i have ati radeon hd 4670. my fps is good. it weird but i play high settings. using realistic lights with customization mod. usually i got good fps and enviroment looks perfect.

but when i come near DAMN LIGHT SOURCE fps dramatically drops. unplayable. whatever light source it is, no matter. candles, lanterns, magic, shiny atronachs...

i ve tried everything : unistalling all mods, patches, reinstalling, set grapchisc low, high.. none of them worked.

my point is : HEEEEELLLPPP
