Hi Adrian, Does you machine support accumulation buffers? My guess is that the ATI simply doesn't support them so the example will fail. If there is a problem then I'd say its most likely the lack of auto detection of lack of support rather than any bug on the OSG side. I'm happy to leave fixing such stuff till after 2.2.
