  "account": "A new Windows 11 feature is currently in testing, offering an option to enable Intel's Advanced Performance Extensions (APX) to enhance the performance of certain applications. This enhancement is expected to benefit Intel's upcoming desktop CPUs, with AMD processors set to receive support eventually. The feature was discovered in a recent preview release of Windows 11 (build 29695) by Windows Latest, which shared a screenshot of the APX option in the system settings. APX expands the x86 instruction set with additional registers and introduces new features to boost general-purpose performance, allowing app developers to leverage the technology for increased software speed. However, app developers will need to recompile their applications to utilize APX, and this upgrade is not yet available on existing Intel and AMD processors.",
  "summary": "Existing PCs will miss out on this incoming trick for Intel CPUs which will also apply to future AMD Ryzen chips.",
