One thing i've noticed (and i'm sure many others) is the overall processing speed of the game, including rendering, in FM18 is much slower than in FM17.  Is that just because it's beta?  I certainly hope so cause it sucks the fun out of the game when it's so slow compared to FM17.    Also a lot of choppiness while it's processing, you can see that little circle that's processing being all choppy oppose to being super smooth in FM17.
