Just some code rewrite. It might help because it avoids at least two jumps.

public ScTreeNode GetNodeForState(int rootIndex, float[] inputs)
{

    ScTreeNode node = RootNodes[rootIndex].TreeNode;

    while (node.BranchData != null)
    {
        BranchNodeData b = node.BranchData;
        node = b.Child2;
        if (inputs[b.SplitInputIndex] <= b.SplitValue))
            node = b.Child1;
    }

    return node;

}
