Hi all,

 

I have just been playing around with the SDK sample I and get a strange result (see below). Could someone please run the sample with the same options and tell me if this is a bug in the SDK sample or a local problem?

I am using the 2.01 SDK and a Radeon 5870 / Core i7.

Here is my output:
