Hello,
I got my hands on a new card (Nvidia GTX 770) and I just found out that TSSAA won't work from inside DCS World settings (tested and almost 100% sure), because by default "Antialiasing Transparency" is set to Off in the Nvidia contol panel. Only by forcing it there it's possible to use this feature. In other words if you got a Nvidia card and you think you are using TSSAA, you have to think again.:doh:
Other then that I am wondering what Nvidia control panel settings are best for this sim.
