WDDM Max Contexts
This automated test verifies that drivers do not have any hardware limits on the number of rendering contexts that can exist at any given time.
The WDDM Max Contexts test creates 100 user-mode device contexts at the same time. Drivers fail the test if they fail any of the device creation attempts. The number of outstanding device contexts that exist must be limited by available system memory only.
