So usually after about an hour of gameplay, the game becomes choppy or I start seeing black artifacts on the screeen, either a thin choppy line through the center or a large black region on the bottom that corresponds to a section of the terrain. My drivers are up to date (last update was in May) and I use a Nvidia 960 with 2GB of memory. Intel Core i7-5820K Haswell-E (6 cores, 3.3GHZ), 16GB of DDR4. I'll try and monitor cpu and gpu temps at the time but honestly Rising World is pretty light on resources compared to heavy hitters which run smoothly on this machine.
Are there any tests I can do?
