Tomb Raider
We start this benchmark off at the 7% mark right after leaving the campfire. In this run there is a good variety of environment changes from out in the open on some cliffs, to a cave, to burning buildings. There are some stealth kills, and bow kills, as well as a semi-scripted climbing scene.
With an average frame rate increase of 9 frames per second, Tomb Raider definitely enjoys the added throughput that overclocking enables. Minimum FPS is up by 6, and Max is up by 5. Not dramatic increases, but still enough to keep the game above 45fps at all times.
