I noticed it the past few days as well. I (almost nightly) update my wine via git and the past week or so performance has drastically dropped in GW. Code: fixme:d3d_shader:shader_glsl_load_constantsF >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from glUniform4fvARB() @ glsl_shader.c / 231 fixme:d3d_shader:shader_glsl_load_constants >>>>>>>>>>>>>>>>> GL_INVALID_OPERATION (0x502) from glUniform4fvARB @ glsl_shader.c / 411 This floods the terminal while making the game nearly unplayable, if it doesn't just simply exit like you said. I have the full version, and up untill recently, worked flawlessly for me. (been reading this here mailing list for months, first reply - learned a lot through this stuff!)[/code]
