| General Limitations Common To All Cards |
| Limitation |
Hardware Anti-Aliasing does not work on Windows Vista
platforms. |
|
| Solution/Workaround |
Use the software Anti-Aliasing found under the
WindowDisplay->Anti-Alias->Shaded Anti-Alias menu or
upgrade to Windows 7 |
|
| Limitation |
Shading maps with file textures may look incorrect in
Hardware Shade |
|
| Solution/Workaround |
Use procedural textures or do not use pure white values in
the file texture |
|
| Limitation |
Pull down cascading menus in rare cases may fail to accept
mouse input |
|
| Solution/Workaround |
Do not release mouse button when selecting cascading menu
items or restart Alias |
|
| Limitation |
Missing refresh when
using mouse scroll wheel to dolly camera in Hardware Shade mode |
|
| Solution/Workaround |
This only occurs when
shaded Anti-Aliasing is enabled |
|
| Limitation |
Pick boxes in Action
Window leave trails |
|
| Solution/Workaround |
This is only a display
artifact which is cleared when a window refresh occurs |
|
| Limitation |
Slow selection
performance with Anti-Aliased surface display. This is more
noticeable with large datasets |
|
| Solution/Workaround |
Disable driver
controlled Anti-Aliasing in driver control panel or Application
control Anti-Aliasing through Preferences->General
Preferences->Draw |
|
| Common Limitations |
| Limitation |
Erratic turntable performance when viewed with timeslider
on dual monitor configurations |
|
| Solution/Workaround |
Disable timeslider or run on single display |
|
| Limitation |
Intermittent selection performance degradation if
AntiAliasing is enabled with 'Export Image' |
|
| Solution/Workaround |
Restart application if you encounter this problem. |
|
| Limitation |
Pick boxes in Action
Window leave trails |
|
| Solution/Workaround |
This is only a display
artifact which is cleared when a window refresh occurs |
|
| Limitation |
Slow selection
performance with Anti-Aliased surface display. This is more
noticeable with large datasets |
|
| Solution/Workaround |
Disable driver
controlled Anti-Aliasing in driver control panel or Application
control Anti-Aliasing through Preferences->General
Preferences->Draw |
|
| NVIDIA Limitations |
| Limitation |
Slower framerates when
running DualView display configurations |
|
| Solution/Workaround |
Consider using a
Horiztontal Span configuration instead of DualView if you notice
significant performance loss when running Alias |
|
| Limitation |
Certain Nvidia hardware
will exhibit inaccurate Anti-Aliased model display under certain
conditions. This will typically occur with Curve on Surface objects
with a high rate of curvature. The wire display will appear
noticeably thicker than the rest of the model. This is a display
issue only. |

| Solution/Workaround |
None |
| ATI Limitations |
| Limitation |
Poor performance with
single sided shading in Hardware Shade |
|
| Limitation |
ViewCube can contribute
to a perceivable performance degredation with draw speed |
|
| Solution/Workaround |
Disable ViewCube in
General Preferences |
|
| Limitation |
Significant drop in
interactive performance both with playback framerate and selection
if there are open windows obscuring any of the Alias viewports |
|
| Solution/Workaround |
Use Windows Classic
Theme under Display Properties |
|
| Limitation |
Display artifacts may
occur during modifications to shader attributes or Hardware Shade
settings while Hardware Shade is active. These artifacts should only
be momentary and are cleared with a refresh |
|
| Limitation |
Slow selection
performance with anti-aliased surface display |
|
| Solution/Workaround |
Disable Anti-aliased
surface shading in Preferences->General Preferences->Draw and
