I just got a new computer and upgraded my graphics card. What do I need to download and mess around with in the display settings (besides particles) to get maximize graphics out of this old game?

so far what I changed
- advanced lighting on
- shadows on
- shadow/actor clip plane full.

so far what i downloaded:
- classic spell particles
- character texture update


am i missing anything? any input is appreciated
