I notice your FPS dropping to 45ish there, For the spec you have it really shouldn't be doing that.
If you had something closer to minimum spec it would be unbearable.
I'm glad you showed your FPS in this video, Thanks!
The video is great as always bro, your enthusiasm is great :) -
"Oh!... My!...Days!... Look at this thing here!" :P - Keep it up mate.
