Directxin crashes project

Whenever I go to unlock a Directxin TOP in 1 particular project Touch crashes. The project was saved with the TOP locked and now I can’t unlock it. I’ve also tried adding a new Directxin TOP but that crashes the project as well. I did a test with a couple of fresh projects and everything worked fine. It might have something to do with the fact that the project in question is using quite a bit of GPU ram and CPU ram (approx 3 and 4 gigs respectively )

I’ve attatched both the dmp file and the project file. also this in build 7780.

thanks

.dmp files says its crashing in the DX driver. We are unable to reproduce on our dual K5000 system with various GPU affinity settings. Any more details about the particular test case?
If you put a valid texture handle in the DirectX In TOP, does it still crash?

It did keep crashing from any valid handle.

Maybe because I rolled back Nvidia drivers (from 320.xxx to 307.xxx) the Directx driver installed is not compatible. Recently I noticed I have a problem with Maya not updating the screen properly also which never happened before.

But it is strange because it wouldn’t happen with fresh projects. I’ll look into further - maybe Nvidia has a new driver (that’s fixed the sync issue i mentioned).

thanks for looking into it

cheers
