I made these with our upcoming Octane Render 2.2 version, after some forum users asked for videos of the performance of the GTX480. These are live filmed footage (with a cheap pocket digital camera unfortunately) of me driving octane on a PC with:
2x GTX480 in multi-gpu mode (Asus EN GTX480 stock clock speed, both in PCI-E x16 slots on an Asus WS motherboard) CPU: Core2 Quad i7 920 6GB RAM Thermaltake 850 Watt PSU Windows 7 x64
device manager setup image:
The model is just over 4 million triangles and there are several large texture maps hooked up as diffuse, specular and bump maps. In total it consumes about 1GB of video memory. (the memory indicators are broken as we haven't yet hooked them up in the new multi-gpu engine)
The way the multi-gpu rendering works in octane is that the navigation is faster, not the noise is less and the framerate stays the same, so if you were to have 4 GPUs it would navigate another 2x times faster.
All rendering, eg images and videos, is done at 1280 x 720 resolution with always 2x GTX480. (display used is 1920x1080 resolution) No subsampling was used, it's per pixel rendered.
EDIT: Here's the new video that philbo made of all the videos with audio/music on youtube, it's really cool:
Here is a video of navigation with directlighting (default settings):
The footage is real-time filmed. These are large AVI files straight off the digital camera, can someone who knows about these things upload them to youtube or vimeo and post links here ? (i've never used those things and don't have a clue how to start nor a login on them)
We've also made some more optimizations and also optimizations for fermi cards, so the GTX480 is a real nice card for octane. Even with one of these you'll have a pretty similar experience. I would highly recommend professional users of octane render to get 2 GTX480 cards, especially if you want to do interactive demos of your models/architecture for customers.
Wow, really impressive video's Radiance! Awesome, thanks a lot! The directlighting vids are particularly great. And OpenGL rendering is indeed slower than raytracing, must be a first I can't hardly imagine what Octane will run like on GPUs from 2011, you might want to make a virtual reality engine by then
