Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=44863
The bug has been fixed already by moving ddraw4 vertex buffers into system memory. Changing this value makes the game create a smaller buffer, which makes the game fast on video memory buffers. I think we should stay close to what Windows drivers report even though we mitigated the original issue in a different way.
-- v2: ddraw: Set dwMaxVertexCount to 2048.
