Built a new system over the weekend:

i7 2600K
Radeon HD 6970
16 GB RAM 1600 mhz
120 GB Intel 510 SSD
2 x 2TB WD Caviar Black

Nothing is overclocked and everything is working and benchmarking perfectly, but the XBMC's GUI (not playback video) is slightly choppy compared to my older system. My older system was a Core 2 Quad Q6600 with a GeForce 8800 GT.

My only guess is that it has something to do with the 6970. If so is there anything I can do to resolve this? Can it be anything else?

Thanks!

I have similar jerky gui with ati HD5450. For me it seems linked to ddsfanart. With dds enabled scrolling through movie posters (for example) is not smooth. Disabling dds and deleting all .dds files from /thumbnails folder - all is good. Have you tried with dds disabled?

that is super htpc's spec, and you shouldn't have any problem playback any bd file.

please try the following guide-
if you haven't update the latest catalyst, you can update it from here- Graphics Drivers & Software. you need to adjust the hdtv resolution in the catalyst control center (Output to TV via HDMI port), and in catalyst control center, go to video settings and video playback, set it to enforce smooth video playback. do these in xbmc: system>settings>video>playback (select allow hardware acceleration (dxva2), adjust display refresh rate to match video and sync playback to display) and system>settings>system>video output (select full screen for display model and select same resolution as adjusted in catalyst). for audio in xbmc, do these: system>settings>system>audio output (follow the settings in this photos- pre-eden settings).

Thanks for the tips, but my problem is NOT video playback. Videos play super smooth and audio is perfect. My problem is XBMC's interface. For example, scrolling in: movies > library view > fanart

This sounds like a likely cause, although it doesn't make sense that my older, less powerful PC had no issues here.

How do I disable dds?

you need to edit your advancedsettings file. Delete the line that sets useddsfanart to TRUE.

I've no idea why this would cause the issues for GUI, nor can I find any posts discussing similar issue. But the problem definitely goes away for me without dds fanart. My other PC (Acer Revo with Nvidia Ion GFX) doesn't suffer the same problem. Using latest nightly and a varietly of skins (including standard confluence). Problem is not skin-specific

Verified that disabling dds and removing /Thumbnails fixes the choppiness. However, this isn't exactly a solution as it's a very significant feature that I would like to keep.

Any further help is appreciated.

As I say, not seen any other reports of this issue but good to see the "solution" verified by another user. I too would very much like to use .dds fanart as my media PC is fairly low power:

HP Proliant Microserver
AMD Athlon II Neo N36L Dual Core 1.3GHz
ATI HD5450 512MB
5 GB RAM
Windows 7 Ultimate x64
XBMC Nightly: 20110820-046AB03

Maybe create a trac ticket for this so the dev's can work on that.
