How to fix character clipping through walls in Monster Hunter Wilds with Corsair Vengeance LPX DDR4 3600?

Physical collision scenes in Monster Hunter Wilds often had characters passing through walls, making combat absurd and breaking immersion. I tried rolling back to an older driver version, but the system blue-screened, causing pain and complaints about the trial-and-error process. I used the GamePP System Backup and Configuration Export Tool to fully backup the current stable driver configuration and manually supplemented missing registry items. A rollback test confirmed that restoring from the backup normalized physical collisions, and the game ran stably.
