No worries at all, I understand the specs you're working with. Like I mentioned, the game is fairly graphically intensive for what it is, but I’ll admit there’s definitely room for me to improve optimization too. Out of curiosity, did you try lowering the resolution to 1600x900 and running it on medium settings in fullscreen? That might help performance a bit.
Hey man! Released a brand new optimisation, QoL and content update! Definitely check it out and see if it runs any better! I've tested on both my desktop and even my ASUS Vivobook laptop where it runs smoothly at high settings + native res. Experiment with the settings and see what you get but definitely stay away from low if you can help as it ruins the atmosphere lol.
