How to create your own custom NVIDIA SLI application profile using Coolbits:
The following steps allow you to create a new SLI application profile for a title not currently supported:
Step 1. If you already have Coolbits installed, you can skip to Step 2. Otherwise, click on your Start button and select Run. When the command box opens, type "regedit" (without the quotes) and press OK. With the registry open, go to HKEY_LOCAL_MACHINE \SOFTWARE \NVIDIA \Corporation \Global \NVTweak. Once there, right-click inside the right window, and choose "New>DWORD value". Name the value "Coolbits" (without the quotes).
Step 2. Within the Registry Editor, right click on Coolbits and choose Modify. Change the Value data to "8" (without the quotes) and click OK.
Step 3. Open the NVIDIA Display Control Panel and select "Add Profile", located on the Application profiles page (under Performance & Quality Settings):
Step 4. Create your new profile name and then click "Browse" to associate the profile to the application executable (the application that you are creating the profile for), then Click "OK".
Step 5. Next highlight the "SLI rendering mode" setting and choose your desired SLI rendering mode. The available rendering modes are:
  • Auto-Select*
  • Alternate frame rendering
  • Split frame rendering
  • Alternate frame rendering 2**
  • Single-GPU rendering
*Driver automatically selects the multi-GPU rendering mode

**Alternate version of AFR - may provide better performance than AFR on some applications
Step 6. Once completed, Click "Apply" and your new SLI Application Profile is ready for use!
