Intel just dropped its latest graphics driver for Windows, but the 32.0.101.8860 package only mentions support for Arc G3 Extreme chipsets. Yes, the cheaper non-extreme APU technically hasn't made its way to any handhelds yet, but it did officially land alongside its flagship sibling, so support should be on the table.
As a reminder, the Intel Arc G3-series is set to power the best gaming handhelds and challenge chips like the AMD Ryzen Z2 Extreme. Effectively, the Panther Lake APU will reside within premium portables like the $1,700 MSI Claw 8 EX AI+, helping it pull harder fps punches than the chip with the ROG Xbox Ally X, but the non-Extreme version should be powering alternatives that aren't astronomically priced.
