More Ray Tracing GPU news from MWC 2016

First off I am posting this in the desktop GPU section as the videos are run on a PCI express GPU in a desktop and the tech is designed for mobile and desktops.

Ray tracing, the walking dead and monster trucks at MWC 2016

Wow pretty soon we'll have playable cutscenes from 1994.

Not sure I understand what you mean and I think you might have missed the point of those demos. The ray Tracing bits are amazing.

“So having an environment reflect off car paint is nothing new, which also begs the question: just how much Ray Tracing is demonstrated here?”

All the reflections, lights and shadows are ray traced. No special assets or programming was done for the shadows and reflections which was the point of the demo. I agree the none ray traced parts of the demo are not that great but the demo was to show how ray tracing can simplify content creation for developers while saving memory bandwidth, memory & giving a speed increase all for better quality lights and shadows.

What benefit does probe texture overlays have for gamers over the current way?

There are a number of benefits depending on how it’s used. At the moment the most common benefit is for developers to use it to simplify content creation. This means the developers can spend a lot less time on getting the shadows, lights, refractions how they want and spend more time on other parts of the game. Or parts of the game they just wouldn’t have had time or money to do good shadows, lights, refractions can now have that applied for very little work. In short a developer no longer needs to spend anywhere near as much time or money on a team artists doing lots of lights and reflections all over the map. Ray Tracing does all that automatically for you.

The other benefit is if you have Ray Tracing hardware in your device and the game supports it you get a performance boost with better quality lights, shadows, refractions and better power usage. Ray Tracing is far better suited to do certain effects and you an do those effects in Ray Tracing for far less compute power then the more common ways of running games.

I would prefer people to start adding 3D environment based sound with first order reflections and diffractions before ray tracing light sources. The sound in games is so bland and unrealistic now days.

Sound plays just as big if not a bigger part of the immersion compared to graphics.

That I fully agree with sound has taken a giant step backwards in the past years.

For you Pottsey.

Some Real Time Ray Tracing on my GTX 970.

Thank you. It’s a fun little hybrid ray tracing demo that show the possible potential of Ray tracing but it has its flaws. I could never get anything but a tiny amount of the screen in focus. Everything outside the tiny section is blurred. Someone please correct me if there is a way around the blur but as far as I can see they only ray tracing a tiny part of the screen then blur everything else out. It’s a nice trick but not that practical. EDIT: Looks like the blur can be removed with the insert key. Nice will have to have a better look tomorrow.

Still it shows the benefits of hybrid ray tracing which I believe is the way forward over full ray tracing.

Don’t think I posted this one. https://www.youtube.com/watch?v=uxE2SYDHFtQ my complaint about this one is the lack of motion. All the light sources and objects are too static. Very nice background lighting but can it hold up with motion?
