Why does DW make my video card squeal?

[XanderF]

Possibly a workable theory, but my card is PCI-Express, which should not have anything *like* data transfer problems. Indeed, the bus to a PCI-E 16x card is SO wide, that it can actually be used for a video card's access to system ram instead of needing onboard ram (in the case of ATI's Hypermemory and nVidia's Turbocache technology).

You are probably close on this, though - but if it's not the bus....what could it be?

And this is especially odd on the X800XL, as it squeals by default, but turning ON 4xFSAA and 4xAniso fixes the problem. Which *surely* would INCREASE whatever data transfer load there is?

Actually, you'd be surprised how much in common they are. For example, you can simply copy all the SC DLLs over the DW DLLs, and the game still works (although obviously many interfaces won't work, and platforms...but the functions are obviously identical between versions, or the game wouldn't launch at all).
