While the upcoming streaming PC game service OnLive remains in closed beta testing, one of its rivals has just receive an influx in new money. VentureBeat reports that Gaikai, announced just after OnLive's reveal in March 2009, has gotten $5 million in venture capital funding.

The funding was revealed in a new Securities and Exchange Commission filing but the notice did not mention specifics on who had offered the company their new funds. The company, co-founder by noted game developer Dave Perry, has been pretty silent of late. The service was previously scheduled to go into closed beta in Europe but there's no word on if the beta has actually started.
