WDDM Scheduler Stress (AlwaysRepatch)
This automated test verifies system stability while running many GPU-bound memory intensive applications when all patch locations are always repatched via the Patch DDI.
This test creates many processes that do D3D9 rendering with a large video memory working set. This causes preemption and paging to occur on the GPU. The test puts the operating system into a mode that causes it to repatch all patch locations via the Patch DDI. Display drivers must not cause the system to crash or stop responding (hang) while running this test.
