Those with lower end machines that can't run Combined AA settings at acceptable frame rates should try setting terrain to "low". This will heavily reduce the detail of the textures in the distance, and remove the aliasing that is associated with that detail.

High end machines can significantly remove the aliased distant terrain by forcing "Combined" AA at 4X using nHancer. Set up the other settings as you had them (remember to allow RoF to control vSynch!), but you will probably need to reduce AF settings, driver level Texture Quality, and turn on optimizations to help offset the performance hit of running combined AA. (In my experience even if your machine is really fast I'd consider setting Texture Quality to "Performance" as fps gains are nice, and IQ decrease is not obvious).

Note that you must manually activate the profile by right clicking on the nHAncer icon in the lower right of your taskbar. You only have to do this again if you have changed nVIdia driver control panel settings, so don't leave nHancer running in the background. [I don't even launch nHancer if I change driver level settings since I copied my RoF settings out of nvapps.xml and just keep that backed up and re-insert it as needed.]


There are plenty of screenshots in the other threads on this topic that show the change, but if you can currently run the sim with 8X AA or 16X AA then you can also run it using combined at 4X or higher, and this will work if you setup nHancer correctly.
