Type: Automated Test

Overview

The Missing Resource Stability test verifies that a driver can process resource handles correctly.

A graphic driver must ensure that all render targets, textures, and vertex buffers are flushed and are also handled properly before they are released by the system.

Details

In this test, the DrawPrimitive functions are called along with calls to manage resources (such as render targets, textures, and vertex buffers). If the driver incorrectly processes the resource handles, the attempts to render the target result in missing or inappropriate resource pointers.

The test calls DrawPrimitive, releases the resource (the test expects that the drivers flush the resource properly), and calls the IDirect3DDevice9::Present function. If the resource has been flushed properly, the primitives are present.

Command Syntax

Command option Description

-multisample

The test clears the multisample render target and then creates and releases the texture immediately (without loading the image).

-texture

The IDirect3DDevice9::Present method is called when the texture resource has been released.

-buffer

The IDirect3DDevice9::Present method is called when the vertex buffer has been released.
