That includes Rocket Lake, Alder Lake, Raptor Lake, and the still pretty-fresh Raptor Lake Refresh lineup. That means every single Intel desktop CPU besides the most recent Arrow Lake generation.What that means in practice: no more Day 0 game support, no new features, no optimizations. Updates will be limited to quarterly drops of security patches as well as, potentially, mid-period updates for critical issues. Recent testing of the Arc B580 with Intel's latest driver set by Hardware Unboxed revealed huge gains on slower CPUs—precisely the kind of systems where Arc struggled before.The background here: ever since launch, Arc GPUs suffered from a notorious "CPU overhead" problem. That shift closed the gap with AMD's Radeon RX 9060 XT, effectively erasing the overhead penalty on mid-range CPUs in that game.
