Hi,
1. I want to know if someone can tell me if it is common to use SSE or the newer VXA to do matrix and vector calculations for games?
2. Does D3DX make use of SSE/VXA when calling functions like D3DXMatrixMultiply or when doing any arithmetic on D3DXMATRIX or D3DXVECTOR? If not, I'm assuming one has to explicitely implement SSE on your matrix and vector arithmetic.
3. If D3DX does not implement SSE/VXA implecitely, where can I start to look into SSE? Apparently Intel has an SSE/VXA lib?
Im currently using D3DXMATRIX and D3DVECTOR to store and manipulate my matrices and vertices and Im just contemplating if it is the fastest structure to use.
