There are a few system configuration issues, which can dramatically affect EVS performance. We recommend that you read this section and implement these suggestions.
Virtual Memory
The amount of virtual memory that is available strongly affects system performance under Windows. The default settings for virtual memory are inadequate for EVS and MVS. We recommend considerably more virtual memory, and the amount is dependent on the complexity of the models you intend to create. We recommend no less than 1000 Mb and preferably more if you have unused hard drive space. There are also performance and stability improvements if you specify the Initial Size to be equal to the Maximum Size. There is no performance disadvantage to assigning more virtual memory. Virtual memory can be specified in the Control Panel by choosing System, then "Settings" under the Advanced tab, then "Change" in the Advanced tab of the Performance Options window which appears.
Turn Off Full Drag
One of the unfortunate default settings in Windows Vistas and XP is the "Show window contents while dragging" option under the interface for Control Panel>Display>Appearance>Effects. The menu is shown above with the option for ’r;Show window contents while dragging’ turned off. We strongly recommend turning this option off because it causes windows to be redrawn while they are moved or resized. With it off, a ghostly outline of the window is displayed during movement or resizing. This mode dramatically speeds up performance of the EVS Viewer.
Graphics Screen Resolution
The resolution of your graphics screen has the greatest influence on how EVS looks and also on how easy it is to use. EVS has hundreds of individual windows that are used to set the parameters and options for the modules. Although we have tailored EVS to operate at all resolutions from 800 by 600 to 1280 by 1024, we strongly recommend that you operate at the highest resolution that your graphics card and monitor can support. In addition to pixel resolution, color resolution also affects appearance and performance. It is best to operate at true color (24 bit per pixel) or 64k color (16 bit per pixel) color resolution. Most graphics cards can operate at 1280x1024 with 24-bit color. This is the recommended configuration. EVS will automatically adjust the EVS system window according to your screen resolution, but it will not adjust the position (or any other properties) of the console window.
