I'm a HUGE believer in 3D (and have been a 3D user in the past, although I'm not using it currently.)
That said: ALL of my current hardware purchases were made with the idea of implementing 3D once again in my own userspace, so I've gone "full Nvidia" for my new (and also current) video card as I believe Nvidia, alone, offers not only the best support, but also a literal "faith" in the idea of good 3D that the good people behind AMD still do not. Or just have not (yet?).)
As I'm currently in the midst of a new PC build, my hope is that this commentary will perhaps be understood as more of a truth and less of a simple "fanboy" attitude: I AM, quite literally, backing up this belief (in 3D) with my own hard earned dollars--parts for this next PC (the final parts should arrive early next week) were certainly purchased with the possibility of using 3D (both older and current versions) well in mind.
All that said, I'm also a 3D believer MOSTLY...perhaps even ONLY...when that 3D content is viewed "lifesize(d)." IMO, 3D FAILS pretty quickly when it isn't viewed lifesize(d). Perhaps this is only by a matter of +/- 10% where FOV is concerned.
Some of you might be thinking: HUH? Wtf is FOV or lifesize(d)...and why should I care?
FOV is "Field of View." Whether we realize it or not, all of us humans (those who have vision in both eyes) have a FOV of something like 180 degrees. This means we can (using both eyes) usually see things in front of us...and about 90 degrees (1/4 full circle) out to each side.
Put another way: those events which happen in FRONT of the middle of our heads can probably be seen by us...and those which happen BEHIND our heads probably cant.
We view the world around us in 3D (because of our two working eyeballs) every day and in every waking hour. And we view that world LIFESIZE(D). We see our car keys...our own fingers and hands...our cell phones....and our PC keyboards and mice...lifesized.
EACH of these objects encompasses a certain, given segment of our view (from our own two eyes looking ahead). So I expect (whether I realize it or not...I EXPECT my own mouse to "look" like it's of a certain size sitting in my hand. Neither too big, nor too small.
PC monitors, however, typically are configured to display within 3D games or even apps...a much smaller FOV than 180 degrees ahead of us...and unless we adjust for this when viewing 3D,
we are thus perhaps likely to be somewhat somewhat "underwhelmed."
I adjust for this in part by using a PROJECTOR...rather than a monitor. And the projected image, in my case, is both BIG, and also quite CLOSE to me too. Just 3 away...but something like 7 or 8 feet wide.
Aka.....HUGE! Unusual? Certainly, yes.
But, this also makes ALL the difference, IMO. It more accurately is able to reflect the way our two (normally sighted eyes) DO see the world around us.
IF the image you see is both BIG and CLOSE TO YOU, you are more likely to understand (when you first see it) just what 3D has to offer you. IMO this is because the objects (particularly the close objects you are most familiar with) will seem to be lifesize.
But if you see typical "3D" only on a smaller screen in front of you, then it's likely you will be underwhelmed. Sad, but also, IMO, quite true.
Even 2D images...viewed lifesize(d) are far superior to conventional monitor-sized viewing, IMO.
I should know. I'm currently driving (my simracing)...online....in front of a lifesize (but only 2D) projected image. A nice projector, and certainly a full size image, yes...but still not 3D.
That said, I'm usually/or even often right up at the front of the field too.
Lifesize viewing certainly doesn't HURT me in any way.
Why would it when it truly "rocks?"
