Following the recent release of the Geforce 310.54 Beta driver for Call of Duty: Black Ops II and Assassin's Creed III, Nvidia has now released a new Geforce 310.61 Beta driver version for PlanetSide 2 and Hitman: Absolution.
The new Beta driver brings all of the fixes seen in previous Beta drivers and, as noted, brings improved compatibility for Planetside 2 and Hitman: Absolution.
As it was the case with the entire Geforce R310 driver lineup, this one also supports all Geforce graphics cards since the Geforce 8 Series.
