Hardware specs and terminal output

I noticed that suddenly games were very slow (it takes seconds just to
highlight a menu item). I tested Shadow Warrior 2 and XCOM: Enemy Unknown. The
first game I had never tried, but I know the performance of the second one.

I downgraded wine-staging until I got a working version: 3.15. The other
versions tried were 3.17, 3.18 and 3.19. The terminal output is attached. The
output refers to XCOM, launching the game up to the menu and exiting.

Also attached are my hardware specifications.

Thank you very much for reading this.
