This is bug 4366511 - OGL: Multisampling does not support under
windows for fullscene antialiasing
Currently we are simulate this by 8 pass in the accumulation
buffer under OpenGL windows version so performance is slow.
However, this should works fine under D3D version if the driver
support multisampling.
Thanks.
