I'm sorry to hear you're having issues with lag. Have you tried reducing your video settings? Lowering the Grass Density, Draw Distance, Shadows, and Water Quality settings can all have major impact on performance.
Additionally, Adapt is not optimized for on-board GPUs. So you will likely see graphics latency if you're using a laptop with and Intel onboard or other similar GPU.
Thanks for your feedback, and I'll be sure to double check the game's min system requirements to make sure they are accurate.
