Nvidia App adds 'Auto Shader Compilation' for faster load times in games — beta feature automatically recompiles shaders in the background after every driver update

The latest version of the Nvidia App has brought a lot of new improvements, with the highlight being the new DLSS 4.5 dynamic multi-frame gen. We've already gone hands-on with dynamic MFG, but the update also introduces another interesting feature called "Auto Shader Compilation." ASC aims to make your games load faster following a GPU driver update by saving you from runtime shader compilation.

Every time a new graphics driver comes out, your GPU needs to recompile shaders for games you've already installed. This process happens when you open the game and can take up to a few minutes, depending on your hardware, which is precious time wasted in this economy. Auto Shader Compilation, as the name suggests, will automatically compile these shaders for you in the background.

The next time you sit down and launch a game, you won't have to wait for the shaders to recompile in front of you. Keep in mind that this feature only works for titles that have already had their initial shader compilation done, so any new game you install will still need to go through the manual shader compilation process for the first time. Every subsequent GPU driver update, though, the Nvidia App will handle things for you.

The feature is currently in beta, so it's disabled by default, but you can go into the Global Settings and activate it under "Shader Cache," where you can also set the storage and resource limits for it. For instance, a 100 GB cache size can store shaders for around 20 modern AAA titles, but usually it's much smaller than that. You can allow either low, medium, or up to a high degree of system utilization for this process as well.

Nvidia says "this beta is the first step into optimizing shader compilation for GeForce gamers," likely hinting at Advanced Shader Delivery (ASD). Microsoft introduced ASD last year on the ROG Xbox Ally and recently made it a part of the DirectX SDK, with all major industry players set to adopt it. Intel has already launched "Precompiled Shader Distribution", but that isn't built on top of Microsoft's framework just yet.

ASD paves the way to a future where the need for local shader compilation is drastically reduced. Soon, by leveraging precompiled shaders stored in the cloud, GPU manufacturers will be able to prepare a game ahead of time for users without any manual intervention. You won't even need to wait for shaders to compile for the first time; the idea is that they're already compiled in the background according to your specific hardware config and distributed over the network when needed.

Nvidia's Auto Shader Compilation doesn't completely eliminate wait times, but it should help users make the most of their limited gaming time by doing shader compilation work ahead of time (at least after the initial compile).
