THIS GUIDE IS ONLY FOR DX9. The in-game AA setting even at max level is not really statisfying, with many jaggies remaining. I hate jaggies with a passion. So I looked for a way to override in-game AA settings with AA settings from a custom NVIDIA profile for rFactor2.exe, to force Sparse Grid Supersampling combined with strong AA. There's a trick to have it working that I did not find immediately hence this howto. 1. First, if necessary, download and install NVIDIA Profile Inspector 2. Now create a custom NVIDIA profile for <install dir>/bin64/rFactor2.exe. You can do this either in the NVIDIA Control Panel, or in NVIDIA Profile Inspector ("Create new profile", then "Add application to current profile" icons) 3. Once created, load the rFactor2 profile in NVIDIA Profile Inspector 4. That's the trick for our custom AA settings to be applied: set "Antialiasing compatibility" to 0x40 5. Now in the Antialiasing section set these: Antialiasing - Mode: override any application setting Antialiasing - Setting: 8xQ Antialiasing - Transparency Multisampling: Enabled Antialiasing - Transparency Supersampling: 4x Sparse Grid Supersampling That's for 8xQ / 4x SGSS which provides the best AA but it is really taxing, so you will have to adapt it to your hardware. On my GTX 970 I have to lower it to 8xQ / 2x SGSS for fps to remain acceptable, although with Automobilista I can crack it up to 8xQ / 4x SGSS and still maintain constant 60 fps @ 1920x1200 because its rendering engine is less taxing thus more headroom. 6. Make sure "Texture filtering - Driver controlled LOD bias" is set to "on" 7. When done do not forget to save with the "Apply Changes" button 8. In the rFactor 2 video config settings set "Anti-Aliasing" to "None", and if you have FXAA enabled I suggest to disable it as well because it is not really needed with high quality AA and will make the final image more blurry (less sharp). (optional) 8xQ / 4x SGSS will definitely push your GPU. If it is a 1080 Ti, it should not be a problem but if you need to squeeze more of it, I suggest to overclock the GPU with MSI AfterBurner. This is out of scope for this howto but well documented online Also, in my experience, 8xQ / 4x SGSS provide such high quality AA that it is not necessary to combine it with NVIDIA DSR. There's also 8xQ / 8x SGSS for ultimate AA but it is even more taxing (halves the fps on my system).
