Type: Automated Test

Overview

The WDDM Scheduler Stress (No PrePatching) test verifies system stability while running many GPU-bound, memory intensive applications when pre-patching of DMA buffers is disabled.

Details

The WDDM Scheduler Stress (No PrePatching) 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.

Run Time: 30 minutes

System Restart Required: No

Supported operating systems for Logo or Signature testing:

  • Windows 7

  • Windows Server 2008 R2

  • Windows Vista
