If you receive an error message saying that “Visual effects could not be enabled”, it is likely that your graphics driver does not currently support visual effects.

In this case, you will not be able to use visual effects with your default graphics driver. However, you may be able to use a restricted driver instead.

If your computer runs slowly, disabling visual effects may improve performance. Visual effects require more system resources, and so older or less powerful computers may not be able to cope with the extra load.
