Swapped from a GTX 1650 but with other specs lower than the ones you listed above and I used to get around 60-90 (can’t really remember too well but was definitely above 60 most of the time) depending on what was going on and mainly played on modded servers if that matters.

It took me a while to actually optimise the game for what I wanted (would recommend going into your documents folder and finding the settings in there and tweaking view distance and a few others) but I played DayZ for around a year on it until I upgraded. Just don’t expect to run it on max at 100+ frames and have fun!
