It's been a rocky road to market for Intel with its Arc range of graphics cards... and just over a year since Intel talked to us about it. In this extended interview, Alex and Rich talk to Intel Fellow Tom Petersen about the state of play with Intel Arc, what's going on with DX11, DX12, Vulcan and Resizeable BAR, plus there's new information on XeSS upscaling (which we're currently testing) and what Intel says is best-in-class ray tracing performance.
