I've just built up a new HTPC with a Geforce 210 driving a Samsung TV at 1920x1080. Using MediaPortal I only get 37FPS instead of the full 50FPS which I should get with interlaced 1080i (DVB-T TV1,2,3) Using either PowerDVD or the built-in Win7 Codec. Dropping frames like crazy.
CPU is at about 20% on a core2 4300 1.8ghz So it looks like HW acceleration is ok for the decoder but is there an issue with HW acceleration for de-interlace??
I've got 2 other HTPCs with no issue at all with 1080i content, both using PDVD code
One with 8600GT running Vista (EVR)
One with 9400GT running XP (VMR9)
Another funny thing when I make MedaPortal a small window instead of full screen the frame rate increases.
Is the Gefore 210 worse than the 8600 or 9400!? Is this a windows 7 issue? Any ideas anyone?
