Tree of Savior

Argh, I don't know what nice things I can say about the game besides the nice character customization options at the beginning.
From "Corrupted" IPF files to weird FPS drops (My computer is beyond capable of running this and I get like 90 FPS without VSync and somehow it dips to 30 from time to time), those issues really have ruined my expections of the game even for a Beta (2nd wave!).
Does anyone else experience these weird FPS drops :/?

I experienced huge FPS drops and have resolved it in two ways:

1) between the first CBT and this CBT, my nvidia graphics card was not being used when tree of savior was running. It took me a while to realize this, and once I did it helped a lot when I forced it on.
2) If you use a dual monitor set up or something like me where you have an HDMI cable out of a laptop in to a monitor, it for whatever reason causes poor FPS
