Re: GT520 VDPAU deinterlacing options
I'm not so sure, though. The 520 is more or less identical to the GT218 aka "Ion2", and I know first-hand that the Ion2 I have here gives silky-smooth Advanced/2X playback. But without "vdpauhqscaling" -- can't handle both at the same time.
For a discrete card, the 430 still looks the current best all round performer. Now we just need a fanless 5xx version of it to appear.
