Early in November the Oibaf PPA in Ubuntu Utopic switched over to the new mesa 10.5 builds. I am running Ubuntu Vivid but the PPA has yet to add Vivid and generally in this stage of an alpha the PPA's from the recently released version work fine. Anyway, I fired up the game scorched3d for the first time in a while and found ugly problems. First, the game locked up on loading skins for the tanks. Last time I saw this it was a hyper-Z bug, so I tried disabling hyper-Z, it did not help. Perhaps this is an issue with a single OpenGL extension?
I could enable everything in the game except the tank skins and it would work, but framerates plummeted from the 50-60fps range down to 18-22fps. Perhaps the splash screen is the most repeatable, it dropped from 24fps down to 8-11 fps.
Next I fired up Criticalmass (executable is called critter). This 2d game in opengl gives very fast framerates that drop with the number of sprites on the board. The least loaded framerate dropped about 15%, but the max loaded framerate roughly cut in half.
Where should I file the bug report for this against the Oibaf PPA version of Mesa 10.5? In the meantime I've rolled back to mesa 10.4 and gotten back all the performance, verifying that the problem has to be in one of those packages.
