Driver Specific Instructions
Nvidia GeForce 3D VIsion
If you are using an Nvidia GeForce 3D Vision solution, or any hardware that is being driven by Nvidia GeForce 3D Vision drivers (e.g. 3DTV Play, Zalman+Nvidia combo, etc.), please activate the “advanced” feature of the drivers. Unless the advanced mode is turned on, you won’t be able to adjust the convergence or “pop-out” abilities of your games.
The default keys to control convergence are CTRL-F5 and CTRL-F6. In some instances, Nvidia has locked out the convergence controls with certain titles, and you can indicate this limitation in GameGrade3D where applicable.
TriDef Ignition Drivers
TriDef Ignition regularly turns its auto-convergence feature ON by default. When active, the game will dynamically adjust the convergence and 3D appearance depending on what you are looking at, and the screen will alter and change from one setting to the next automatically. While some titles benefit from this feature, it’s usually unnecessary and can hamper game performance.
While testing, auto-convergence has to be turned OFF in the game because camera angle problems need to be accurately scored so they can be fixed, and this feature makes consistent separation and convergence settings impossible. In cases where auto-convergence makes a positive improvement to the game’s stereoscopic 3D performance, please feel free to include your remarks in the comments section of your submission – though this won’t impact the game’s actual score in GameGrade3D.
Virtual 3D must also be turned off. Virtual 3D is DDD’s 2D+Depth implementation. Many gamers like 2D+Depth because it keeps the FPS performance very high, but comes at the cost of being a pseudo 3D experience compared to a true dual camera rendering. Since the expectations and problems associated with 2D+Depth are very different from what you get with traditional 3D rendering, GameGrade3D doesn’t have the ability to rate 2D+Depth games…yet.
Where possible, users are encouraged to try the advanced 3D settings. TriDef Ignition offers the ability to control the gun, scene, and sky as unique 3D elements, and this makes it easier to have a well balanced scene in 3D. Always use “fixed” settings (not auto-convergence or automatic settings). This is targetted more towards advanced users, but with a little practice, the results can be very rewarding.
Always remember to export your favourite DDD game profile so you can attach it to your GameGrade3D submission so others can duplicate your results!
iZ3D Stereoscopic 3D Drivers
Similar to DDD drivers, auto-convergence must be turned off 100% of the time.
When testing for a combined depth and pop-out experience, there may be instances where the gun separates too far apart and is uncomfortable to view in 3D. iZ3D has a feature in their driver labelled “Simple Projection Method”. If this solves the problem, please document in your game submission so others will know.
iZ3D doesn’t have a profile export function, but it does have configuration files. If you have special settings that make a big difference, we recommend attaching them as a .TXT file to your game submissions.
Native Stereoscopic 3D Support
“Native” stereoscopic 3D means that the actual 3D display options are programmed into the game itself, and a third party driver is not required. Native 3D outputs found in a game menu could include anaglyph, side by side mode, AMD’s QuadBuffer HD3D output (when not associated with DDD or iZ3D drivers), dual output, and more.
Games that have “driver profiles” or have a driver certification (e.g. “Nvidia GeForce 3D Vision Certified”) don’t qualify as native, and are handled differently in GameGrade3D. Always treat Nvidia GeForce 3D Vision support as driver based because the Nvidia category of certification will accurately record 3D quality regardless of the underlying implementation.
Games that are known to use 2D+Depth technologies should be excluded from GameGrade3D. Samples of this include Crytek’s Crysis 2 in 3D, Trioviz, DDD’s Virtual 3D mode, and more. While MTBS has nothing against these technologies, the rules and visual expectations are very different – and it really is apples to oranges. We are looking at 2D+Depth technologies in a future revision of GameGrade3D.
