Intels new Arrow Lake CPUs came out in October promising high performance at lower power levels, but reviews, including ours, noted surprisingly lackluster gaming performance. Tom Warren said of the Core Ultra 9 285K, ...in many titles, it provides worse performance than the 14th Gen chips it was designed to replace.Now, the troubled chipmaker says it has been gradually releasing updates that fixed most of the issues it identified, as reported earlier by Toms Hardware.At the end of the day, there were four root issues that we needed to address, and fixes for those are actually already in the field right now, Robert Hallock, Intels VP and GM of client AI and technical marketing said during an interview with HotHardware. Theyve been coming out over the last two weeks or so in drips and drabs, as update schedules allow.One issue stemmed from a mistimed update that was supposed to optimize Windows processor power management (PPM) system for Intels Core Ultra 200S-series processors. (PPM adjusts the performance of a CPU based on the current power plan, such as Balanced, High Performance, Power Saver, etc). RelatedWhat happened to Intel?Instead of releasing the PPM update before reviewers got their hands on the processors, Intel says it scheduled the update to go out when it became widely available, which may have caused reviewers to see worse-than-expected performance. Due to the missing PPM update, Intels performance-boosting Application Performance Optimizer (APO) also couldnt take effect in games, while misconfigured performance settings also had a negative impact on reviewers benchmarks.

Intel also says Epic Games resolved a driver compatibility issue causing the blue screen of death when running games with Easy Anti-Cheat, such as Star Wars Outlaws.Intel is planning to release another set of performance upgrades for Arrow Lake CPUs in January, and it will provide a comprehensive performance update at CES. For now, Intel recommends updating Windows and applying the latest BIOS update to your motherboard if you havent already. Otherwise, you can wait until the final performance update next year.
