TL,DR: Most games make me sick/uncomfortable when I play them. I would really like to know the source of this.

I don't really notice FPS very much if at all. If the game is still going smoothly low FPS isn't a problem for me. I played games where the FPS was extremely low and the game still played and looked smooth. I have played other games that get 10 times the FPS and they aren't playable. The frames are there the game just isn't doing much of anything during them, or the it seems to control choppy. Not absolutely certain. I am suspect though that many of the video cards I have owned far out performed the rest of the parts in the PC.
I can remember back when I was playing Borderlands on a PC with a 2GHz single core CPU, 2GB of RAM, and a ATI Radeon HD 2400 PCI card for graphics. It ran fine. The only time it even was noticeable slow was when things like the skag spitters were covering me in liquid globs. I never had any problems with that game. I now have a 3.2GZ dual core, 8GB of RAM, and a ATI Radeon HD 7750 PCIe card. When I play borderlands 2 with it I get a extremely sick uncomfortable feeling that totally has ruined the game for me. I've managed to log over four hundred hours in that game even so. My little brother really loves that series and was always trying to get me to play. He has well over a 1,000 hours in Borderlands 2. Most of that he had to play by himself, and I couldn't put words to why.
I am not for sure if it is the FPS, resolution, FOV, or what. I just know I get a sick feeling when playing many games and it has driven me away from them. It has actually almost entirely driven me away from gaming altogether. I rarely if ever get that feeling when playing Minecraft though. The fps rarely goes above 40 and that high is usually a spike, The FOV is set at default. It is in windowed mode and maximized to fit most of a 1920*1080 Resolution screen. It just doesn't cover the task bar. I found this is a game I must multitask in. Alt-Tabbing just doesn't work for me. So I have it set up like this so I can easily switch out of it.
I still think FRAPS frame counter wasn't working in Runes of Magic back when I was playing it. FRAPS stated I was only getting 1 FPS. It never dropped. It never got higher. Yet the game was running extremely smoothly.
