That could do things like the image distortion and colour aberration correction in hardware, without the application needing to be aware of it all. The application feeds it a regular side-by-side or frame sequential signal and the FPGA would do all the work that currently has to be hacked in through shaders or the late image warping used by Rift for reducing the tracking latency. Basically that would make integration of such HMD very trivial, not requiring specific support from Nvidia or a proprietary SDK where you are at the mercy of the driver vendor because everything is done by your PC. 


This is a good idea, provided that you are able to send the HMD an image with higher resolution then the native resolution of the display. Otherwise the warping inside the FPGA will have too few pixels to work with.
