The new Geforce 458.38 WHQL Game Ready driver is now available for download, and it brings several improvements as well as some big changes.
To be precise, Nvidia has disabled "Implicit SLI" support on Ampere-based graphics cards but also announced that new SLI driver profiles won't be available after January 1st, 2021. This does not necessarily mean that multi-GPU support is dead, as thanks to DirectX 12 and Vulkan APIs, multi-GPU support can be enabled by game developers, or so-called "Explicit SLI".
As explained by Nvidia, "Explicit SLI is still supported, where the application knows the SLI state and uses extensions (such as DirectX 12 linked nodes, Vulkan device groups, or OpenGL multicast extensions) to issue commands to each device in the SLI group".
Currently, only RTX 3090 supports SLI, so it will be hard to convince game developers to go for it.
In addition to the support for GeForce RTX 3080 and 3090 GPUs, the new driver also adds GeForce Experience Automatic Performance Tuning for GeForce RTX 30-series and RTX 20-series, GeForce Experience in-game performance monitoring for GeForce GTX 600 series and above, ShadowPlay gameplay recording now supports HDR on GTX 900-series and above (RTX 3090 can capture 8K 30fps HDR), NVIDIA Broadcast app with AI-powered noise removal and virtual background, and five new G-Sync compatible monitors (Acer XV253QGW, ASUS VG27AQ1A, LG 27GN800, LG 27GN600, and ViewSonic XG270Q).
When it comes to Game Ready side of the new driver, it adds support for Mafia: Definitive Edition and Halo 3: OSDT. It also adds support for the Nvidia Broadcast App, support for Nvidia Reflex in Valorant and Fortnite, support for Fortnite RTX, and more.
As always, you can find the new Geforce driver over at Nvidia's own support page.
