I have a quadrofx 3800 graphics card. Is it possible to get dx11 working on it. My unity window says running dx11 on a graphics gpu , but the example scenes are not working.
No. The hardware does not support it.
Thanks- I am now trying a friends laptop with a gpu that should support dx11. The graphics card is an NVIDIA GeForce GT 555M and in the laptop nvidia control panel it states the current version of installed and supported directx is directx11. However the Unity windows says running dx11 on a dx10 gpu and tesselation is not working.
Bump.
Is the NVIDIA GeForce GT 555M supposed to be capable of dx11 in Unity? According to the following link dx11 is supported:
Yes, GeForce 555M should support DX11.
If you’re getting “DX11 on DX10 GPU” or something like that, then something is wrong. We don’t do anything special really: we try to create a DX11.0, 10.1, 10.0 device in this order. Whichever one is created is totally up to the driver.
However, if you’re getting a “DX11 on DX9 GPU”, then I’d check if you aren’t accidentally in a limited graphics emulation mode (Edit → Graphics Emulation). I think if your active platform is set to Android, then it goes into roughly DX9 (GLES 2.0) graphics emulation by default, since Android’s graphics capabilities are roughly that.

Thanks for your reply.
Still getting that message. I installed/ updated to the latest Nvidia drivers for the card. Is there something from Microsoft like a required DX11 runtime that I could be missing?
Just a wild shot but which OS do you use? DX11 requires windows 7 or newer.
Yeah I am running windows 7 64bit
Then no AFAIK, DX11 comes built in in win 7, i don’t think you need to install anything (except for the relevant drivers) to get it working.
Are you sure it’s using the nvidia GPU? I had an issue that may be the same since you mentioned it’s a laptop, the integrated intel GPU was set as the default, there’s no way to change it unity uses the default, but you can set it from the nvidia control panel, go to your nvidia control panel check that for graphics the nvidia device is set as default, if not , set it and then restart unity and see if it fixes it.
thanks ronan, that was exactly the issue!
Hehe np i had that bite me a while ago, also note that (i don’t know if it’s a nvidia bug, an IE bug or a web player bug) on my systems now that nvidia is set as default the webplayer “still” uses integrated, so if you see an asset you like that isn’t working, request a standalone player from the seller as that could be the issue.
yes i am getting DX11 on DX9 GPU error for android platform build…so whats the fix,and i am also using HDRP.
