[QUOTE="globaldonkey, post: 420973, member: 49844"] Thanks Owlsroost. You probably saved me hours of failed attempts to get this working. You were right, as soon as you drop back to PIP on a large display, the GPU went through the roof. Went from about 50% to 80% when running in a window, and the de-interlacing started to miss a fair bit too. Of course I couldn't see MP running in full screen and watch Catalyst at the same time, but safe to assume it was maxing out. I don't know why I didn't think of that..... Found this on AnandTech about the 4350 and 4550. Looks like the 4350 might struggle with this scenario too. [I]AMD states that while both the 4550 and 4350 support full hardware Blu-ray decode acceleration, the 4350 may not be able to fully accelerate a high bitrate 2nd stream for picture in picture scenarios.
