers of the app making use of that API to actually do that for non- DX11 hardware cards - and they may or may not do so; as it requires extra coding and testing time.

    .. muss man sich eben informieren. Is scho recht.

    BTW we´re still calling each other names about two different things.
    You´re talking about the API and it´s parallelization features (which are still most effective on DX11 hardware only BTW) and me about the actual DX11 GFX features.
    But that discussion would needlessly derail the thread even further.

    You too misread my post. I didn't state hardware DX11 features would be available to DX10 hardware, in fact I explicitly pointed out limitations but also how DX10 hardware can still make use of some advantages the DX11 API has to offer (also quoted, but you chose to leave that out).

    Vielleicht auch mal daran halten.

    No in fact you misread my posts but kept insisting to know it all better without checking again (what I wrote and what the facts are), fine with me but you added nothing of value to this thread and only tried to be a smart *** and derailed the thread.
