VR rendering needs a lot of GPU power. VR SLI can help that. But, is it possible for us to use distributed parallel rendering technology to improve the performance dramatically? There is an open source software "equalizer" which could do that.
For example, put 4 or 8 GPUs in one PC server and disable vender's SLI driver. Use equalizer to do parallel rendering. Or, run equalizer on 16 PC servers with GPU equipped.
So that we can get very high performance easily? Right?
Equalizer supports sort-first and sort-last. Since sort-last needs a lot of network bandwidth, we'd better use sort-first.
