The global PC games market showed "surprisingly strong growth in 2010", reaching a record high of $16.2 billion (£10b), according to the PC Gaming Alliance.
The figure represents growth of 20 percent over 2009, the non-profit organisation said in its third annual Horizons report, which was prepared by market research firm DFC Intelligence.
The report found that China continues to be the largest and fastest growing market for PC games, with record 2010 revenue of $4.8 billion (£2.95b).
However, mature game markets in Korea, Japan, the US, the UK and Germany all showed growth in 2010. Together these markets increased revenue 19 percent last year to $7.3 billion (£4.5b).
The report concludes that the global PC game business will continue to grow at a pace of nine percent compound annual growth rate to $23 billion (£14.1b) by 2014.
Matt Ployhar, PCGA president and Intel analyst, said of the findings: "The spotlight has definitely shifted back to the PC game market. A few of the biggest factors fuelling this movement are innovative business models making games more accessible with digital distribution, free to play, and online; along with game formats embracing the shifts occurring in the evolution of the PC ecosystem to remain more profitable.
"Large game publishers are looking at digital revenue on the PC game platform as one of their key areas of growth and it is clear that the performance of the PC game market in 2010 is resulting in substantial investment money flowing into the PC game business."
Last week, the PC Gaming Alliance lost two of its founding members, Microsoft and Nvidia.
Yesterday, interactive entertainment trade body UKIE said that progress towards launching a UK chart for digital PC game sales is "gathering pace".
