Re: vdpau slowness with 260.19.06
When you see the slow performance, are your machines running out of RAM and swapping? There is a bug in all current 260.19.* releases that causes VDPAU to consume an extremely large amount of system memory at startup (e.g. 1GB). We've fixed this, but the driver with the fix has not yet been released. This could cause performance issues or outright failures on systems without much free RAM. Still, your issue might be completely unrelated.
