Iain pointed me to
this BFG page
when he told me I could buy a PhysX card for my PC.
He said it didn’t seem to be available in Canada.

which is a bit steep considering it only costs $300 in the US.
$CDN/$US is currently at 0.9085, so if I buy it here (ignoring costs of converting currency),
it would “only” cost $330 or so.
