60 FPS Cap?

So why is there a 60 fps cap?
I for one would love to have this removed.

that counts as 120 cause 60 per eye. That's plenty, but displays prevent glasses to shutter twice per frame (240hz), we need faster displays with better color primaries.

how does that count as 120, when it's processing two images. It's still technically 60 fps.

I have to go, and let others 'interfere' , I'm very happy theres a topic about something else than the usual resolution freakshow!! This sounds like *straight* CRT talk , chheers /thumbup.gif' class='bbc_emoticon' alt=':thumbup:' />

Technically, I don't quite understand as well. Just wondering, if I can remove the cap, some games will definitely runs smoother.

Technically, some humans can detect up to around 500fps, or so i've read (somewhere, i don't remember). Its said [url="http://www.100fps.com/how_many_frames_can_humans_see.htm"]here[/url] that pilots can detect and [b]identify[/b] the type of plane shown in 1 of 200 fps. I find 60 frames per second to feel solid, yet, i would love to see what 240+ looks like.

This is good, I'm glad people feel the same way I do. We spend a lot of money on these computers to get high FPS. Then they put FPS caps.

I assume you are referring to 60fps cap in 3D. The reason for that is the technology. Because the monitors work at 120hz that allows 60 hz per eye. For 3D to work you have to use Matched left and right frames so no matter what your screen refresh rate is you can only use half that rate per eye. You don't want a Left frame 1 image and a right frame 2 image. That would break the 3D effect. Based on that games and software are locked at 60FPS per eye, which is technically 20 frames per second total just that it's left and right eye pairs.

Until a tv can take in a 240hz source and output at 240hz we wouldn't be able to see 120hz per eye in 3D.

even playing games out of 3D on let's say a 60hz screen, what is the point of having a video card outputting 120fps. that means every other frame is lost and not displayed on the monitor since in that 1 seconds only 60 of the 120 created frames can be sent to the device and displayed.

1. The technology [b]barely[/b] works with the eyes flipping this fast! I don't see 120FPS happening any time soon.

2. For reaction purposes, you DO have 120fps. You've got 60fps in each eye but they alternate. So, if something suddenly appears in front of you, you'll see it in 1/120th of a second or less.

3. The pilots doing 200fps is pretty irrelevant but I'm not going to fight you much on it because you folks are paying to push graphics tech further. I'll just say I think you're being silly and, if you don't believe me, all the better for me! /wink.gif' class='bbc_emoticon' alt=';)' />

There's a FPS cap to go with VSYNC, so you don't get tearing in 3D...

I was wondering when someone would post this. /thanks.gif' class='bbc_emoticon' alt=':thanks:' />

This is because the LCD monitors max out at 120Hz. So the game is locked at 60FPS (which converts to 120Hz since there are 2 frames per eye). The Nvidia glasses could probably go higher. I know I have used older shutter glasses at 170Hz, and it looked great (on CRT, at least). I wouldn't be surprised if even some HDTVs could be made to do this, as they have display panels that do interpolated 240Hz. However then you get into a bandwidth limitation. DL-DVI could not support 1080P@240Hz and certainly not on HDMI. Even DisplayPort might not be able to handle that (at least not current versions). So its just not technically feasible at the moment.

There isno frame.cap on my older hdmi 1.3 hdtv. With sync off. I used to get over a hundred fps in batman aa. I think :3d games look better with vcync off, at least in 3d with high frame rates. Metro 2033, which is still the best and most advanced 3d game came with vcync turned off from developer.

Yes in 2d, a lot of people don't mind a little screen tearing to get 100's of fps. However, I've seen screen tearing in 3d when an app messes up and its NOT pleasant! For that second a screen tear happens, left/right is reversed and can really give some heavy nausea. /pinch.gif' class='bbc_emoticon' alt=':pinch:' /> Just horrible.

60fps is butter smooth. Why do you really need more? LOL I have SLI 570's not for getting 200 fps in portal2 or black ops... but a SOLID vsync'd 60fps no matter how much crap is being rendered on screen - in 3d. /thumbup.gif' class='bbc_emoticon' alt=':thumbup:' />
