Hello
,
I'm also experiencing the same or a similar issue. I know this thread is older, but I thought it might contain some relevant information - that's why I didn't make a new thread.
I have a 27" main screen and a 40" secondary TV attached via HDMI. However: whenever I display video on the secondary screen in fullscreen mode - it starts to lag. The only exception is: if I turn off Aero Glass. Then suddenly there's no lag in fullscreen.
I'm on a core2 quad, 8gb ddr2 ram, nvidia gtx560. The problem didn't change when I used a different video output module. However - DirectX (DirectDraw) seems to deactivate that Aero Glass theme on its own. Also I used automatic video deinterlacing. It seems not to stutter at all, but of course it strips the whole desktop of the Aero Glass design. But otherwise the image and quality seems perfect.
Perhaps this could help to get an idea how to fix this issue? It'd be awesome to be able to leave the whole thing at Direct3D with all the visual style etc. and use fullscreen on my secondary screen.
Other than that - really great work! HDMI works - it even auto-switches to HDMI-Audio once I activate my TV. This is really awesome!
Thanks for the help in advance!
