We recently hooked up with overclocking guru Sami Mäkinen to get his take on the best way to overclock AMD's A8-3870K APU.

So, if you increase the reference clock, you pretty much overclock everything.

NVIDIA Announces a Fallout 4 Mod

by Scott Michaud |
It is designed to show off GameWorks technologies, such as volumetric lighting and HBAO+, more heavily than Bethesda did with the base game.
If you're wondering why NVIDIA has a game development studio, they are mostly responsible for bringing content from the PC to their Shield devices, such as Half-Life 2 and Portal.

A New Perspective on Multi-GPU Memory Management

by Scott Michaud |
AFR is very balanced for multiple, identical GPUs, and it's easy to implement; unfortunately, it could also introduce latency and stutter, and it is inefficient with video memory.
Layer-based methods, on the other hand, are complicated to implement, especially for objects that mutually overlap, but it allows for more control in how tasks and memory are divided.
The tiny details of the environments being rendered will have to increase, as people will physically walk up to the walls, chairs, doors, windows and look at every single little bit with excruciating detail.
I replied saying that the personalization era has been here for a while with gamers - who will spend hours customizing their in-game character or buying hats in Team Fortress 2 or skins for their guns in CS: GO.
GIGABYTE has completely surprised me with their efforts on the GeForce GTX 1080 G1 Gaming card, and what's possible with some excellent engineering, cooling technology, and a single 8-pin PCIe power connector.
It's great, as the GTX 1080 G1 Gaming didn't need any additional fan speed increase to handle the additional load from the overclocking.
