Had two insignificant problems:

1. origin was stealing focus and kept alt+tabing from the game from time to time. However, it could be related to my tiling WM and inability to set game folder in origin, which made it to popup window with same question again and again.

2. Slow game launch. Had to wait for like minute or two with an empty, white origin window, which can be mistaken with a freeze.

.

Everything else was totally fine.
