Aside from performance improvements, I believe that this update is genuinely necessary for proper 3D peformance. Using Feisty's latest packages, vertical sync doesn't function properly at all, with jerky movement and tearing still present.
Test yourself if you have an Intel card; run an opengl app that features 2D side-scrolling (in this case, I tried the emulator gens w/opengl, running Sonic), and compare normal output with "vblank_mode=3" output; vertical sync doesn't seem to work properly at all. -- Request: sync new agpgart & drm modules for 50% DRI performance boost with Intel users https://launchpad.net/bugs/88918 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
