Very badly.

Some historians estimate that as much as 50% of the population died,and there was widespread devastation and destruction of towns,cities,and agricultral land.

Austria was the heart of the Austrian Hapsburg ruled Holy Roman Empire,and as they lost the war,they were in no condition to take advantage of anything.

Prussia didn't exist as such - it was a fief of the King of Poland that the Electors of Brandenburg had inherited through marriage in 1618,the resulting state being known as Brandenburg-Prussia.They had pulled out of the war in the 1640s as a result of the devastation caused to Brandenburg by it,and it was only slowly,under the rule of the Great Elector Frederick William (ruled 1640-1688) that Brandenburg-Prussia grew in strength and power and became a major (but still not yet the major - Bavaria and Saxony were far stronger and important) German state.

It was total destruction. In average 1/3 of the population had died. But in some cases it was a lot worse. In Magdeburg (then one of the biggest towns) only 500 out of 30,000 survived the siege and rape of the city.

There had been no regualar economy for a generation. Nearly 2 generations had known nothing but war. Farmers did not grow crops, because they were destroyed of taken by soldiers anyway but rather because soldiers themselfs ==> The famine grew and grew.
