Everyone have this bug. Literally every person who are playing diablo 4. No exceptions. The more powerful your GPU is, the more effect you gonna see. Of course settings are a factor too (resolution, dlss and so on), so not all gonna “see” same results, but still.
If you are using 1060 with 120W tdp, going from ~60-70w during normal gameplay to ~110w when opening vendor is not a big deal.
Then person b using 3090 and he is going from ~150-200w to 400w just by opening vendor. This is big deal. Blizzard don’t give a damn, they are ignoring it for months now (not only since release, but open beta too).
