I used to play on a very low end computer and now I play on much better one. One thing I saw was that more bugs are happening on low end computer (wow thanks sherlock) but also the more you try to gain fps by downgrading your setting the more they appear.
Maybe you're already doing this but try on a 4gb ram pc with super low settings and client that close when game launch
We try to test on a variety of machines from highest end to toasters - but I think it's a good call out. I'll look into the setting quality and the 'close client when game launch' options. Thanks :)
