[GEM-dev] Frame rate on MacOsX

[Antoine Villeret]

hello,

here I got stable 50 fps on Mac OS X with PdExtended 42.5 (Gem ver: 0.92.3)
and also with Pd Vanilla 0.43 and Gem ver: 0.93.git ddca887 (build on
11.11.11 at 11:11)

Mac OS X 10.6.8 on an unibody macbook pro 13" (intel core 2 duo 2,53 GHz)
and Nvidia Geforce 9400M

Hope this helps

Antoine
