Punching H'el into space. Lifting chunk of a frozen city while being weakened from red sun radiation--very similar to his stunt in Returns. Legit FTL traveling speed(Red Hood n' the outlaws) Increased mind capabilities and processing(reading every medical textbook in history to perform Lois's surgery) Blitzing Orion. Flicking major force with a finger. Lifting Earth for 5 days straight without access to his power source. Surviving in the sun while being weakened from red sun radiation. Tagging Barry Allen and effortlesly breaking Hal's constructs. Punching with mountain level strength. These are what first came to mind. There are many others.
It is very clear New 52 Superman is in the same ballpark as his pre-flashpoint counterpart. He obviously lacks the quantity of feats, but the quality is there.
