Anyone hear if there will be a patch so that COx will use NVISION??
I know that other video games support it and holy crap would that be cool

Real 3D is the sauce.

Wrong forum, kiddo.

Layered Vision is handled by the driver separating the camera positions of the game into separate rendering views, not by the game. I just went over this not long ago: http://boards.cityofheroes.com/showp...27&postcount=4

okay. You seriously need to read some my posts on the subject of Multi-Monitor / 3D Vision Surround Support:

As you can see, the subject comes up on a regular basis. You are not the first poster to think that Stereoscopic 3D is something that has to be enabled by the developer.

Stereoscopic 3D is handled by the graphics driver, not by the game. In a nut-shell, Stereoscopic 3D is simply taking the camera position given by the game, then separating that camera position into two different frames of reference, then feeding back the off-center angles to the monitors.

As mentioned many of the times this subject has come up before, various 3rd parties have been doing this angle separation outside of original developers support for years, such as IZ3D and Nvidia. In most (95%+) of the games Nvidia offers Stereoscopic support for there has been absolutely zero input or work done on the game to support Stereoscopic viewing on the part of the game developer. All of the work to support the stereoscopic rendering is done in the Nvidia driver.

So if you want Stereoscopic 3D support, you need to go talk to Nvidia. Not Paragon Studios.

Let me repeat that.

Now, since I am sure some jerk is going to bring up multi-monitor support, aka Matrox Triple Vision, AMD Eyefinity, and the deliberately confusingly named Nvidia 3D Surround Vision, these types of technologies are not entirely handled by the graphics driver.

In the case of City Of Heroes, the game essentially includes it's own internal window manger, allowing the positioning and in many cases, resizing of the internal dialog windows. The window manager seems to be one of the technical reasons City of Heroes breaks when trying to run in triple-monitor configurations. It's not the only one, but it is one example where the game developers do need to do some internal work to account for how the game will perform on a 3rd party feature.

Multi-GPU support is another such situations. CoH famously doesn't support Multi-GPU modes, mostly because neither AMD nor Nvidia have fully matured OpenGL 3.x / 4.x drivers and CoH Ultra Mode was the first commercial OpenGL 3.x fast-pass oriented rendering system they had to work with. In many cases Multi-GPU support can be forced at a driver level, but there are some code-optimizations the developers can perform on graphics engine to leverage the presence of multiple GPU's.
