I recently build myself an HTPC:
Athlon 2.6GHz Dual Core
XFX 8200 GeForce Motherboard
2GB RAM
1TB HDD
I'm running XBMC XVN 22278 (downgraded from 22294 because of passthrough audio issues) on Ubuntu 9.04. I'm using the stable release of the 185 NVidia driver. I use this machine on a 32" Samsung LCD TV. While it only goes up to 720p, which is perfectly fine for me, some of my videos can only be found in 1080p resolution. So, while I don't feel the need to be able to play 1080p... I certainly should be able to with what I've built, yes?
I've never been able to get 1080p playback working well, even when I was using other videocards. But this IGP is the best I've had yet, and I have VDPAU turned on. But I can only average out to 17fps.
For this test I used the killa video - http://pastebin.com/f44f72ae0
I've gone through everything I can think of. I've turned off interface enhancements in Ubuntu. I've tried with vsync on and off, it seems to make no difference. I run XBMC at 1360x768, same as my Ubuntu desktop, which I believe is the native resolution for my TV. (It looks so much crisper this resolution than normal 720p.)
One thing I notice is weird is that the three options I have to run at 768, the three differnt hertz refresh rates (that's what they are, correct?), 50, 51, and 70-something. I have to use the 74-ish or whatever, because if I turn it down to the 50s, the resolution inside XBMC blows up HUGE, but just gets cropped offscreen. Meanwhile, my TV reports that it's running at 60Hz.
I've checked my BIOS, I have my IGP RAM set at 512. This RAM is a bit cheap, I have one stick of I think DDR2 800 2GB... maybe the RAM is too slow? I dunno, I'm getting to the point where I'm debating trying to overclock the GPU... which would go against the reason I built this machine, to run cool.
