GPUs Keep Getting Faster, But Your Eyes Can't Tell

itwbennett writes "This brings to mind an earlier Slashdot discussion about whether we've hit the limit on screen resolution improvements on handheld devices. But this time, the question revolves around ever-faster graphics processing units (GPUs) and the resolution limits of desktop monitors. ITworld's Andy Patrizio frames the problem like this: 'Desktop monitors (I'm not talking laptops except for the high-end laptops) tend to vary in size from 20 to 24 inches for mainstream/standard monitors, and 27 to 30 inches for the high end. One thing they all have in common is the resolution. They have pretty much standardized on 1920x1080. That's because 1920x1080 is the resolution for HDTV, and it fits 20 to 24-inch monitors well. Here's the thing: at that resolution, these new GPUs are so powerful you get no major, appreciable gain over the older generation.' Or as Chris Angelini, editorial director for Tom's Hardware Guide, put it, 'The current high-end of GPUs gives you as much as you'd need for an enjoyable experience. Beyond that and it's not like you will get nothing, it's just that you will notice less benefit.'"

    In cutting edge games, FPS still suffers even at low resolutions.

    Many users are going to multi-monitor setups to increase their visualization and even cutting edge graphics cards cannot handle gaming at 1920x1080 x 3 display setups on taxing games or applications (e.g. Crysis).

    Aren't there are other areas of science that a faster GPU benefits namely structural biology and the modeling proteins?

    Even ignoring that, the guy is a fucking idiot.
    He seems to be confused about the function of a GPU- they are doing far more than simply pushing pixels onto the screen. Wake up buddy, this isn't a VGA card from the 90's. A modern GPU is doing a holy shitload of processing and post-processing on the rendered scene before it ever gets around to showing the results to the user. Seriously man, there's a reason why our games don't look as awesomely smooth and detailed and complex as a big budget animated film- it's because in order to get that level of detail, yes on that SAME resolution display, you need a farm of servers crunching the scene data for hours, days, etc. Until I can get that level of quality out of my desktop GPU, there will always be room for VERY noticeable performance improvement.

    And it depends on what part of the eye you're talking about. The Rods (The detail-oriented parts of the eye) see at around 30Hz. The Cones (The black-and-white but higher light sensitivity and faster responding parts) see at around 70Hz. This is why CRT monitors were recommended to be set at 72Hz or higher to avoid eyestrain - at 60Hz the Rods couldn't see the flickering of the display, but the Cones could, and the disparity caused headaches (You could also see the effect if you looked at a 60Hz monitor through your peripheral vision - it appears to shimmer).
