Why does capped 30 fps feel so Bad On New Computer?

I was playing Just Cause 2 on my new computer (which I built) at a steady 60 fps unless I flew over the city in which it dropped to 40-50 frames. I was interested how much better it would feel if it was capped at 30 fps. I quickly realized that 30 fps felt unplayable, even when I wasn't moving the mouse it felt a bit jaggy. I could pick out the individual frames.

Just to make sure it wasn't Just Cause 2 I tried capping the fps on Counter strike source to 30 fps and again it felt very jaggy. I also had to turn on v-sync to stop the bit of screen tear (at 30fps).

I have already downloaded the latest drivers for my R9 270x (14.9). I have never minded 30 fps before when I have been playing on a Wii U which was connected to a tv. I wouldn't even mind if the frame rate dropped a bit. So why can't I stand 30 fps on my computer? Is it a hardware problem or is it just me used to 60 now? It is something to do with it being capped as 30 fps felt ok on my old computer which had integrated graphics. Would needing v-sync at 30 fps also signify a problem?

Thanks for any help.

There is a multiple aspects of this topic such as refresh rate, fps, input lag, artifacts, etc so the answer isn't that simple.
People who claim they feel no difference between 30 and 60 fps are either not trained enough to see it or are smoking to much weed so they have all visuals blurry.
People who compare ingame fps to movies are unaware of motion blur which makes video look more fluid, while game frames are crispy, so you can distinct more precisely that something is wrong.

Vsync is even more complicated topic. People who say "DONT USE VSYNC IT CAPPS THE FRAMES" probably don't get it at all. First of all VSYNC indeed caps frame rate but for to make drawing artifacts less...

your old pc was probally running at a lower resolution thus less lagg thus smoother if your new system cant run everything on max set the settings lower DONT USE VSYNC IT CAPPS THE FRAMES better off with V sync off

It probably just feels bad because you've been playing the same game at 60fps. We've been watching youtube videos at 30 fps, now they're allowing 48 and 60. Once you get used to those the old 30 fps videos are going to look like crap.

YouTube videos at 30 fps never looked bad to me though, not even when I have just been playing a game at 60 fps. I assume thats because they have motion blur applied to them. If they don't how come 30 fps feels bad in game?

Vsync is even more complicated topic. People who say "DONT USE VSYNC IT CAPPS THE FRAMES" probably don't get it at all. First of all VSYNC indeed caps frame rate but for to make drawing artifacts less visible, it obviously also limits GPU usage which leads to less power draw and cooler GPU.
It is personal preference, some people say they still can feel difference above 60 fps, while i feel its more placebo effect, cant see a reason to pull GPU more power then it should for the same effect.
If the majority of time a game is bellow 60fps (or other native monitor refresh rate) there is no use of it... or probably it makes things even worse since it requires some resources itself.

So answering your question... you tested it on typical fast action games where screen draws totally different frames very frequently thus you can distinct that changes more often. If you run 30fps at Pro Evolution Soccer you wont notice anything like that. On the other hand try turning off vsync at PES you will see how jaggy it is due to unsynchronized frames.
