Hi Török, Thanks. We've detected this issue earlier and I'm working on a patch already. Is WoW working now since Jose's fix? Can we close this bug? (In reply to comment #2) > Is WoW working now since Jose's fix? Can we close this bug? Haven't tested yet, will probably test tomorrow morning. Yep, works @2-3 fps in default d3d mode. With -opengl it says no 3D acceleration found, don't know if its a wine or mesa issue: err:wgl:X11DRV_wglCreatePbufferARB ((nil)): unexpected iPixelFormat(0) <= 0, returns NULL err:wgl:X11DRV_wglCreatePbufferARB ((nil)): unexpected iPixelFormat(0) <= 0, returns NULL |

WoW crashes when runder under wine+d3d if MaxNativeParameters is zero (the default). It crashes on swrastc, softpipe, and llvmpipe. This patch works around the crash, but it changes the default parameter for all drivers: diff --git a/src/mesa/main/context.c b/src/mesa/main/context.c index 1707e22..d8c5dba 100644 --- a/src/mesa/main/context.c +++ b/src/mesa/main/context.c @@ -477,7 +477,7 @@ init_program_limits(GLenum type, struct gl_program_constants *prog) prog->MaxNativeAttribs = 0; prog->MaxNativeTemps = 0; prog->MaxNativeAddressRegs = 0; - prog->MaxNativeParameters = 0; + prog->MaxNativeParameters = 256; } There should be a way to set these limits in gallium/llvmpipe, and the other software drivers that support shaders. P.S.: I think bugzilla needs a Drivers/Gallium/llvmpipe component.
