1420 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1421 US$10,000 to the Mesa project to support its continuing development.
1422 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1423 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1424
1425 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1426 improve performance on 3d hardware.  Thanks to Keith's work, many
1427 applications using Mesa 3.1 will see a dramatic performance increase
1428 over Mesa 3.0.  The donation will allow Keith to continue working on
1429 Mesa full time for some time to come.
1430

1432 information about id Software, Inc. see www.idsoftware.com.
