That's disappointing. I know that I used to get motion sickness with FPS a lot, but I was kind of forced to play them when RPGs and platformers died off on consoles so maybe I got a little bit better with it. Some games I can't play in VR and I never attempted to go back, like Doom VFR, but once I got more used to it I moved onto other games. Resident Evil 7 is just such an amazing experience that is just unparalleled when played in VR compared to just playing the game standard. I've only played Resident Evil 7 with the 35 degree turning angles though, basically the game does a complete turn of 35 degrees, in a single frame of motion instead of seemlessly turning and that is effective at reducing the effect of motion sickness as well.

I'd say look into what games you have that might have 35 degree turning and try those as well, maybe those might assist. Oh, and if you own Skyrim, whatever you do, DO NOT JUMP OFF A HIGH AREA. Holy fu**. I get motion sickness in jumping off a high area in Monster Hunter World without VR, but when I did that with Skyrim VR, I immediately had to take off the headset and go lay down.
