## Running the Tool in DirectX Mode

TWL ManualEditor must run in DirectX mode to run fast enough to make manual-related work practical.

(Running in DirectX mode makes use of DirectX, which allows the program to render the data quickly.)

The performance of your computer's graphics chip has a significant effect on DirectX operations.

Due to the variety of hardware that is available for graphics chips, we have not been able to verify operation in all environments.

### Graphics Chips for Which Operation Has Been Confirmed

So far, we have confirmed that the following graphics chips allow for practical operation of the software.

#### - NVIDIA Quadro FX series (or equivalent)

This graphics card supports hardware vertex and lighting operations.

This graphics chip is mostly used in graphics cards that are separate from the motherboard.

#### - Intel GMA 3100 series (or equivalent)

This chip is mostly used in the integrated graphics that are built into the motherboards of business computers.

### Figuring Out Which Graphics Chip You Have

#### - Using the System Information dialog

Click Start → All Programs → Accessories → System Tools → System Information to display the System Information dialog box.

From the tree view in the System Information dialog box, select System Summary → Components → Display, and note the value that appears for Adapter Type.

#### - Using the DirectX Diagnostic Tool

Note: This method requires that DirectX be installed.

From the Start Menu, choose Run, type `dxdiag`, and press ENTER to launch the DirectX Diagnostic Tool. Select the Display 1 tab and note the value that appears for Chip Type.

## Problems with IntelliPoint Compatibility

A bug has been confirmed in environments where IntelliPoint (a Microsoft-manufactured mouse driver) is installed. When using this development tool in DirectX mode, re-rendering a page window illegally overwrites menus and windows.

Sample Case

The following methods have been confirmed to be effective in working around this problem.

1. Downgrade IntelliPoint to a version earlier than 5.5
2. Run IntelliPoint in Windows 2000 Compatibility Mode

For (1), old versions of IntelliPoint can be downloaded from Microsoft's website.

(Install a version that does not implement the Instant Viewer feature.)

For (2), right-click `iPoint.exe` and configure its mode from the Properties → Compatibility tab.
