[PC] I found this old thread, and thought I’d add to it. I believe the motion-sickness issue should be a high priority for the devs.
Some of the nausea in my case is due to the motion blur, which can be deactivated using the settings. But the bobbing/swaying of the camera is still an issue (cl_bob 0 and cl_headbob 0 did nothing), and I still get motion sickness - the effect of your body reacting to one thing and your eyes experiencing another, which confuses your senses. Truth be told, I’m a Navy vet, and I hadn’t felt this sick since I traversed the North Atlantic.
I would highly recommend that the option to turn off these features be presented to players at the very beginning of the game, after they play a few minutes in the prologue. I believe the nausea-issue is prevalent, and that these features heavily detract from an otherwise excellent game - far more than any “bug”. Or rather, the difficulty for new players to turn these features off…
