A BIG GRAPHICS PROBLEM- with pics to show

HI its me again.i still have a weird graphics probelm as i described in an erlier post. when the sliders in the display settings are all to the left it is blurry has it should be, so i then found out that to un blur the textures you move them to the right (am i correct?) but when i do this something strange happens.what i do is set most of the display settings to high and click OK, but when the main screen loads and i can see my aircraft the new top quality graphcis load and saty there for about 3 seconds before the old blurred graphics come back. i think it is like the computor knows what new graphic to load but is struglling to load themhere is a picture of what it looks like with all of the sliders turned up to high (to the right)
