I had initially set out to build a system capable of handling about 3 instances of Diablo 3. The plan was to build a few of these systems at the onset, and add more later should the botting prove fruitful.
When Hellbuddy announced that their bot would come with a renderer disabler, I chose a difference approach. Each game will now require far less CPU/GPU brawn than before. With that in mind, I set out to build an even more efficient PC, one that could run a larger number of Diablo 3 instances. My hopes are that, by investing a little more, one could drive down the cost per instance. The system will still run fewer instances of Diablo 3 with the renderer running, so it can still serve its purpose even if the renderer disabler does not pan out.
I based the build on the minimum system specs released by Blizzard. I also assumed that the rendered can be disabled for 300% performance gains - though this has yet to be benchmarked. AMD parts were selected for this build - as they have...
Hellbuddy bot, supposedly the first working Diablo 3 bot to date, has released a gameplay video. The video shows a wizard using a small mix of abilities to play through preliminary stages of the current Diablo 3 beta:
Within the semi-private Hellbuddy forums, more details have been released:
The bot includes a launcher. The user is required to input a user name/password, amongst others.
When Diablo 3 crashes, data is submitted to Blizzard. Hellbuddy bypasses this procedure by immediately shutting down D3's data submission process.
Extensive automation has already been implemented: looting, destroying, stashing, selling, dodging projectiles, disenchanting, buffing, and of course, killing monsters.
Includes a renderer disabler. This improves in-game performance by 350-450%. Great for running multiple instances of D3 on a single machine.
