Get the 3.1.5 update, and most things vanished. Whatever was in abeyance at the 3.1.4 release was clearly fixed up. The only glitch now is that the graphics get a little scrambled, but the game has a redraw command that clears that up, and they must have expected to need it. The only thing I get a lot of now is this, which seems to be harmless [code] err:d3d_shader:arbfp_blit_unset >>>>>>>>>>>>>>>>> GL_INVALID_ENUM (0x500) from glDisable(GL_FRAGMENT_PROGRAM_ARB) @ arb_program_shader.c / 7082 [/code] Thanks for the conversation. The debugger pass dropped the game speed to about 1/2 of its usual response. Must do a lot, but with the grep after, it failed to show anything at all. I think this can now be dropped.
