Hi, since the last update when playing Hearthstone it seems to have high power usage of my PC. The coolers and fans turn up heavily like I was playing a game like Battlefield or GTA. That has never been the case before. I only play Battlegrounds.
Is this a known problem and is there anything I can do?
Thanks!
Same here… maybe they added a secret mining app wich uses your GPU to mine BTC for blizzard. At this point i wouldn´t be surprised anymore tbh 
Not sure if it’s related, but since the last update every time I play Battlegrounds on my iPad, I get the warning message about needing 2GB of memory on my device. Which is weird, both because it says that Battlegrounds is still in Beta, and because I replaced my old iPad with a new one last year. I had been playing Battlegrounds for months without issue.
I have same problem, haven’t figured out why
Same for me… for some time now.
Laggy and stuttering as well.
Same here with me, it has been crashing my PC (550 Watt power supply)
Hello, i have the same Problem. I have a 2080ti and Hearthstone uses over 90% of my GPU… I am using the newest drivers and optimized Seettings. I have a 4k Screen and plying on 3840 x 2160 with High Quality Setting.
I put the FPS Lmit to 60 in the nvidia Settings and added the lines in the options.txt: targetframerate:i=60
vsync:b=False
Now Hearthstone only uses about 10% GPU. I hope it stays this way.
