c# optimization

Is there any way to make this faster? C# on the Xbox (XNA) - for those that don't know the CPUs are shitty PowerPC cores, and is slowwww.


toDraw = redBulletList.Count;
if (toDraw > 0)
{
    Array.Resize(ref instanceTransforms, toDraw);
    for (int i = 0; (i < toDraw && i < redBulletList.Count); i++)
    {
       instanceTransforms[i] = redBulletList[i].Transform;
    }
    redBulletInstance.DrawInstances(instanceTransforms, _viewMatrix, _projectionMatrix);
}

This will not be repeated.
