The knowns and unknowns of virtual reality

  

There are many phrases and concepts that have entered our subconscious via pop culture. One of my all-time favorites has to be the idea of knowns and unknowns commonly used inside NASA to outline the degree of uncertainty in safety-critical missions. Known unknowns result from phenomena which are recognized, but poorly understood. On the other […]

Identifying GPU bottlenecks using PVRTrace in Fantasy Warrior 3D (7)

Identifying GPU bottlenecks using PVRTrace in Fantasy Warrior 3D

   

In my previous post, we explained how to use the advanced features of PVRTune to find the specific causes of performance bottlenecks in the Fantasy Warrior 3D game built using the Cocos2d-x game engine. In this post we will demonstrate how developers can use PVRTrace to locate GPU-related issues in this Cocos2d-x based game. We […]

PowerVR Ray Tracing - Hybrid rendering in Unity 5 (1)

Go from zero to hero in one day with Unity 5 plus hybrid rendering

   

The focus of this posting is to show Unity artists how easy it can be to add true reflections and shadows to their content using our hybrid rendering techniques. The PowerVR OverDrive game runs live, rendering with a PowerVR ray tracing GPU installed in a Linux-powered computer. Using an Xbox 360 controller, you drive around […]

Dwarf Hall: physically based rendering on a PowerVR GPU

    

Physically based rendering (PBR) is becoming more prevalent on mobile class GPUs. In this blog post I will give a quick overview of what PBR is, what the advantages and disadvantages of using it are, and some tips on how to use PBR and deferred rendering when running on a PowerVR GPU. I’ll also show […]

Advanced performance analysis on Fantasy Warrior 3D using PVRTune (1)

Advanced performance analysis on Fantasy Warrior 3D using PVRTune

    

In my last blog post, I explained how the timing data and high-level counters in our PVRTune GPU performance recording tool enabled us to identify that the Fantasy Warrior 3D demo was CPU limited when running on our PowerVR-based target device. In this article, we will describe some of the advanced profiling counters provided by […]

Tiling positive or how Vulkan maps to PowerVR GPUs

    

Welcome to the last blog post in the series! You might notice that it’s a bit late – this has been sitting mostly complete on my account for months, but with the Vulkan release taking up a lot of my time, I’m afraid it got neglected! Well, finally we’ll be looking at why Vulkan is a better fit to hardware than previous […]
