Furthermore, the tool solved a critical problem of fidelity versus performance. PES 2021 is a game from the era of the PlayStation 4 and Xbox One; its native texture resolutions are modest. Modern hardware, however, can handle 4K and even 8K textures. The Ftex Converter allowed modders to import high-resolution .dds files with custom mipmaps, dramatically improving visual clarity without crashing the engine. Kit textures became crisp enough to see individual threads; turf textures became so detailed that they mimicked real-life grass density. The converter effectively future-proofed the game, allowing it to scale to high-end PCs in a way Konami never envisioned.
