Public bug reported: Even if 3D hardware-acceleration normally works, the driver will fallback to software-rendering if an application uses GL_LINE_SMOOTH or GL_POINT_SMOOTH (which of course causes a dramatical performance problem).
I'm using a fully updated Feisty. An example application is Breve (http://www.spiderland.org/breve). This is where I discovered this behavior (http://www.spiderland.org/node/3261). The interesting point is that the same application works fine under Windows XP so the win-driver either is supporting these features or is just ignoring them (which would be a workaround and better than falling back to software rendering). I'm sorry for re-posting this bug but there was absolutly no response on my comments which I added to an older and more generally (bug #79553). This was quite frustrating. ** Affects: mesa (Ubuntu) Importance: Undecided Status: New -- intel945gm missing support for GL_POINT_SMOOTH and GL_POINT_SMOOTH https://bugs.launchpad.net/bugs/133799 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
