The First Descendant Patch 1.0.2, which launched on July 11, has brought many great improvements to the game but also a nasty memory leak that causes the game to crash on almost every platform.
After the patch went live, The First Descendant players started reporting crashes after longer play sessions. Apparently, the game loads up the required amount of VRAM but continuously uses up more. Depending on which console you are playing on or how powerful your GPU is, the memory leak can take anywhere from two to five hours to cause the game to crash.
