Slow Texture Update

[Guest]

Simmers,Running win me, 512 dd,r gf4 ti4200, athlon 1.4, asus m/b and S/B Live Now i like to run Proflight and the PSS A/Bus but i have noticed the V/C cockpit keeps flashing white when changing to it and the outside A/C textures are all gray for about two three seconds plus when changing veiw my sound stutttttters badly. Any ideas tried all setting in FS and AGP on/off.Asked PSS but they inform me that the flashing white problem is the reflection and shadows made by FS and you cannot do anything about it, is there a file i can edit them out?Thanks RB211
