Okay, so on my 7300 equipped Macpro, precipitation looks strange - as if the point sprites had been scaled. There's no frame-to-frame coherency - some frames I see the expected rain/snow droplets, other frames I see enormous shaded spheres which I guess are the point sprite scaled up by a factor of a hundred or more. It's fine on my Radeon-equipped MacBook pro. The visual artefacts are accompanied by single-digit frame-rates, even quitting is tricky. If drag the precipitation slider back to zero, as soon as the rain stops, frame rates jump back to normal. I would post a screenshot, but it seems the Grab tool on Mac always grabs a 'correct' frame - I don't know how the tool works for GL contexts, but perhaps something funny happens which means it bypasses what is presumably another driver bug. Anyone else seeing this?
