It is time that Blizzard admits there is some issue instead of sending users down a path of trying a million different options that have not actually fixed the issue for anyone.
I have a RTX 2080 TI with an 8700k in my home PC that started getting this issue after updating from a 1080. Nothing is overclocked at all. I have formatted my computer, installed all of the latest updates and drivers. Disabled 3D Acceleration on everything that might utilize the GPU (browsers, etc.) No apps are creating an overlay ingame, including Geforce Experience. Closed all extra apps that are running and I constantly get these errors once or twice a night, I literally cannot do competitive because of this and I have been googling this same error for months now.
To top it off, I bought an Acer Predator 500 laptop the other night ($2500- has a i7 8750H, RTX 2080 in it) and I am now getting these same errors on the laptop.
Does Blizzard have this issue with their code documented is actively pursuing a fix?
