I have a pretty high end pc and i average 180 fps with shaders (iris and sodium) the last update and as i updated everything and entered my hardcore world i was seeing bottom 30-45 fps9on deafult and OpenGL) vulkan works swell but i would really want shaders and my previous performance!!
Thank you for your report!
