PC Gaming Alliance, the non-profit organization who has been both promoting and trying to improve the PC gaming industry, may have lost two of its founding members. The official PC Gaming Alliance web site no longer shows Microsoft and Nvidia listed as members of the group. In addition another founding member, AMD, is now listed as a contributing member of the organization rather than the higher Promoters membership tier.
The PC Gaming Alliance was first announced in 2008 during GDC and since then a number of members have both left and entered the organization. However if Microsoft and Nvidia have indeed left it would be the biggest defection that the group has had since it was first formed. We have contacted the PC Gaming Alliance's president Matt Ployhar for comment along with Microsoft and Nviidia
