I knew something was up. I wondered why opening any basic project takes 3 minutes to load and shaders sometimes takes half hour to compile. Its ridiculous. Working in the material editor is sluggish, every node change takes 5 seconds to take into effect. Hitting apply leads to another 5-10 wait.
Its ridiculous. UE4 was way faster years ago (back in 4.8) and i had GTX 970. Now its sluggish with 1080?
Today i installed UE on my work MacBook pro and loaded up the same project. Its took SECONDS to open up. SECONDS!!!
My workflow on the macbook is 30x faster than a desktop with GTX 1080, top of the line Intel Core i7 and 16 GB RAM. WTF?
