Me too. The problem is always of technical nature, and, unfortunately, not all game developers are aware of the problem. When resolution, frame rate and FOV are just right, there is no motion sickness to speak of. That's why some games play perfectly fine while others give motion sickness. It all depends on your monitor, your GPU, your sitting position, and so on. Some games have good motion blur that helps (if the frame rate is consistent), while others have a horrible motion blur that would make me sick. So, tweaking all of those parameters, sometimes being forced to use external tools (like nVidia inspector) is the only way to go. With some games, even after all that tweaking, I still can't play comfortably. So it's a hit and miss. Third person games have the same problem albeit with much smaller nausea potential. Here's what you can do: try another monitor/TV, try different sitting position, try limiting the frame rate, try adjusting/hacking FOV, try turning on and off motion blur, aberrations and similar post processing options. Good luck!
