Priority: medium Bug ID: 68901 Keywords: regression Assignee: dri-devel@lists.freedesktop.org Summary: wine/3DMark2001: shader generation fails Severity: normal Classification: Unclassified OS: Linux (All) Reporter: gurketsky@googlemail.com URL: http://www.futuremark.com/support/downloads Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
When running 3DMark2001 in wine (1.7.1), the r600 gallium driver (on RV710) fails to generate some shaders. This is a regression:
