Performance and optimization problems

Today I was forced to shut down the game and I am taking a pause because of unplayable state of the game.
However, my HW is above the recommended, I tried to downgrade the resolution to 1920 x 1080, turn of the details, minimize everything and neither these changes didn't help. The lags sometimes takes 3-5 seconds and it makes the game absolutely unplayable. Prepare good map/towers takes many hours, within few second I lost it all together with XP.
I will wait for fix.
