To be clear from the beginning, this is not a problem. This is just something that I really want to know the secret behind.
- CPU: AMD A10-6790K 4.0 GHz
- GPU: AMD Radeon HD 8670D 1 GB (integrated GPU)
- RAM: 2 x Team 4 GB 1600 DDR3 = 8 GB
Of course, I'm using a 64-bit OS to make use of my 8 GB of memory, but my question is: Before I got the additional 4 GB RAM, games like Mafia II ran at the highest settings at an average of 22 FPS, but when I got the additional 4 GB RAM, I noticed a very decent increase of the frame rate to 40 FPS even though the game didn't appear to use more than 4 GB of RAM.
What is the secret behind this?
