AMD Software: Adrenalin Edition 26.8.1 is available now, and the latest Radeon graphics driver for games and PC enthusiasts is a must for those looking to jump into the Call of Duty: Modern Warfare 4 Open Beta, which kicks off this weekend for those who've pre-ordered the game or are subscribed to PC Game Pass. It also adds support for a brand-new RDNA 4 graphics card, the Radeon RX 9050 4GB.

This 4GB variant of AMD's new entry-level Radeon RX 9000 Series GPU is reportedly built for system integrators, with the existing Radeon RX 9050 8GB card being the one that you'll find on retail shelves. In terms of performance, online benchmarks suggest the Radeon RX 9050 falls short of the GeForce RTX 5050, despite its $279 USD launch price.
Interestingly, the driver's Release Notes state that because Cyberpunk 2077 recommends a minimum of 6GB of VRAM, in-game graphics settings will need to be set to low or turned off completely for those "experiencing issues." Basically, the note is almost an admission that 4GB of VRAM isn't enough for modern PC gaming.
