Its also been affecting me on the stable build, have tried reseating the cooler and dont experience any problems on other games. The second i load into a infinite world my cpu usage hit 100% and cpu temps hits 85c. When i use rtx templates everything runs fine and cpu usage is resolved. I have included screenshots with cpu/gpu utilation in both cases
