45 fps or 90fps on oculus rift ??

In rF2 I use 90 fps with ASW automatically switching it down to 45 when the graphics load is too high (the default for Rift). For ACC it's apparently better to give up trying and instead fix it at 45 though I haven't got ACC to work well in VR. I think it depends on how powerful your system is and how high you set the graphics, 90 fps is better as long as it's consistent.
