Is there a 3D Vision/surround review on the GTX 480 / 470?

[londonbairn]

Nvidia should concentrate on more important things, like reducing the size of their core, costs and maybe their marketing team.

Lol are those 3 graphs credible? Thats a seriously harsh performance hit for something Nvidia are trying to sell to us :O

I wonder do you need the high resolution for it or is that purely the users choice (ie no silly res lock on it)

Most definitely, Tom's Hardware has some 3D Vision benches and a few other sites, and they show a constant halving of FPS when you turn 3D Vision on.

3D gaming is really awesome, if you have the money and the time to game then its highly recommended. I just go round to a friends house when I have time.

I'm not sure on the exact implementation Nvidia have but a naive solution would render at half the speed. However, with clever drivers the reduction could be decreased significantly.

I'm not sure how you've figured that one out considering the GPU has to essentially render the same screen from 2 different angles, thus doubling the load.

No, most of the view port is the same. Geometry and textures, shaders can be shared.

^ This.

As all the assets for the scene have already been sent to the graphics card to render one image, it shouldn't take a s long to render the second image. I would have thought that a halving of frame rate would be the worst case scenario, not the best case.

However, in my experience with 3D Vision Discover, the effect is completely awesome (yes, even in nasty Red/Cyan).

One of the best games I've tried in 3D is Battlefield Bad Company 2. And it does seem to run at better than half normal frame rate, but that could be a placebo effect

Guess it shows that NV can't even get their 3D stuff to work without issues

I wouldn't say they have an issue, it performs as to be expected in the way it is implimented.

I'm waiting for ati's answer and for the 120hz monitor market to get abit more competative.

Once you have one "half" rendered, rendering the 2nd half SHOULD NOT need to be done completely - which means it should not drop the performance by 50%.

Thanks for the input guys and it never dawned on me it wasn't actually in the current driver release yet..

Suppose ill know before the reviewers do in that case roll on.... erm whenever.

 

[no_1_dave]

I will be buy a 470 or 480 cos my 275 is struggling slightly in modern games running 3D. Only slightly though!

I would be interested to compare some 3D vision results with your system and mine in its current state, I'm currently running on a GTX280 E8600, EP-45-UD3P, DDR2 system and would like to see if the cpu has much of a bearing on the performance of stereo.

Obviously if they're very similar then its gpu bound and i wont be looking at yet another upgrade following the introduction of a new card.

PM me if you're interested and we can see if we have a anything in common so far as games library is concerned.
