* can be misleading. In fact, that flag gives no such indication. I pointed this
* out to Bas in my email. However, Microsoft is in fact using this flag to
* indicate "light weight" DX applications. By light weight they are essentially
* referring to applications that are not games. The idea is that when you create
* a DX game, the driver assumes that you will pretty much have a single instance
* and therefore it doesn't try to hold back when it comes to GPU resource
* allocation as long as it can crank out performance. In other words, the
* priority in regular DX applications is to make that one application run as fast
* as you can. For "light weight" applications, including D2D applications, the
* priorities are a bit different. Now you are no longer going to have a single
* (or very few) instances. You can have a lot of them (say, for example, a
* separate DX context/device per browser tab). In such cases, the GPU resource
* allocation scheme changes.
