ATI Radeon HD 5450 is more than good enough for WOS. The CPU should be good enough too. If you experience troubles within these games, it has to be the coding for the game. Even with my High End setup, I still bump into unnecessary problems. If Spider-Man Shattered Dimensions shutters, then set on Adaptive Vertical Sync. Fixed it for me. If it lags it usually are two reasons. 1. The hardware isn't good enough. 2. The hardware is too good and your monitor can't keep up with the FPS. If the FPS are beyond 60 and you use a 60 HZ monitor, it will shutter. Adaptive Vsync fixes that problem.
