Mac OS X 10.3.4 Update to Help Games
8:02 AM | Eddie Park | Comment on this story
Gamers wondering if the latest update to OS X contains anything meaningful for games development may want to take a look at The Brad Hole, a blog maintained by Brad Oliver. One of his latest entries includes some information regarding a new OpenGL feature that seems to improve performance when used.
Apple released MacOS 10.3.4 today, and it includes a new OpenGL feature called "vertex buffer objects" or VBO for short. It's essentially a method of storing vertex data directly on the video card to eliminate CPU overhead. Apple had implemented a similar extension in the past, called "vertex array range" (VAR) that was essentially a reworking of the Nvidia extension of a similar name. The main difference between VBO and VAR (aside from the API looking fairly different) is that VBO is a cross-platform, ARB-approved way of achieving the same speed-up.Also posted in the blog entry are the results of some tests with both Call of Duty and Star Wars: Knights of the Old Republic. Oliver adds that future game releases should see shorter development times when implementing VBO.
