Too many indices for index buffer
The following error message may appear when the game crashes if a lot of geometry is in the current PVS.
This means that too many vertices are being drawn at a single point in time. No more than 32768 vertices can be drawn at a given point in time, due to the size of the index buffer.
Clarify: Indices aren't directly equivalent to vertices; 
HLMV can display how many of both are on a given model.
HLMV can display how many of both are on a given model.
Confirm: Do the 64-bit versions of 
increase this limit?
