NVIDIA Surround with GeForce GTX 470 Results Update
Here is the part of the article NVIDIA didn't want to see - our results
of apples-to-apples testing going from 2D mode to 3D mode. In this
section we took the same image quality settings we used in the 2D mode
and simply enabled 3D stereoscopic gaming and re-ran our same testing
scenarios. The reasoning for this was our own curiosity: how much of a
performance hit does enabling 3D gaming at this resolution actually
The reason NVIDIA doesn't like this comparison made is because it
is going to make 3D Vision look bad as a technology when that is
definitely not our intent. I think any consumer should realize that
there is a performance change when enabling 3D gaming modes as the GPUs
are forced to render twice as many pixels. The solution is OF COURSE
to lower the resolution or image quality settings until you find the
new "best" playable features in the 3D mode. And on the next page, we
do just that and write about my experience using 3D Vision Surround as
it was meant to be used.
As for the results below, think of it as an endeavor into the world of scientific theory.
4 Dead 2 was a different story all together. Apparently there are some
complications in the way the AA is rendered in the Source engine that
affects 3D Vision performance pretty drastically as we see a drop in
performance from over 140 FPS to under 20 FPS! I talked with NVIDIA
about the issue and while they agree there may be a bug here they just
say that this is sometimes the result of 3D Vision's "hacks" to get 3D
working across so many different gaming titles. Using NVIDIA's
recommend settings of 4800x900 with 0xAA the game did run just fine in
3D mode at more than 50 FPS.
I should also make sure everyone realizes that with
3D Vision enabled these displays have to run with Vsync enabled
otherwise the 3D effect can be negatively impacted. That is most of
our tests above show the 3D version of the benchmarks settling on frame
rates that are a multiple that corresponds to the 120 Hz refresh rate
Obviously raw benchmark results are not all there is to 3D gaming with 3D Vision Surround - there is also a lot of "experience" data that needs to be discussed. Rather than go over the information we provided again here, I will instead link you to our 3D Vision Surround Experiences page from yesterday's article.
