Anonymous: <p>While we can see that TRON already has unequaled Video Warrior/Combat capability in the original movie, but in a hypothetical scenario where he had to push himself harder than normal during a Game Grid game, would be able to overclock himself? And would his Circuit color flare brighter in the process?</p>

Hmm, I imagine so! Any program can be pushed to the limit where it crashes, and even Tron would have his limits

Not sure what that would look like inside the Encom world, but yeah, things like that do tend to be expressed with changes in circuit brightness. I do love the variety of different ways the movie shows that!
