# Optimizing &kdetv; for your needs (Performance/Quality)

- Performance

  You can get best performance (least CPU usage) by using a &xvideo; or &video4linux; plugin-driven device and configuring the plugin to use overlay. You will not be able to use deinterlacing or overscan in these modes.

- Picture Quality

  For the best picture quality, use a &video4linux; or &video4linux2; plugin-driven device and configure the plugin to use the &xvideo; display method and full frame rate. Use the &tomsmocomp; deinterlacer and adjust its configuration options to suit your CPU speed. If the picture is jumpy (easy to see on horizontal scroll texts) your CPU is not fast enough, so video frames are dropped.

- Quality / Performance Tradeoff

  For a good tradeoff, use a &video4linux; or &video4linux2; plugin-driven device and configure the plugin to use the &xvideo; display method and half frame rate. Use the &greedy2frame; deinterlacer. If the picture is jumpy (easy to see on horizontal scroll texts) your CPU is not fast enough so video frames are dropped. Alternatively, you can use a &xvideo; plugin-driven device if your hardware combination is capable of deinterlacing (you need to check it for yourself on horizontal scroll texts).
