I recently switched from an NVIDIA GTX 1650 to an Intel Arc B580. Afterwards, I had 100% CPU usage and low GPU usage, but switching to DirectX 12 fixed this. Since then, though, I’ve had issues where portraits in the bottom left by the health bar won’t appear, as well as hero models not being visible in any menus (hero gallery, battle pass, loot boxes, etc.). I found a comment on a thread somewhere saying that doing a Scan & Repair through the launcher fixes these issues temporarily, which it does, but I’d rather not have to do that every time I want to see a new cosmetic I unlock.
Update: I’ve discovered a new issue. After playing for a few hours in one session, the post-game accolades screen had flashing lights. It only happened once, but I think it was enough to cause issues for those with epilepsy. I have a video of it I can provide, just not here as I don’t see a file upload option.
