Since the Core i3 3220 has Hyper-Threading, will games like Battlefield 3 see and use the CPU as a virtual "quad core" rather than just 2 physical cores, so that AI and other features in the game run more efficiently?

Quick answer: they will use the four "logical" cores.

A program typically scales to multiple cores by running multiple concurrent "threads". The underlying OS typically manages which threads run where (called "scheduling"). If the OS sees 4 cores (and with hyper-threading, it will) - then four threads will run in parallel.

The game may have a variable number of threads, by asking the OS about the available number of cores. If this is the case, the game will most likely see four cores.
