Silent Hill HD Collection will be patched to correct framerate and audio syncing issues, while Silent Hill: Downpour will receive a fix for an auto-save bug in the game.
Konami did not mention whether the patch would replace the fog effect in Silent Hill HD Collection.
The fog effect was significantly reduced in the HD port of Silent Hill 2, revealing unfinished textures and level pieces the effect was meant to hide in the PlayStation 2 original.
Silent Hill HD Collection and Silent Hill: Downpour both released last month on Xbox 360 and PlayStation 3.
Konami said the patches will be available "in the coming weeks".
