Console log

Since patch 3.0.2 (relatively recent beta build, didn't happen until late
September), loading the game under d3d mode crashes on login with the error
below. After some discussions on IRC, it seems this is related to the following
line:

err:d3d:getColorBits Unsupported format: WINED3DFMT_R32F

Attached full console output. Problem has only been seen so far on nVidia 86xx
and 88xx cards. Changing to double buffering and MultiSample to 1 does not give
any better result.

8600 gts, driver version 177.80

This application has encountered a critical error:
