HOW TO SOLVE RENDERING THREAD EXCEPTION ERROR(CRASHES ON LOADING SAVE GAME) IN BATMAN ARKHAM CITY?

IT IS DUE TO SOME LOCATIONS(like park row) IN GAME WHICH CANNOT LOAD AFTER RESUMING IN CERTAIN PCs.So back up your save file before and after that location which is not loading and repeat it until you completes the game,thats the only way.Other methods shows in net do not works for me.Which means if park row is not loading then take a backup of save file before park row and you should exit the game after the park row location.
