Even if this bug-report is quite old, the problem still exists. I (intel i945gm, ubuntu feisty) had problems with software-rendering when trying to use breve (http://www.spiderland.org/breve) even when other OpenGL-apps where hardware accelerated).
There is a forum-entry (started by someone else) where this is documentated: http://www.spiderland.org/node/3261 The problem was the use of glEnable( GL_POINT_SMOOTH ) and glEnable( GL_LINE_SMOOTH ) which lead to the use of the software renderer. After deactivating these lines of code everything worked fine and fast. The same application runs fast and hardware accelerated under Windows XP so I don't know whether this *is* supported in hardware or wether the windows-driver just ignores it. It turned out that the programms in the mesademos package are quite a good test for certain functionality of the opengl-driver. If it helps you I could test all of these on my platform and tell what runs hardware accelerated and what not. under the i810/i915dri driver. -- i915 performance error https://bugs.launchpad.net/bugs/79553 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
