Transparent surfaces require precise ordering and rendering of the model to accurately reflect what is visible behind the object. Both front and back faces need to be considered as well as colours.
Both options should be cleared to result in a lower quality. transparency display, both when the model is stationary and when moving. This will allow the model to be panned and rotated more quickly. Selecting High quality for normal view mode will cause the transparency to be high quality when the model is stationary. Selecting High quality for dynamic view mode will cause the model to be high quality when the model is being panned or rotated.
Automatically load components lightweight this is a choice that depends on the complexity and size of the assemblies you work on. There is a similar option in Large Assembly Mode that will load components lightweight when assemblies reach the large assembly threshold. If you routinely open assemblies below the large assembly threshold but only work on a few of the components, then this option should be selected. Level of detail, moving this slider to the far right will allow the model to be moved, panned and rotated faster. This option causes the smaller components to change to blocks when you move, pan, zoom, or rotate the assembly. Once the assembly stops moving, the components will again be displayed normally.
Always resolve sub-assemblies, this option should be cleared. If it is selected, subassemblies are automatically resolved when the top level assembly is opened, lightweight. This removes some of the advantages of opening the assembly lightweight.
Check out-of-date lightweight components, generally, you should make sure that components are up-to-date when working on an assembly to keep from working on something that has already been changed. Choosing the option Indicate will cause a flag to be shown in the FeatureManager® design tree for all out-of-date components. This allows you to update only components that are needed rather than all components and in doing so, increase performance.
Resolve lightweight components, if you load components lightweight but then need the component resolved to perform some task, setting this option to Always will save a step. Always will resolve the component automatically if the operation you are performing needs the component resolved. This saves time by not having to agree to resolve the component.
Rebuild assembly on load, this is an option that should be set to Always. This will rebuild the assembly when it is opened, avoiding the problem of working on out-of-date geometry. While it will take longer to open the assembly, this additional time is better than working on incorrect geometry, which can cost even more time.
Mate animation speed, if the mate animation speed is set to any position other than Off, SolidWorks must calculate intermediate positions for components between where they start and where they will be once mated. By turning this off the intermediate positions do not have to be calculated and the component will jump directly to the mated position.
Software OpenGL, with no files open, examine Use software OpenGL. If it is checked and greyed out, you need a new video card. When SolidWorks launches, it checks the video card against a list of video cards that meet the requirements for SolidWorks. If your card does not meet the requirements, SolidWorks will automatically select Use Software OpenGL. This means that instead of your video card running hardware OpenGL, the tasks will be done by the software. This further taxes the CPU and slows down your system. Here again, you are balancing the cost of new equipment against the time lost by not having it. As the assembly size grows, using Software OpenGL will result in significant lost time and user frustration.
No Preview During Open if a preview is not shown when a file is opened, more memory can be dedicated to the resources to load the files into memory.
