My system:
AMD Athlon 64 X2 4200
ATI 4350
1GB RAM
What can I do to improve 1080p playback? Right now it's slightly jerky.
Will a better graphics card help (eg. ATI 46XX)? From what I understand that should not help since it's basically only better in 3D performance.
I also set skiploopfilter to 48 in advancedsettings.xml which made no difference for me.
Outside of XBMC I use CoreAVC codec which plays 1080p perfectly smooth.

Given that I'm running XBMC on Windows XP, will a different graphics card help?
I'm going to give DSPlayer a try, but it looks like it will play like an external player instead of fully integrated into XBMC, correct?

While it isn't dvdplayer, dsplayer is designed to play exactly like any other fully integrated portion of xbmc. This means the overlay will be the same. Controls via keyboard and remote will be the same. For all intents and purposes, dsplayer is just another part of xbmc that just happens to use dxva for HD decoding rather than ffmpeg.

Does anyone know if switching to an Nvidia card will improve my 1080p playback performance? I'm running Windows XP.
I couldn't get the dsplayer version to work (it was also slightly unstable, with jerky UI, video freezes, etc).
I don't think adding more memory will help. If my system is indeed swapping during playback it would look a lot worse than just a few dropped frames here and there.

I was under the impression from reading other threads, and from other people's opinions that it was the CPU and not the GPU on the video card that is doing the work? Is this wrong?
That being said, I have a P4 w/1MB RAM and I'm going to be swapping up to a Core2Duo shortly, so I can report my findings, as I also have slightly jerky performance on MKV files.

It depends on the external player. Some such as mpc-hc, allow for GPU decoding, but don't guarantee it or anything. Others don't. You'd be better off reading about the various players.
