I ask this because when my eldest son comes to visit and fancies a gaming session, he complains that the game (usually modern 3) seems to run too fast or is too smooth. I own a Samsung 55D6530 and use the game setting while gaming but this makes his eyes feel strained and tired and at worse can make him feel sick or give him a head ache but doesn't effect me the same way or could it be something too do with the screen refresh rate. I really don't know why it effects him like this.

Samsung TVs are active 3D TVs and I'm assuming your son is playing a 3D game. Active 3D glasses use flickering technology, that is, one glass will see an image while another one is blacking out and vice versa so that the image is seen by one eye only. Active 3D glasses therefore can cause a little headache depending on how many images they can show per second for each eye. Eyes of your son can get tired very easily if he's not fit for that technology. I myself watched a movie on Samsung one day and I felt the flickering from beginning and this flickering was very uncomfortable that I actually had to stop watching it. I would recommend you buying a passive 3d TV. LG is the leading passive 3D TV and it is very good for playing 3d games and watching 3d movies.

It has nothing to do with your refresh rate. As Richard stated, your son seems to play it with 3D because Samsung uses active 3D technology which can strain the eyes. Active flashes two different images to your eyes so quickly so that your brain thinks you are watching the screen 3D, which is fine but that causes flickering. Flickering is not something that you can avoid if you already bought active 3D tv. My advice is to keep the glasses' battery always fresh since flickering bets worse with low power and make sure your son plays with it no longer than an hour.

Xx (for short) doesn't say his son was playing in 3D, which would have been an essential piece of information if he was. Is he used to playing on a 55 inch screen? If not, his eyes will be darting around all over the place whilst playing which will cause him to feel sick after a while. He would be better off playing on a smaller screen, around 32" in my opinion. If by chance he was playing in 3D, to avoid flicker from active glasses you have to be well away from a light source (eg windows) and so ideally the curtains should be drawn during the daytime.

When you use Game Mode on a Samsung the DNIe chip in the TV is bypassed, so the incoming video is not being processed by the TV, allowing for a faster video response time (Higher screen refresh rate) which would explain why it looks "too smooth" I would simply turn game mode off when he is playing, especially if it is giving him headaches.

you don't want processing. processing = lag, a few frames of lag undermines gameplay.
