Public parking is all pretty much metered. There are a number of pay lots
East campus parking deck
Intramural fields. Bus ride to stadium and back. Can walk it in 35 to 40 min.
I park downtown and walk through campus - ring the chapel bell on the way back (After A Win)

Never had a problem getting in or out of the east campus lots and there are busses running to and from the stadium
Intramural lot is free parking. Exit the Loop at College Station, hang a left. Fields will be on the left. Long walk to the stadium, so wear comfy shoes.
There are plenty of Pay to Park lots. I generally park in the lot next to the hotel Indigo. It's $$$$ though. But it is a straight easy walk to the stadium.
Where ever you can find a spot. Lots of pay lots around. Price goes up of course as you get closer to the stadium.
Good luck,is all I can say
