To be clear from the beginning, this is not a problem. This is just something that I really want to know the secret behind.
System specifications
- 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?
3RAM adds capacity, not performance. if you didn't have enough, then you had run out of capacity. The upgrade provided the additional capacity you needed to run the application more efficiently. Also note that modern systems will do lots of things that slow you down (swapping and non-cached IO for instance) before they will let themselves use all their ram, so even if you are not yet using all your ram, you may have used all the OS will allow for your specific process. – Frank Thomas – 2014-07-29T20:01:03.850
