VR samples working in Oculus specs?

A question here. I haven’t got a GTX970 and was wondering if anybody has try any Epic sample of that hardware and how good is the performance. Are there any sample from Epic that works fine in that hardware nailing 75fps in DK2. This is not enough to warrant 90fps in CV1 but at least is a first test for a sample.

My intention is to have a good VR sample to use as a guide for good practices. Do not know if Epic has released a sample with this purpose in mind.
