All I want this thing for is XBMC.

When I use XBMC there is a very noticeable difference was the interaction. Very sluggish compared to 1st gen. Any ideas what is causing this?

By the way, this was the first time out of the box ATV too. Could it be a bad install? Thoughts?

The GPU in ATV2 is slower than that of ATV1. We will obviously continue to optimize but a lighter skin (like SLiK) might help out quite a bit.

Ya but the processor is much better then ATV2 vs ATV1.. that should ofset the difference...

Anyone try a reduced texture skin like the ones made for the original xbox?

What about the GUI fixes you did last summer ?
The normal XBMC log IS NOT a debug log, to enable debug logging you must toggle it on under XBMC Settings - System or in advancedsettings.xml. Use XBMC Debug Log Addon to retrieve it.

They might help if the skin utilize it properly but it also depends quite a bit on the GPU, the one in the beagle it didn't help as much as wanted (50% increase on average in confluence, much higher variance in fps though). When we have time we will most likely try this out. The fixes can't be merged in to mainline atm since it trades GPU for CPU (lots of extra processing to determine what to render) which is obviously far from optimal on the majority of HTPCs atm (ION etc). When we move to a more event driven processing and rendering it can be merged in without any downside on any platform.

What about enabling DDS fanart? Would that help with the ATV2, as it does with my ION setup?

Nope, it is directx specific (the codec inside is ok on opengl also), not supported in gles. There are equivalent technologies for gles, this is something which we for sure would like to add for fanart and such. It does not help anything with rendering speed (in theory its worse) but it will decrease load time significantly

What about scaling everything down (textures specifically)...

I'm going to suggest SFTP which is how you would do it on an idevice. Not sure where themes are stored tho.

SFTP is indeed the right tool for connecting to iOS-device (in my case a ATV2).
Username: root
Password: alpine
The skin directory for me was:
/Applications/XBMC.frappliance/XBMCData/Addons/skin.confluence/

Update:
Damn, Davilla in on fire! https://github.com/xbmc/atv2/commits/atv2
- Webserver enabled.
- Moved to non-pre Dharma.
- Etc.
