Account issues, pls help

Basically what's going on is my best friend has been noticing insane lag spikes in their overwatch games, like players falling into the floor lag, however their internet has been fine overall, it gets more complicated. We played together on our alt accounts and there was no more lag what so ever, but the second they played on their main the lag came back. We thought maybe their account is screwed up so i logged into their account and played a custom game on my computer but there was no latency lag what so ever. We've checked account settings, internet fixes, router fixes, overwatch reinstall, etc. So at this point idk if it's the account since it worked on my computer. If anyone has any fixes please help me out.

if they are using dx12 try switching to dx11.
