The 128x and 64x version of Optimum Realism is free to play. Optimum Realism is a realistic resource pack that tries to replace Minecraft blocks with their real-life counterparts themselves with a perfect balance between performance and quality, not only does it try to widen the spectrum of imagination between a game and real-life scenarios but also, elaborates on most objects that signify their importance better than we would notice rather than just 'adding them' as they would be in real life.
