D3DDEVINFO_VCACHE Structure

Vertex cache optimization hints.

Syntax

typedef struct D3DDEVINFO_VCACHE {
    DWORD Pattern;
    DWORD OptMethod;
    DWORD CacheSize;
    DWORD MagicNumber;
} D3DDEVINFO_VCACHE;

Members

Pattern

Bit pattern. Return value must be the four-character code (FOURCC) ('C', 'A', 'C', 'H').

OptMethod

Optimizations method. Use 0 to get the longest strips. Use 1 to optimize the vertex cache usage.

CacheSize

Cache size used as a target for optimization. This is required only if OptMethod is 1.

MagicNumber

Used by internal optimization methods to determine when to restart strips. This cannot be set or modified by a user. This is required only if OptMethod is 1.
