Nvidia has released a new GeForce Game Ready driver, with Version 591.74 WHQL introducing support for the company’s recently announced DLSS 4.5 technology. The update centers on an enhanced DLSS super resolution Transformer-based Artificial Intelligence model that is designed to deliver significantly higher image quality than DLSS 4, which in itself was described as a major improvement over previous DLSS versions that relied on convoluted neural networks (CNN) based models. This positions DLSS 4.5 as the latest step in Nvidia’s ongoing effort to refine image reconstruction and performance scaling for supported games.
Alongside core driver-level support for DLSS 4.5, GeForce 591.74 enables new Nvidia App DLSS overrides that allow players to select the updated technology even when a game was originally designed for DLSS with an older model. This override capability is intended to give users more direct control over the specific DLSS version they want to run, potentially improving visual quality in existing titles without waiting for per-game patches. The driver update also delivers improvements to Nvidia Surround settings, which are used to configure multi-display gaming and productivity setups, enhancing the overall configuration experience for users with multiple monitors.
The GeForce 591.74 WHQL release further broadens G-SYNC monitor support with the addition of dozens of new monitor models, reflecting Nvidia’s continued expansion of its variable refresh rate ecosystem. Stability has also been a focus in this update, with the company stating that game stability issues with ‘Arena Breakout: Infinite’ have been fixed. Users interested in the new DLSS 4.5 capabilities, improved Surround options, expanded G-SYNC compatibility, and the specific game stability fix are directed to download the updated GeForce 591.74 WHQL driver from Nvidia’s official distribution page.
