Nvidia & AMD Driver Optimisations For Rift Users
I've created threads in the Nvidia & AMD driver forums politely requesting their devs to look into driver optimisations specific to Rift users:

Please feel free to jump over to either/both threads and add your support to the cause, they'll do it if there's enough demand from us users :)
They highlight three areas where I can see large performance and usability improvements can be gained:

They highlight three areas where I can see large performance and usability improvements can be gained:
- Duplicate data being rendered for both halves (left & right eyes) of the display
- Detail levels outside of the eyes' visible area (see linked example image below, from VorpX)
- SLI/CrossFire tweaks to reduce latency

- There's probably not a great deal more (if anything) they can do to reduce SLI/CrossFire latency - that will already have been undertaken for non-rift users as minimal latency is essential for all gamers.
- You might be interested in Nvidia's Maxwell launch slides. One of them is entitled "VR DIRECT" and summarizes VR specific optimizations:
* Low Latency
* VR SLI
* VR DSR
* MSAA
* Auto Asynchronous [Time]Warp
* Auto Stereo
I assume AMD will respond soon.
