--- Comment #10 from Stefan Dösinger stefandoesinger@gmx.at 2011-06-20 14:16:17 CDT --- Yes, it looks like you enabled strict draw ordering correctly. Please make sure you don't have an AppDefault key setting it back to disabled for iw4sp.exe and iw4mp.exe. If such a key doesn't exist I'm afraid this bug is different from what I thought :-/
