Benchmarks of GeForce GTX 470 (Fermi) in Stereo 3D with 3D Vision

April 18th, 2010 · 14 Comments · GeForce 3D Vision


I was able to get my hands on one of the new GeForce GTX 470 Fermi-based video cards for a bit and of course one of the first things to do was to run some tests with it and 3D Vision to see how well it performs with games in stereo 3D mode. I’ve run the tests with the help of FRAPS taking into account the framerate you really get while playing certain game throughout different levels and while you are playing in stereo 3D mode. All the tests were done at a resolution of 1680×1050 and maximum level of details set with 16x AF and 4xAA and the results were pretty good, the 4xAA turned out to be problematic on just a few of the too heavy titles, but without Anti-aliasing they are also playable in stereo 3D mode.

Test configuration:
– Intel Core i5 750 CPU @ 2,66 GHz
– Gigabyte GA-H55-UD3H Motherboard
– 4GB (2x 2GB) DDR3 1600MHz Kingston
– 640GB Western Digital Black HDD
– OCZ GameXStream 700W Power Supply
– Windows 7 Professional 64-bit
– GPU and 3D Vision drivers 197.41

You can of course have even faster components in your PC than the ones above I tested with and further to squeeze every bit of performance you can overclock your hardware. The above PC configuration can also perform very well with a GTX 480 video card (if you manage to get one), giving you even better framerates while gaming in stereo 3D. But now lets get to the 10 games I’ve tested with and the results they’ve shown in terms of framerate when played with maximum level of details at high resolution and even with AA enabled on the GTX 470.

Battlefield: Bad Company 2
– Average 34.1 FPS, Minimum 27 FPS and Maximum 44 FPS

Call of Duty: Modern Warfare 2
– Average 54.9 FPS, Minimum 43 FPS and Maximum 62 FPS

Crysys Warhead
– Average 19.5 FPS, Minimum 8 FPS and Maximum 28 FPS

Collin McRae: Dirt 2
– Average 39.1 FPS, Minimum 31 FPS and Maximum 48 FPS

Dragon Age Origins
– Average 49.1 FPS, Minimum 30 FPS and Maximum 62 FPS

Fallout 3
– Average 43.9 FPS, Minimum 33 FPS and Maximum 56 FPS

Just Cause 2
– Average 24.9 FPS, Minimum 22 FPS and Maximum 28 FPS

Metro 2033
– Average 16.3 FPS, Minimum 11 FPS and Maximum 25 FPS

Resident Evil 5
– Average 45.5 FPS, Minimum 38 FPS and Maximum 59 FPS

Stalker: Call of Pripyat
– Average 24.4 FPS, Minimum 16 FPS and Maximum 29 FPS

The above results were achieved by playing few different levels of each game and averaging the framerate from them that was recorded with FRAPS, so that you can get a real idea on what can you expect when playing the certain game. Out of the ten games just the following three: Crysys Warhead, Metro 2033 and Stalker: Call of Pripyat were a bit on the edge with maximum level of detail and 4xAA, but by playing them without AA you can actually get enough FPS out of them too in stereo 3D mode (don’t forget that the above results were achieved in S3D mode). And we can of course hope for even better performance results after a few more driver releases from Nvidia for both the new Fermi-based GPUs and for the 3D Vision as these results were achieved with the first official drivers for both. And I’m sure that by improving the drivers some more performance can be squeezed out of the new GPUs both in “normal” 3D mode and in stereo 3D mode while playing games, especially with new and quite heavy game titles like Metro 2033.

Fraps Version 3.2.0 Has Been Released with Updated S3D Support

March 29th, 2010 · No Comments · General 3D News


As you probably know in the last few versions the program FRAPS has support for recording stereoscopic 3D videos for the owners of systems equipped with 3D Vision. But with the stereo 3D mode enabled when you hit the record key you can only record videos in stereoscopic 3D mode, if you want to record a 2D movie you need to disable the 3D Vision and then record again. This is not very convenient as because of that you might miss some important moment that you needed to record in the game while playing in S3D mode, but you actually don’t need the video to be in 3D mode. So in version 3.2.0 of FRAPS you can record 2D videos even while playing the game in stereo 3D mode, just for your convenience. Apart from that in the new version there is also an added loop recording function with 30 second buffer and some major optimizations were done for recording videos from DirectX 10 and DirectX 11 games.

To download and try the latest version of the FRAPS software version 3.2.0…

TriDef 3D Media Player for Video Playback and 2D to 3D Conversion

December 16th, 2009 · 10 Comments · Other S3D Tech

tridef-3d-media-player


TriDef 3D Media Player is the multimedia photo and video player that you get with Acer Aspre 3D laptops and some other 3D displays, but you can as well buy the TriDef 3D experience software separately. Besides the movie and photo player you also get the TriDef 3D Ignition software that is intended to be used to play games in Stereoscopic 3D mode, but I’ll talk about the gaming part with TriDef software in another post and now lets get back to the Media Player…

The TriDef 3D Media Player is intended to be used to play back stereoscopic 3D movies and pictures, along with normal 2D images and 2D movies that can be converted in real time to 3D. The player practically supports all popular movie and photo containers and formats, including support for the proprietary formats used by the developers of the player DDD – .TriDefMovie, .TriDefPhoto and .TriDefPOPvert. The good thing is that you just need to have the proper DirectShow splitter filter and codec in order to be able to play the video in the player and possibly convert it from 2D to 3D in real time. However prior to the just released today TriDef 3D Media Player version 6.5.5 I had some issues with playing back some video files in MOV, TS and MP4 file containers although the system had the needed support installed, but the good news is that the new version has this fixed. I was a bit disappointed by the fact that the player does not support side by side stereoscopic 3D video and I also had some trouble with above/below, although these should be working and with field sequential video too.

What is quite interesting in this player is the feature to convert in real time 2D videos into stereoscopic 3D, even DVD Video and HD clips. However you should know that the resulting 3D effect depends on a lot of factors and sometimes it can be better and sometimes it can be worse, but there are some things that you should be aware in order to get better results. Using higher resolution and better quality videos does help a lot to provide better conversion results, also using videos with steadier and not too fast paced action usually results in better depth perception. A usual problem for 2D to 3D conversions are the fast paced trailers that do have a lot of action and switch between too much different scenes very quickly, so you might want to avoid these, but it won’t hurt to try them just in case. 3D CG animation movies are usually Ok when converted in stereoscopic 3D, but working with 2D drawn or cell shaded Anime the effect of depth is not that good, but there are still exceptions.

And since there are not a lot of stereoscopic 3D movies and even trailers available having an Ok feature that allows you to convert 2D to 3D videos, however being far from true stereoscopic 3D shot or rendered content is still nice to have. You can also do something else with the help of additional software like Fraps for instance (the video recording framerate should be set to match the source framerate and don’t forget to record audio!) – I mean that you can capture the real time video conversion into an Interlaced video format and then share it with other people that do not have TriDef compatible hardware/software to do this themselves, but still have some sort of Stereoscopic 3D setup. After grabbing the converted video stream with Fraps you should reconvert it to something smaller in size, but have in mind that you should maintain high quality of the video compression in order not to get something with bad quality 3D. An example of what you can achieve with the automatic 2D to 3D conversion with the media player is available here Avatar HD Movie Trailer in Stereoscopic 3D Format. Some videos can convert better, other can convert worse… the results depend on a lot of factors, but I’ll say again that this is still not as good as a true stereoscopic 3D content, so don’t get your hopes too high.

The player does not offer a lot of options and the conversion to 3D is almost completely automatic, however you still have control on two things that can roughly be considered to be equivalent of depth and convergence level (the two controls in the right). This allows you to tweak a bit the results in order to minimize the ghosting in the final video or to improve a bit the stereoscopic 3D effect, but still the rest is done by predefined algorithms. And no matter how good are these algorithms for conversion they are still not perfect and can do mistakes like adding depth where they are not supposed to for instance, although considering they do not require any serious setting up they still manage to do their job quite well and don’t forget that everything is being done in real time.
