According to the full release notes, the new Geforce 387.92 WHQL Game Ready driver adds support for OpenGL 4.6, adds Nvidia GameStream support for HDR on Windows 10, adds Fast Sync support for SLI configurations (except for Maxwell GPUs which should stick to any resolution under 4K), implements improvement in full-screen Vulkan applications for 32-bit Windows swapchains and adds support for the DirectX Intermediate Language (DXIL) on Nvidia Kepler and later GPUs, which includes full support for DirectX 12 Shader Model 6.0 and features like Wavemath and DirectX Shader Compiler.
Nvidia was also quite keen to improve the performance of its graphics cards in recently released Forza Motorsport 7, where AMD graphics cards gained a significant lead. According to Nvidia, the gain is anywhere between 15 to 25 percent, depending on the configuration, and this should be enough for its graphics cards to get back on top in this game.
In addition to Forza Motorsport 7, the new driver also includes optimizations for Middle-earth: Shadow of War, The Evil Within 2 and Arktika.1, as well as new or updated SLI profiles for games like Earthfall, Lawbreakers, Middle-Earth: Shadow of War, Nex Machina, ReCore, RiME, Snake Pass, Tekken 7, The Evil Within 2 and We Happy Few. It also adds 3D Vision profile for Middle-Earth: Shadow of War and 3D compatibility mode profiles 2DD for Nex Machina - Excellent, Hellblade: Senua's Sacrifice - Excellent, ARK: Survival Evolved - Excellent and F1 2017 - Excellent.
The driver also fixes a couple of bugs including low GPU usage on SLI and Intel's X299 platform, twitching on full-screen Youtube videos with Fast Sync enabled, various issues with Nvidia Control Panel, random jumping of VR view on HTC Vive and more.
You can find the new Geforce 387.92 WHQL Game Ready driver over at Nvidia's driver support page or get it automatically via Geforce Experience software and it is still available for Windows 10, Windows 8.1 and Windows 7 in both 32-bit and 64-bit versions.
