So Ylands has been running really slow for me lately (35 hours into the game), to the point where the program froze and made me force quit. I only lost about an hour of progress but frustrating none the less. Did some research and decided to move my game from HDD to SSD. Now i have other steam games on my SSD drives, so Lord knows why i didn't with Ylands but HOLY CRAP. So much smoother. Its like night and day. No more lag when i'm searching for items to craft in the inventory.
Long story short, put Ylands on an SSD. That is all.
