If it helps, here's the specs for the machine causing the problem.
OS: Windows Vista Home Basic
Memory: 3GB
Processor: AMD Athlon 64 x2 5000+ Dual Core
Graphics Card: 2x Nvidia GeForce 8600GT running in SLI mode
It helps.  More detailed specs would help even more, both the community (to analyze) and you (to resolve).

v1.69? SoU & HotU installed? Overrides?  Disabled shiny water? Tried turning off threaded optimizations?  Tried rolling back driver?
