Disabling Frame Pointer Omission (FPO) optimization

WDDM 1.2 and later drivers must disable Frame Pointer Omission (FPO) optimizations to improve the ability to diagnose customer performance problems related to FPO. This requirement applies to both user-mode and kernel-mode display drivers.

• Minimum WDDM version: 1.2

• Minimum Windows version: 8

• Driver implementation—Full graphics, Render only, and Display only: Mandatory

• WHLK requirements and tests: WHQL FPO optimization check for kernel video driver

See WDDM 1.2 features for a review of features added with Windows 8.
