There’s an even smaller difference in this game:
We can see the effect from our memory overclocking at nearly any settings:
The maximum performance gain is 6.3% at 2560x1440 with antialiasing, yet it only means an additional 2 fps.
Tomb Raider (2013)
The performance benefits are smaller here:
The extra 1GHz of memory frequency means a 1.1 to 4.3% increase in frame rate.
BioShock Infinite doesn’t speed up much after our memory overclocking.
Metro: Last Light
This game is more responsive to the higher memory frequency both with Advanced PhysX enabled...
…and with Advanced PhysX disabled.
The maximum performance gain can be seen at 2560x1440 with antialiasing. It amounts to 5.9%.
