I write a MapEditor and implement PSSM(Parallel-Split Shadow Maps into my MapEditor(DirectX9, VC++). My lowerclassman write a game with DirectX9 and VC++. I implement PSSM into his game, but the shadow seems to have some alisings in his game. We use the same camera parameter (excludes the camera position and look at). His game use deferred shading to render the scene. I restore the screenshots of ours as below:

Could somebody know the cause of the difference of ours? And how to I solve this problem?
