First of all, put TF on your SSD because the HDD has more or less not more than 80-90 MB/s – read/write performance, and have a huge response time. (that can cause lags)
This the only thing, that you can do at the moment – sorry ;(
We/you must wait for the patch, which will fix the problems with the performance (hopefully)
And sorry for my english, i am an older man who learning english since 5 months 😛
