Anti-Aliasing doesn't work anymore after GPU switch

[Lange_666]

Story: Needed to test a videocard. Swapped out my GTX1080ti, put in a GTX780 to test, didn't work under load (what i was expecting), removed it again and put back the 1080ti. Since then i don't have AA in DCS (DCS only, other games are fine). No matter what setting i try, there's no AA.

In Nvidia Control Panel the remove button for the DCS profile is grayed out, so that's not an option.

Any other idea's are welcome.

Hi. Maybe the game doesn't detect your GPU properly anymore. Please attach your dcs.log file along with your dxdiag log.

Thanks. DCS seems to properly recognize your 1080Ti.

Have you ensured your "Antialiasing - mode" NVIDIA setting for dcs.exe is "Application controlled"?

 

I'm not sure shaders have much to do with antialiasing, but just in case, empty these folders:

• C:\Users\username\Saved Games\DCS.openbeta\fxo\
• C:\Users\username\Saved Games\DCS.openbeta\metashaders2\
• C:\ProgramData\NVIDIA Corporation\NV_Cache\ (you won't be able to remove all files because some of them are used by other programs like Chrome and Firefox)

Yes, AA-mode is (was) set to Application controlled.

Shaders were cleared before the update to the latest Beta which i did yesterday.

NV Cache: removed those with a yesterday's data tag.

Tried resetting your global defaults in the NCP?

I've compared our dxdiag logs (I own a 1080Ti too): all seems OK.

Try what @glide suggests.

No but i took a more drastic approach by removing the NCP DCS profile (through nVidia Inspector) and making a new one. All seems OK now.

Thx both for the help & hints!

In the end this didn't work. It seemed to work but i did only a quick test because of lack of time. Yesterday i had some more time on my hands so it still didn't work. Syria map, Haifa airport i noticed way to much shimmering then it should with MSAA x4 so i tried some other values, let the NCP take over, no joy at all. Both stable an OB had the same problem (but i use to copy my settings over between them). In the end i removed the options.lua (and the presets) and started fresh, MSAA came to life immediatly. All works again now.
