AMD & NVIDIA GPU VR Performance: Google's Tilt Brush

We are changing gears a bit with our VR Performance coverage and looking at an application that is not as GPU-intensive as those we have looked at in the recent past. Google's Tilt Brush is a virtual reality application that makes use of the HTC Vive head mounted display and its motion controllers to allow you to paint in 3D space.

What is Google's Tilt Brush?

Tilt Brush is a VR application developed by Google for the HTC Vive VR system. Our focus today is to use this very popular less GPU-intensive title to find out if the scaling we have seen in other VR applications and gaming remains static.

Here is what Google has to say about Tilt Brush:

Painting from a new perspective - Tilt Brush lets you paint in 3D space with virtual reality. Your room is your canvas. Your palette is your imagination. The possibilities are endless.

Instead of droning on about it, it is likely best that we just show you what Tilt Brush is all about if you have never seen it in action.

As you can see the software is fairly straight forward as to what it does. I was using this last week in the office and got my kids involved. Watching them create inside Tilt Brush was an entertaining experience, and I got to thinking about what kind of GPU usage was involved.

Tilt Brush uses the Unity Engine so I figured it would be a good application to see if the GPU scaling that we have seen in GPU-intensive games is "the same." Most of the art we have seen is not close to photo-realistic, some of it can be very busy to say the least.

While you cannot animate the scenes you create, they do actually have certain brushstrokes that are animated to some extent. Some of the brushstrokes actually pulse and move to the music you have playing if you wish so.
