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. ![Sample screenshot](sampler-feedback-streaming.jpg "Sample screenshot") Textures derived from [Hubble Images](https://www.nasa.gov/mission_pages/hubble/multimedia/index.html), see the [Hubble Copyright](https://hubblesite.org/copyright) -The demo requires at least Windows version 19041 and a GPU with Sampler Feedback Support. - -Intel Iris Xe Graphics, as can be found in 11th Generation Intel® Core™ processors, will run this application as of BETA driver [30.0.100.9667](https://downloadcenter.intel.com/download/30522/Intel-Graphics-BETA-Windows-10-DCH-Drivers) - -Note this repository does not contain the textures shown above, which total over 13GB.
