Unreal Tournament and 16MB G400

[Angst]

I just installed a 16MB OEM G400.
In UT I get flashing Horizontal Faint Lines.
Was wondering if this is an exclusive 16MB prob...and if others have had the same?.. Any Fixes?
I installed new drivers+bios.
Any help would be appreciated.

Thanx!!

not quite sure,but my 16 meg gives me perfect results 1024x768,32bit.
