Here is my experience with performance issues:
- Nforce 8200 based system
- Athlon X2 5050e @ 2.6 GHz
- 1 GB RAM DDR800
- XBMC 8.10 on WinXP SP2, latest stable Nvidia drivers
Some samples at 1080p. Nearly no frames dropped. OSD states avg. CPU usage between 50-80%.
When run windowed I can see in the task manager that both cores are used equally more or less.
- XBMC 8.10 on Ubuntu 8.10, Nvidia driver 177.x and 180.x
Same samples at 1080p. Much more frames dropped. OSD states each core separately. One core is used upto 100% while the other is idling at 50%.
Seems to me an issue in libavcodec and threading on multicore systems.
Any idea? Known problem?
