Guys what game can you suggest which best shows and make use the 3D effect efficiently? Example less lags or slowing down with 3D slider in maximum. Planning to show it to a friend to encourage him to buy and also play a 3DS.
Now that I played with my New 3DS XL for few days all I can say is that regular 3DS stereo-3D is rubbish. Now I can actually play games when using stereo-3D just like I do with my PC and Plasma from time to time.
I would also like to note that having slider on low or full doesn't make any other change than adjust depth of image to users comfort level - some won't see anything unless slider is on top and some get eye strain from same level.
I know what not to get: Virtue's Last Reward.
Outside save corrupting bugs, stereoscopic 3D is simply unuseable. Only thing working is actual character models, outside of that many enviroments, images and cutscenes are simply moved as whole to left and right, meaning part of image is hidden while black bar is put on the other side, which again means 2D image is simply moved little bit to the back but also gives huge eye strain when there's data missing.
Tried Vita version afterwards and that's definitely the version to get for that game.
Usually games using 3D graphics and are done exlusively for 3DS have pretty good stereoscopic mode. However best one I have experienced is actually with Mighty Switch Force, because everything is on clear layer so it looks good and slightly helps to focus on layer where everything is happening. 3D Land also has pretty good 3D but 3D broke too often for me on old XL so I played it in 2D.
for game, i think DOA is most 3D friendly game. but to show 3D works, it is better to show him a 3D video. you can find some in youtube
DOA problem is that frame rate is halved with 3D on, which on fighting game is kinda bad tradeoff. Most demanding games usually have these tradeoffs as stereo-3D does require some horsepower, most games usually add antialiasing on 2D mode.
