The "Minimum" requirements reflect essentially what you'll need to play in single-account mode. For multi-account play, we suggest you check the "Recommended" requirements.
One client currently takes 2GB of RAM when launched. Therefore, if you intend to play with 8 accounts, you will need to have 32 GB of RAM (8 accounts x 2 GB, not counting Windows and any other processes that may be running).
Since update 1.79, it is no longer possible to launch the 32-bit client on the machines concerned.
DOFUS Touch can only be played on tablet or smartphone, not on devices like Chromebook, Mac M1, etc.
