--- Comment #66 from Tobias Jakobi liquid.acid@gmx.net 2011-01-09 12:12:25 CST --- At least not for me: Like I said I checked this, but my issues won't go away by reverting that commit.
However my issues are not really the same: I now have these blueish (!) artifacts on the player skin, which also appear in some other games. Maybe this isn't really related... probably also I driver bug, I can't say that for sure.
And we know that nvidia drivers work a bit different than the rest. In the end it all boils done how the driver's compiler (and of course the harsware) handles NaN results.
@GyB: You should ping Henri about that, since it's his patch that reintroduced the issue. To be honest I have no clue how to solve this issue in a clean way. Probably the best idea is some GL extension which toggles the behaviour (D3D vs. GL NaN handling).
