Optimizing the Game The Saboteur for 3D Vision

December 9th, 2009 · 3 Comments · GeForce 3D Vision


The Saboteur is a third person action-adventure video game set during World War II. In it you’ll be able to explore an open world Nazi-occupied Paris and some of the countryside and parts of Germany. The primary missions you’ll get all revolve around exacting revenge on high-ranking German officers and officials, and getting to the point to be able to exact vengeance because these damn Nazis killed on of your friends and got you angry. The game has an interesting atmosphere and features and you can consider it to be quite fun to play with some nice elements, but unfortunately it does not do very well if you try to play it in stereo 3D mode…


You should start with the Options menu of the game launcher before starting the game itself in stereoscopic 3D, because you have to be certain of a few things in order not to have surprisingly strange results. Make sure that the Refresh Rate is set at 60Hz, otherwise if you set 120Hz you’ll be forced in a low resolution, using the sixty hertz in the option is Ok, the game actually runs in 120Hz so the S3D works. Also disabling shadows can help you minimize a bit of the strange looking effects (defects) while you play the game. As for the resolution and detail level you should set them according to the specifications of your PC. Have in mind though that the game is actually quite heavy when playing in stereoscopic 3D mode and you can get some stuttering because of the framerate dropping too much when you are in a big open space. An example would be having 58 frames per second in normal 3D, but when I activate the S3D mode in a big open space it drops down to about 15 fps on Core i5 750 and GTX 275 with high detail and 1680×1050 resolution. So you might want to consider lowering the resolution or decreasing a bit the detail level in order to have at least 25-30 fps minimum framerate, otherwise it will ruin your fun playing the game.


Still when you run the game you can notice that there are some weird looking lights and the objects around lights might also look strange and have issues, especially if you increase the depth level more. So a custom convergence level is needed in order to get rid of the different light conditions for the left and right frame and so I did create a custom profile to help you with that. The screenshot above is with my custom settings, also notice that the frame rate is just 22 frames with the maximum details – this was just done while testing the game for S3D, not for playing it, so I needed to lower some of the detail levels to get better performance afterwards. I’ve provided the REG file with my custom convergence settings below, as usual you can download it and import the version for your operating system (32-bit/64-bit) and then just run the game and it will be auto loaded. Have in mind that in order to use this profile with best results you need to lower the depth level to the minimum, otherwise you’ll still have weird lit areas… so turning down the depth level wheel all the way down is needed. And as usual please share your experience using the custom convergence profile if you try it out…

3D Vision Discover Anaglyph Glasses Quick Test

September 27th, 2009 · 1 Comment · Anaglyph Glasses


I’ve finally managed to get a hold of a pair of 3D Vision Discover anaglyph glasses to do a quick test and of course to compare them with a normal pair of paper anaglyph glasses to see if there is any difference. According to Nvidia the 3D Vision Discover glasses are with optimized color filters which should generally improve what you see and minimize color ghosting, although even with normal glasses the result is very good.


Normally you can get the 3D Vision Discover glasses bundled with some games as a promotion, for instance World of Warcraft or Batman: Arkham Asylum, bundled with some new video cards and of course from different trade shows where Nvidia is participating. Unfortunately these are still not available everywhere, so you may have some hard time finding the glasses just to try them out… actually it might be even easier to try the 3D Vision shutter glasses easier that the anaglyph ones as was the case in my country, but anyway. If you can’t get a hold of 3D Vision Discover glasses, just try to get a pair of normal paper anaglyph ones… the results are pretty close.


What you can notice even before putting the glasses on is that they are a bit bigger than the normal anaglyph paper ones and this is realized with the idea to be more comfortable and suitable for different size and aspect of displays. The red and cyan color filters are quite bigger on the 3D Vision Discover and if you take a closer look you’ll be able to find a bit of difference in the tint of the cyan filter, which is actually a bit more bluish here. There is also a very slight difference in the red color filter, but it is much harder to distinguish with a naked eye compared to the normal white paper anaglyph glasses. How this affects things when using the 3D Vision Discover glasses compared to the plain normal ones is a different story, but you should know there is some difference…


If you try the two types of anaglyph glasses one after another quickly you’ll barely notice any difference or not notice anything at all. This is because generally both pairs of glasses do provide quite good results, especially considering they are free or very cheap to get and do not require too much from the user like in the case with the better shutter glasses alternative. You need to take a bit more attention adn then you’ll start to notice where the 3D Vision Discover glasses do provide better results as the difference is actually in the small details. Still these small details are the things that can improve significantly the experience you get form the 3D Vision Discover, so it is important to have an idea what to look for if you are really interested. In general what the 3D Vision Discover glasses do is to decrease the color ghosting you see through the red and cyan filters or at least make it less apparent and annoying to the user. The color ghosting here refers to seeing some sort of red or bluish “shadow” or a “double image” of some objects. So with the 3D Vision Discover you see less color ghosting and if there is a place with some ghosting around a certain object the colors is less brighter and the ghosting is harder to notice… and easier to be ignored.


If you have already tried normal anaglyph glasses you should not expect that much of a difference if you obtain a pair of 3D Vision Discover and the issues caused by the anaglyph technology are still there. I mean that with every pair of anaglyph glasses you will kind of lose most of the color reproduction of the screen and the image you see with have some depth and pop-out effect, but it will seem almost as it is black and white. Still you’ll be able to perceive some colors, but not all of them and although you’ll be able to take advantage of the Stereoscopic 3D technology it is just something to try and then to get your interested in better solutions that of course have their price. You should also be aware of the fact that the anaglyph glasses do tire the eyes more and are not suitable to be work for hours non-stop without taking some break from time to time. And there is some after effect after you take them off, for a few minutes after that one of your eyes will be seeing in a bit colder tones and the other one in a bit warmer tones. So just try closing one of your eyes and then switching to the other to see this effect of the eye actually adapting to the color filter it has in front for some time. Of course after a few minutes without wearing the glasses everything is back to normal and you should not worry about some possible negative effects of that. Just don’t wear the glasses for too long, especially if it is your first time, because this is tiring for the eyes and the brain. After all this is a kind of new sensation that your body has not experienced so far so you need some time to get used to it and then you should be able to get even better results.

Don’t forget that anaglyph technology and the free 3D Vision Discover mode in Nvidia’s driver do not requite special hardware like a 120Hz monitor so you can pretty much try them on your current gaming PC or even laptop. The only requirement would be to have an up to date video card that is Nvidia based and for good enough performance it is best to have a VGA that can provide higher framerates. So still it is good to have a middle or high-end class video card for playing comfortably in more heavy on hardware requirements games…

Here is how you can use the free 3D Vision Discover mode on Nvidia-based VGA…
