I get the same thing with an nVidia Quadro FX 380 with 256MB video memory on 
Windows 7. When I switch to OpenGL on the same system it doesn't happen. That 
doesn't mean its an ANGLE bug of course.

The problem seems to get worse the larger the window is.

I ran it with the debug D3D runtime and it didn't catch any D3D errors.

"The problem seems to get worse the larger the window is."

I was getting some severe stuttering as well in other applications with my 
GeForce 8500 GT 256 MB, especially at higher resolution. It was a VRAM usage 
issue which got fixed in ANGLE r618.

Could anyone else confirm that this revision fixes the Halo demo issue? Thanks.

It (still) runs fine with the latest ANGLE revision.
