Directx

[jbohan]

I have installed DirectX SDK on my computer. However, every time I open Revit Architecture 2013 I get a message "The DirectX Software Rasterizer cannot be initialized. Please install DirectX SDK to run test properly." The program seems to run properly however.??

Hi,

This sound like it might be a problem with you graphics card and/or graphics driver.

What type of graphics card do you have and what version of the graphics driver are you using?

What OS are you using?

Card: GeForce GTX 260M

Driver: NVIDIA ver. 8.15.11.8631

os: Windows 7

Hi,

One thing that I do see is that your driver is a bit old, that might be the problem.

Let's start by checking if turning off Hardware Acceleration get's rid of the error:

- Open up the Options dialog

- Select 'Graphics'

- Uncheck 'Use Hardware Acceleraton....."

- Click 'OK'

- Close Revit

-Start Revit again

Did you get the error? If not - I would guess that this is an issue with the driver. Check your system vendors site and/or Nvidia.com for updated driver.

Once installed, turn on HA again and the error will most likely not appear.

Note however that there is currently a know issue with semi-transparent materials with some Nvidia graphics card that you might run in to. We are working with NV on this issue and there will be a new driver posted (I have no ETA on the new driver)....

If you do see an issue with this - turn off HA for now until there is a new driver that fixes this issue is posted.

If you still get the error after tuning off HA and/or the new driver does not help , could you post a journal file here? (or send it to me)

Just start Revit, open a new project and close Revit again.

Grab the last Journal.####.txt (where #### is a sequential number) in:

Still getting the message. I can't turn on the 3D accelerator. I get the message that I am in software emulation mode and that my video card and driver are not compatible with the program. However I am able to work in Revit 2013. Attached is the journal file

Hi,

Could you try something else?

- Browse to: http://www.microsoft.com/en-us/download/details.aspx?id=35

- Download and run dxwebsetup.exe

Start Revit and try to activate HA again.

If you don't get the message,

- could you please post your last Journal-file here as well?

For other reading this post: Please do not install the DirectX SDK - it will not help and it will only install a lot of unnecessary files on your system.

The problem of the error message has been solved. However now ray tracing doesn't work well with or without HA.

Could you please attach the latest Journal ?

I have 6 GB of RAM. This doesn't appear to be enough for Revit Architecture 2013. This is especially true when I try to use Ray Tracing. I can really only do quite simple projects. Is there a work around?
