Feeling sick while playing Portal 2

Change FOV

When I was young one a game called Descent made me feel sick once or two, but never with Portal 2

I have never had any problems with default fov in any game...

Only time i felt motion sickness was on trauma level of hotline miami.

I never have any problem with any game.. but Metro 2033 gave me sickness

Only when I get very low FPS in any game.

Same here, I've also had something similar with Prey.

maybe turn up the FOV?

I felt sick playing it through the first time. weird. thought it was just me.

I only experience it with games, which are optimized for consoles.
Something about the fixed framerate, different mouse feel or style of graphics is confusing my mind :S

you just can't stand it's awesomeness of awesome!

I have it too when I play portal 2. Sadly I can't handle first person games that great...

Too much brain usage?

Motion/Simulator sickness. Me too. :(

I get it from COD: Black Ops cutscenes. Feels like they want me to go into an epileptic fit all the time...=.=

i feel sick on some fps games too, vertical sync helps, and maybe some 10min playthrough will help to get used to the movement.

also, keep your eyes on the portal gun at all times, it helps

that's because the game's just sick!

I had it with portal 1, but I felt fine on portal 2. They fixed a few issues I personally had when it comes to motion sickness.

The only game that gave me serious motion sickness was MechWarrior 4: Mercenaries.
