NVIDIA has today released the latest iteration of its Game Ready driver with the version number 456.55. Marked as a WHQL release, the driver is supposedly going to bring new advancements to the stability of the latest GeForce RTX 3000 series Ampere graphics cards. While the release notes don’t officially mention anything on how it improves, it is already confirmed by a few Redditors that the new driver removes crashed experienced with the past version 456.38. In the latest revision, the support has been added for NVIDIA Reflex in Call of Duty: Warzone and Call of Duty: Modern Warfare, as well as support for Star Wars: Squadrons game. Below is the link to the driver download page redirecting to NVIDIA’s site, and in no time the TechPowerUp download page will be updated as well.
