I dont think your PC is good enough to run the game at the settings you have it at.

Make sure to set Enhanced Effects to normal
That's a very weak cpu Emmanuel, which might be the cause of some of your problems - graphical settings like you mentioned are affected by gpu performance, unlike showing many players at once which is more cpu-bound.
*edit* try setting enhanced effects to 'normal' down from 'high'
