When my mate finally got in DK1(and we finally got HL2 working with it) I found the load a terrible user experience.  Going from head tracking and immersion to a sudden frozen image that is fixed in your view while your head moves.. Crazy vertigo.  I didn&#x27;t really get sick from it, but it definitely was not the most fun I have had playing a game.<p>These things will get sorted out relatively quickly though I imagine.
