This is a point I never considered, thanks for sharing. Accessibility is important. Makes me want exhibit my games using CRTs for the ideal experience. This discussion has me thinking about the divide between VR players that experience motion sickness and the ways games try and don't try to fix this.
It might be unrealistic to exhibit games on CRTs if they aren't going to be played on CRTs - if you've got a lot of headroom with the 30fps target, is it worth trying a subtle CRT emulation shader? Especially with people frequently having 120fps+ monitors, it seems like a subtle fadeoff could be made to work.
P.S. I thought your original question was madness, but now that you've posted your projects I can totally see why you're targeting lower framerates. I really like the mood, have wishlisted TO:RI
