+# Sampler Feedback Streaming
 
 This repository contains a demo of Sampler Feedback Streaming, a technique using sampler feedback to guide loading of tiles of a reserved resource on-demand per-frame. This allows scenes containing 100s of GBs of resources to be drawn using much less physical memory. The scene below uses just ~200MB of a 1GB heap, despite over 350GB of total texture resources.

+By default, the application starts looking at a single object, "terrain", which allows for exploring sampler feedback streaming.

 There are also a few known bugs:
 * entering full screen in a multi-gpu system moves the window to a monitor attached to the GPU by design. However, if the window starts on a different monitor, it "disappears" on the first maximization. Hit *escape* then maximize again, and it should work fine.
 * full-screen while remote desktop is broken *again*. Will likely fix soon.
