I agree with H-Street. Turn off the swaying in the game configuration menus. You'll find it under Setup->Options->View Swaying
. Make sure it's off, then try the game again. If you are still having problems, try setting the default movement to Walk
to slow things down a bit.
The only game I ever had a problem with was the original Wolfenstein 3D...because I checked every damned wall for secrets...and I blame that for messing up my right eye... Used to make me dizzy.
