Get nauseated, headachy after playing game, anyone else?

I know this sound weird, but it happened 3 separate times after playing Penumbra on my PC today.
Is it just me? Coincidence? Something else going on?
Anyone else experienced this?
Caused by a "flicker" of the screen I can’t perceive?
Never ever had this happen before. Told you it is weird, any thoughts?
BTW: Just started playing the game today, have GREAT fun so far with the exception of this “situation”. :cry:

This can be caused by many things:
• do you have general motion sickness?
• view bobbing can aggravate this (I don't think it can be turned off)
• are you playing in a high contrast environment? (try playing in a well-lit area)
• are you playing with no crosshairs? (enable crosshair so your eyes have a "resting place")
• if you are using a CRT, ensure your refresh rate is at least 85Hz.

You may also wish to try turning the noise filter off. It makes a little static film over the display. Your framerate may also be low, so try lowering graphics settings and the game may play more smoothly.

Thank you for your replies, thought maybe it was just me!
Will try your suggestions (if I can figure out how!) and get back soon.

I have similar problem with Penumbra series. That static green glow from the Glowstick is causing me headache when I am playing in dark room.

• are you playing with no crosshairs? (enable crosshair so your eyes have a "resting place")

I will gonna try that. It sounds promissing.
