Nowadays 2 seconds is an eternity considering M.2 drive speed and DDR4 bandwidth. Baldur’s Gate 1 for example, nothing is compressed and load times are in single digit milliseconds. Sure BG1 is loading like 1/8th the stuff but load times are 1/300th
There’s actually a program people use for D2R to unpack textures and it cuts load time significantly, but the install and the uncompressed files have a massive footprint
