I'm running into an issue with both Fallen Enchantress and Fallen Enchantress: Legendary Heroes.

The in-game anti-aliasing crashes my machine when I start the game. For Legendary Heroes, it's enough to set the in-game anti-aliasing setting to disabled in the settings menu to get the game to work. For Fallen Enchantress, that's not enough; the game will load to the main menu but the New Game button causes it to crash. The only way I am able to get Fallen Enchantress to start a new game is to pass it the /nomultisample switch on the shortcut line.

I have had other games behave the same way if they include CSAA modes (those will crash the game on start) as support for CSAA was apparently removed by Nvidia on all Maxwell GPUs. Unfortunately, whatever AA these two games use is also apparently incompatible with my 980GTX.

Unfortunately, while I've gotten the games themselves to work, they are ridiculously jaggy. I haven't been able to get any of the driver-forced anti-aliasing modes to do anything, and the one injector I know how to use (InjectSMAA) crashes the game immediately.

Does anyone know of any way to get anti-aliasing in this game that does not rely on the built-in settings that I can't use?

Some suggestions from Stardock support put me in the correct direction. Specifically, the driver version I was using (361.43) was causing issues with driver-forced AA. I have stepped back to 359.06 and have been able to get driver-forced AA to work using the following settings:

Anti-aliasing compatibility: 0x00001245
Anti-aliasing - Mode: Override any application setting (0x00000001)
Anti-aliasing - Setting: 8xQ [8x Multisampling] (0x00000025)
Anti-aliasing - Transparency Multisampling: Disabled (0x00000000)
Anti-aliasing - Transparency Supersampling: 8x Sparse Grid Supersampling (0x00000038)

(Note: These are also the correct settings for Elemental: War of Magic, if you happen to have that game through other sources.)

In addition, I am able to remove the "/nomultisample" command line switch from Fallen Enchantress.

The in-game anti-aliasing options still crash either the computer or the video driver, but I no longer care, since the driver-forced AA is much better anyway now that it works. If anyone needs to see how the settings are configured, I've attached a screenshot of Nvidia Inspector showing the settings for Fallen Enchantress.
