--- Comment #7 from ariel cornejo arielCo@gmail.com 2011-06-27 08:10:18 CDT --- Uhm, let me elaborate: with HW_OK=1, I launch SketchUp more-or-less successfully (the work area is initialized with garbage and I need to zoom in/out to refresh but otherwise it works). Then I try to disable HW accel as described in comment #1 and SU crashes when I click [Ok].
If I set HW_OK=0 it refuses to start: "SketchUp was unable to initialize OpenGL! Please make sure you have installed the correct drivers for you graphics card. Error: ChoosePixelFormat failed [Ok]". Then it creates an "Untitled" window, closes it immediately, and another MessageBox shows some unprintable text like "▯▯▯▯▯▯▯ (▯▯▯▯▯▯:59)" followed by "An invalid argument was encountered".
I'm guessing that it takes something else to switch to software rendering via registry.
