no offense, but i disagree. i just recently upgraded from my 1080ti. that was a “not bad” card. but the 1060 was super low end even when it released 9 years ago. i am really sorry to tell you, but that upgrade might be super overdue lol.
i hope u have at least a decent SSD, at least 16GB RAM and a reasonable CPU.
in any case tho, the dev team asked to get them log files if people encounter performance issues: How to Properly Report Bugs!
thats the only way how they can investigate whats going on
