Posted from the Prepar3d Website....

Prepar3D v3.4 Hotfix 3 – SLI Update02-01-17The Prepar3D team is excited to announce the third Hotfix update to Prepar3 v3.4 (  It can be downloaded immediately from the Purchased Downloads section of the website.
This hotfix is to address reported issues and incompatibilities with SLI mode of NVIDIA hardware.  We would like to extend a strong thank you to the NVIDIA team for working with us directly to resolve these issues!  If using NVIDIA hardware, please ensure your graphic card drivers are updated to at least 378.49 before updating to Prepar3D v3.4.22.19868.
For those that are interested in updating, only the Client installer is required for Prepar3D v3.4 Hotfix 3.  The Content, Scenery, and SDK installers are optional. You must first have Prepar3D v3 installed to utilize the Client only installer.
To install the new Client, first uninstall your current Prepar3D v3 Client in Programs & Features / Windows Control Panel.
The Prepar3D v3.4 Client hotfix will require you to reactivate your product, however if you have an internet connection or have not made any major hardware changes between installations this should not be an issue. For more information please view the Prepar3D v3 Download and Installation Directions.

Not installing it.  :idiot:

None of these fixes are essential for my sim.
Moreover, there are reports that recommended NVidia driver has serious memory leaks. People suggest to rollback to a previous driver which seems to work with Hotfix 3 just fine.
