Today I took one of the levels of InFlux that I revamped for the UE4 Marketplace and, using Teddy's rollercoaster plugin, added a rollercoaster. Here it is, yo.
It's basically the same exact thing as the Rift Coaster you've all played except it's in some cool lava-filled caves. It might have higher system requirements, not sure.

Hi, this looks nice and was looking forward to giving it a try, but am getting a crash at startup (after picking quality levels). Here's the callstack dump:

Well gave it a go and it looked nice and was smooth but for some reason I found it very very dark and for large parts of the ride I could not really see where I was going unless there was lava around to give it some light.

Hmm, no idea about the crash error, but I'll look into it. Tried the obvious stuff like restarting?

@razalom: I actually know what this is, it seems to be a bug with UE4. Basically, if Post Process is on Low or Medium, the exposure gets set way too low. If you set post process to High or Epic it should solve that problem entirely.

OK cheers Joewa will give that a go later

Hey Joewa, I just gave this one a try, but I get exactly 37.5 fps in Direct Mode and between 45 and 60 fps in Extended mode. When running the UE4 Rollercoaster I get 75 fps.

By any chance, did you compile it using the the latest 0.4.3 Oculus runtime? I believe that they introduced a bug which affects UE4, can you please try recompiling it using the previous 0.4.2 runtime?
