The ASUS ROG Swift PG278Q 27-in WQHD display with a 144 Hz refresh rate is truly an awesome monitor.

We see a move from 64-bit wide LPDDR3 to 64-bit wide LPDDR4 on the memory interface, which improves peak memory bandwidth from 14.9 GB/s to 25.6 GB/s and improves power efficiency by around 40.

NVIDIA Publishes DirectX 12 Tips for Developers

by Scott Michaud |
Drivers would play around with queuing them and manipulating them, to optimize how these orders are sent to the graphics device, but the game developer had no control over that.
Pretty much all of them apply equally, regardless of graphics vendor, but there are a few NVIDIA-specific comments, particularly the ones about NvAPI at the end and a few labeled notes in the “Root Signatures” category.
This is easily our favorite tool for overclocking and GPU monitoring, so it's great to see the company continuing to push forward with features and capability.
It means as DX12 applications that find their way out to consumers and media, we will now have a tool that can help measure performance and monitor GPU speeds and feeds via the PrecisionX overlay.

GDC 15: PhysX Is Now Shared Source to UE4 Developers

by Scott Michaud |
This means that you can make legitimately free (no price, no ads, no subscription, no microtransactions, no Skylander figurines, etc.) game in UE4 for free now!
NVIDIA and Epic Games have just announced that Unreal Engine 4 developers can view and modify the source of PhysX.

Most DirectX 12 features won’t require a new graphics card

by Ryan Whitwam |
While past updates to DirectX have focused on new rendering effects like tessellation and more realistic shaders, DirectX 12 is an attempt to dramatically reduce driver overhead and get PC gaming closer to console levels of efficiency by learning some lessons from AMD’s Mantle API.
Consoles have very narrow hardware profiles, but the hardware abstraction layer in DirectX slows things down.
