Enabling r_occlusionQuery and setting r_water to 2 crashes some video drivers. (Actually this problem has been known since 0.0.9)

Confirmed on

  • OS X, GeForce 6?0M GTX
  • Windows?, AMD (Unknown)

Workaround

Disable r_occlusionQuery by setting it to 0. This involves some performance loss because reflected image is always rendered whether the water surface is visible or not.

@yvt
r_occlusionQuery now defaults to 0 as a workaround for the issue #106
