One way way to improve performance in wysiwyg’s Shaded View is to tweak its settings, along with your video card’s settings. It is important to remember that as with all things in computers, higher quality comes at the price of lower performance, so in order to increase performance, some quality must always be sacrificed—how much depends on the particular file being worked on, since no two files are the same. The following suggestions will all help increase performance.
Tweak the Shaded View Settings
Shaded View settings are adjusted via its View Options window. To get to this window: right-click in a Shaded View and select View Options from the pop-up menu that appears (or simply type V while in a Shaded View) and click the Simulation tab in the window that appears.
1. In the Simulation tab, when working with Volumetric Beams, ensure that the Detail slider is set to 0; for pre-visualization and/or live simulation, this slider should always remain in this position. Increase it only when/while exporting the Shaded View–and only if quality is unacceptable for an exported image when it is set to 0.
2. Seting the Beam dropdown to ‘Low’ will speed things up, but the beams’ quality will (naturally) decrease. If the quality is unacceptable, increase the Beam dropdown to ‘Medium’ (and then back to ‘High’ if needed) and/or raise the Detail slider until you find an acceptable balance between quality and performance.
3. If Volumetric beams are unacceptably slow no matter what, switching the Quality Mode dropdown to Enhanced (and, further if necessary, the Beam dropdown to ‘Medium’, or even ‘Low’) may increase performance. Perform all your pre-visualization/live simulation work this way, and only go back to Volumetric Beams when you wish to export an image to present to your clients.
4. Performance will also increase if some or all the following checkboxes are disabled (i.e. unchecked): Soft Shadows, Footprint Focus, Materials, Reflections.
5. In the Performance tab, enable The Auto-Adjust FPS and allow wysiwyg to automatically and dynamically set/adjust the quality of the Shaded View based on the parameters that you define here (i.e. Target FPS and Minmum Quality).
6. Performance will also increase if some or all the other checkboxes in this tab are disabled.
Change the Video Card Settings
The following changes to your video card’s settings are recommended, as they will provide performance increases. Please consider creating a “wysiwyg” profile within your video card’s settings which stores these settings, and applying it every time wysiwyg runs; this process can be automated–please check your video card driver’s documentation for details on how to do this. Settings for nVidia video cards are adjusted via the nVidia control panel, while settings for AMD video cards they are adjusted via the Catalyst Control Center utility found in the Windows Start menu.
- lower or disable Anisotropic Filtering
- lower or disable everything that has to do with Antialiasing
- disable Texture Filtering
- disable Triple Buffering
- disable Vertical Sync (note that doing this will cause “tearing” artifacts to appear, on the screen, but if the low quality resulting from adjusting the Shaded View settings is too low, this may be your only/last option)
After making the adjustments above, wysiwyg must be restarted (this does not mean re-starting the computer) in order for them to take effect. If performance has increased dramatically (which is not unlikely), you may be wish to consider re-adjusting the Shaded View settings in order to increase quality.
If even after all of the above performance is still not acceptable, you may have to resort to optimizing the geometry in your file. Please read through the following thread on our Forum in order to learn about optimizing geometry; please do not omit clicking on the “Part 1” and “Part 2” links in the first message (and reading the information revealed by each): http://forums.cast-soft.com/index.php?threads/geometry-optimization-and-file-efficiency.283/.
Above and beyond all this, using appropriate hardware to run wysiwyg is the key to adequate performance: it is not reasonable to expect a machine which only meets wysiwyg‘s minimum hardware requirements to be able to handle the simulation of hundreds of fixtures lighting a complex set, even if “extras” such as multi-media (i.e. videos) and/or moving scenery are not being used. In order to ensure that the computer you are using is properly-equipped to serve your needs, it should meet wysiwyg’s optimal requirements. The minimum and optimal system requirements lists are updated regularly, and always available at http://www.cast-soft.com/content/wysiwyg-system-requirements; for more information and comprehensive details regarding hardware for a wysiwyg workstation, we recommend reading through the wysiwyg Hardware Guide, http://www.cast-soft.com/wysiwyg/tip/view/selecting-hardware-for-a-wysiwyg-workstation.
Finally, it is important to remember to keep your hardware drivers, especially the video card driver, up-to-date.
