A counter point to AMD not being good for mid-high end - Page 34

post #331 of 355
Good job showing the results of a GPU bottleneck. That's a move right out of the AMD marketing handbook labeled "how to sell opterons to gamers."

Thats a real amd bottleneck there....lol
post #334 of 355
I use my 8320 4.5 ghz with 2x r9 290 trix on a 120hz monitor and i don't see any bottleneck, my eyes are not powerfull enouth to see the difference between 110 and 120 hz .

There certainly is a bottleneck otherwise you wouldn't see the performance gains demonstrated via Mantle.

Perceiving the difference between 110-120, well I'm right there with you on that smile.gif

You are right about mantle i wish there will be more games to use it considering dx12 is far far away ( and i don't think it will be that much of an improvement)

I keep getting flak from people when I say that there is a limit to which our brains can sense motion. The limit is ~60 FPS. Now, we do not see in FPS, but the studies have been done by psychologists (which I hold a psychology degree, just a B.A. but I helped my professors write some academic papers about how our cognitive functions react to the environment). When it comes to getting 120Hz monitors, the cost far outweighs the benefit. If you are buying the Hz thinking that those will give you 120 FPS, then the better way to spend money is to blend it together and make a liquid-like substance, drink that, and then like Carter Pewterschmidt, pee away the money in about 20 minutes.

And yes, like I said earlier, they have done the studies. They would have about 5 side by side displays. 1 of them had a movie (24 FPS), the next one had a movie (48 FPS), another one had a recording (30 FPS) another had a recording (60 FPS) and the last one had a recording (75 FPS). Now, I am going by memory because the study, which was not as much a study but a demonstration, showed that after the 48 FPS video, people were not able to tell the 60 FPS video from the 75 FPS video unless both were slowed down to half speed.

I guess the point I am trying to make is that if my CPU does not bottleneck my GPU, then I am going to buy the cheapest one I can find that is about 1 year's worth of future proof-ness if you know what I mean. A GPU only needs to make a display have 60 FPS for it to look smooth. I never understood why people want over that other than for bragging rights. 2 780 TIs in SLI is the absolute max of the sanity/performance ratio.

EDIT: And the frustrating thing is that I cannot find any of this stuff on Google Scholar which is an academic research paper site that would have this study. It was done at my university but I do not know if it was published or if it was just a demonstration like I said. I wasn't interested enough to participate so I do not have all of the facts, but it makes sense because of neural activity in the brain and the fact that we must become consciously aware of movement in order to tell if something is moving, ect. ect. I do not want to bore anyone. So I hope you guys will just take my word for it because I have no proof and no source and that is a hard thing to convince people of, especially people who are into getting good frames in video games.

The problem with this study is that they use a movie. On a gaming situation especially with fps games the difference between 60hz,120hz,and 120hz lightboost is huge. And no the limit is not 60 fps for the human brain because human brain can adapt. Anything over 25 fps and the human brain get it like a motion. We dont know the limit

The easiest test is to use an anime video with SVP on and off.

Makes sense and the movies were not able to show very fast motion. But I think the problem here would be motion blur. There is a big difference between 120 Hz and 60 Hz when it comes to motion blur, but if I were getting a monitor, there is no way I would pay more for a 120 Hz monitor. I am speaking based on what I learned about video motion. My education has a limit, and I learned about how we process motion from my time working with professors as a lab assistant. Motion in which you are actively participating may be different than the type of motion that I was taught about. Passive viewing is one thing, but actively moving the mouse and concentrating on your movement and expecting the result on the screen is what I think you are getting at, and I am not educated enough in that area of psychology because I studied cognition and how our cognitive processes reacted to environmental stimuli, which involves visual motion to an extent, but not to the extent that would make me an expert in it. The limit to which I studied visual stimuli and cognition got to brain lesion studies and with a B.A. there is only so much you can understand with brain lesion studies. This is why I am going for my Master's degree in behavioral neuroscience.
