recommends using SGSSAA
Dark Souls 2 PC tweak guide | PC Gamer
However, there is another, even better option (than downsampling) for those of you with Nvidia graphics cards. I discovered a “compatibility flag” which works with Dark Souls 2 and enables the use of any level of SGSSAA (2x, 4x and 8x). In order to perform this tweak, you need to get Nvidia Inspector and set up the Dark Souls 2 profile as shown here:
It may be slightly confusing to select numbers associated with other games such as Diablo 3 and Demigod here, but all it means is that what Dark Souls 2 does in regard to rendering is similar enough to what these games do for that particular “hack” to work. Here are the specific steps you need to perform for Inspector-based tweaking in Dark Souls 2 (as annotated in the image):
Better Image Quality in Motion
- If it is not already there, add “darksoulsII.exe” to the list of executables associated with this profile, by clicking the icon with the small green “+”.
- [Only if you want to use HBAO+, see the next part of the article] Enter “0x0000001F” in the “Ambient occlusion compatibility” field.
- Enter “0x004412C1” in the “Antialiasing compatibility” field.
- Select “Override any application setting” as the “Antialiasing – Mode”, and select your desired level of SGSSAA in both the “Antialiasing – Setting” and “Antialiasing – Transparency Supersampling” fields. Higher levels are higher quality, but also cause a larger performance hit.
- [Optional] If you want to force full anisotropic filtering on all textures in the game, you may do so here.
- [Only if you want to use HBAO+, see the next part of the article] Set “Ambient Occlusion Setting” to “Quality”.
I previously described the drawbacks of the post-processing antialiasing method used in the game, but concepts like temporal stability and sub-pixel structures might appear quite abstract without an example. The following animation shows the difference on some swaying grass, which is an example of a thin structure in motion. To make the distinction more obvious, the image is scaled by a factor of 2 in both dimensions.
Note how the in-game anti-aliasing does not work well in this use case, causing flickering and image instability, while 4xSGSSAA handles the situation perfectly. AMD users need not fret, downsampling from a sufficiently high resolution can achieve similarly good results.

I believe downsampling is equivalent to OGSSAA.
