With the launch of the long-awaited Ampere video cards mostly in the rearview mirror, there are reports on the internet of issues concerning the stability of some of these cards. Knowledgeable Youtubers such as Igor Wallosek of Igor’s lab. Buildzoid from Actually Hardcore Overclocking even posted information on what they feel the problem is. On some cards, it appears the capacitor type behind the socket causing some of these issues. While Nvidia hasn’t made a statement on the failures, some users were speculating that it is more than just a hardware shortcoming on some models with specific, over 2,000 MHz, clocks speeds.
Fast forward to today, Nvidia has released the Game Ready driver, 456.55, that adds Nvidia Reflex support in COD: Modern Warfare, COD: Warzone, and is said to offer the best experience in Star Wars: Squadrons. Nvidia goes on to say it also improves stability in certain games on RTX 30 series GPUs.
According to some Reddit users, they’ve seen their stability issues go away while performance remained the same or improved. Time will tell if the issue is a software/driver and/or a hardware issue.
Below is a list of release notes:
