This is like a worst-case scenario for YouTube's compression algorithms, so it's hard to say how this would actually look on your screen. Rather than seeing the noise you just see the macroblocks even at highest resolution.

There's a better quality video on their site here: http://brigade3.com/brigade-3-0-preview-at-gtc-2014 http://brigade3.com/brigade-3-0-preview-at-gtc-2014 I've been playing with OctaneRender and LuxRender but hadn't heard of this one before. Looks good, possibly faster than Octane judging by the video, but it's impossible to know what they are running it on. I'm very hopeful that incremental improvements to path tracing algorithms over the next couple of years will reduce the amount of noise in real-time, as the render quality is amazing. However even on a high end machine, with a complex scene you end up with a lot of black areas, which makes everything look darker. LuxRender partially solves this by rendering over the top of the last frame by default, but that sometimes creates some nasty ghosting effects that can be worse than always painting over black like Octane does. If you want to try this stuff out there's a free demo version of Octane you can download and LuxRender is entirely free. However Octane requires a CUDA card with a fair bit of VRAM as it does everything in GPU and the size of the scene is limited by the amount of VRAM you have. LuxRender is currently only stable in CPU-only mode and doesn't come with any UI to speak of; it's more of a rendering toolkit. You can't just open it up and move a scene around in real-time. You can do that with Octane though and I thoroughly recommend giving it a try. There seem to be a fairly significant diminishing returns over rendering time with path tracing, so the results you get in real-time will probably be about the same on a wide variety of cards, i.e., full of noise and black areas, but still impressive. The difference between a render running for 4 hours vs one running for 8 hours is far less significant than the difference between 10 seconds compared to a minute. Edit: I just noticed that Brigade is from Otoy, who own Octane Render. The site's not particularly clear about it, but it looks like this is their cloud-based render farm solution based on Octane. There's an earlier video somewhere showing real-time movie-quality rendering over something like 144 GPUs (instead of the 2-4 in this video). However the cost for renting that much GPU power was pretty astronomical.

  I would buy 4 of whatever replaces the Titan Z if I could play a game that uses this tech at 3x 4k 120hz. That is absolutely beautiful for realtime.
