According to rather extensive release notes, the new Arc GPU 101.5379 Beta driver adds Game On support for those four games mentioned above, but also adds impressive performance improvements reaching anywhere from 172 down to 6 percent on Intel Arc A-series graphics products. The games that these improvements come to include the new Dragon's Dogma 2, Horizon Forbidden West, but also Assassin's Creed Origins, Fortnite, God of War, Sons of the Forest, and others.
Intel has also improved performance on its Intel Core Ultra CPUs with Intel Arc GPUs in those same games.
The new Arc GPU 101.5379 Beta driver also fixes a couple of issues, including crashing in Counter Strike 2 and DOTA 2 on Intel Arc A-series GPUs and issues with Alan Wake 2 and Serif Affinity Photo 2 on Intel Core Ultra CPUs with Intel Arc GPUs.
