AMD Driver Bug Silences Smart Access Memory, Crippling Windows 10 Gaming
TL;DR Summary
A driver bug is silently disabling Smart Access Memory (SAM) on Windows 10, leading to lower gaming performance, crashes, and inconsistent behavior. Users report SAM/Resizable Bar being turned off in Adrenalin despite BIOS settings, and Windows sometimes not detecting Radeon GPUs after updates. Workarounds include a clean DDU-based reinstall in safe mode, offline driver installation, and re-enabling VRR, though results vary. AMD is investigating and has previously pushed a preview driver to improve Windows 10 compatibility while a fix is developed.
