I played it start to finish on my deck using the co-op mod to play 2 player with my brother (who lives out of state). I also ran discord in the background on the deck, using headphones and the deck’s mic. Didn’t have any problems at all, super fun.
Keeping my expectations low in the hopes I’ll be pleasantly surprised.
You can see videos of turbohud used with d3 on youtube. It adds, for example, item/skill texts rather than just an icon, more detailed dps meter, and a larger minimap as an overlay, etc. I don’t know if any of it should be considered cheating.
Also, for what it’s worth, the TH4 site says it disables itself when pvp marked.
