Batman Arkham Night has been available for a long time now on PlayStation 4, Xbox One and PC. This latest version, however, has always had optimization problems that the developers of Rocksteady they never managed to fix it completely. Well, the modder SheriefFarouk instead he was successful in the enterprise, understanding the cause of the problem and solving everything.
As you can read from his post on Reddit, the user has in fact understood that the game kept creating new textures instead of recycling those already present, and this was precisely what generated the serious problems of stuttering. SheriefFarouk thus used the ReShade mod and made sure that this did not happen, managing to run the title at 60 fps and without drops. At the moment the mod only works on Steam and not on the Epic Games Store, but it is still a great step forward.
