WDDM Scheduler Stress (No PrePatching)

  • Article

This automated test verifies system stability while running many GPU-bound, memory intensive applications when pre-patching of DMA buffers is disabled.

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 never prepatch DMA buffers. Display drivers must not cause the system to crash or stop responding (hang) while running this test.
