My rift is due to arrive tomorrow. I had a dabble on monitor today but finding the gokarts a bit of a chore, getting motion sick on my monitor. Not sure if will be better or worse I vr.
Afaik all versions use the rift skd so you will get the same experience on steam as on oculus store
Whilst there are a few games which test me in vr motion sickness is not something I am used to on a screen
i find motion sickness is a problem with the go-karts. i put it down to lack of cockpit meaning everything in your entire vision is moving(similar effect to the SRV with its wide cockpit windows).
maybe if you could force the helmet cam on in vr it might help.
