So, i ran into the same problem of every game i try crashing with vireio. I got Win 8.1 64bit, 4GB Ram, Radeon HD 7660D - Most VR things run okay with (for some people seriously horrible) 30FPS. When i launch Games and my Oculus is in Direct Access mode, the games show up fine in stereoscopic view on my monitor and tracking works all fine. When my oculus though is set to Extend to HMD Mode, any game Crashes as soon as the Green text appears on screen.
As suggested, i changed the directory of my Perception to C:/Perception (so no more spaces). Since They still crashed after that, here the tracespy log:
