    When doing these settings with inspector etc, do you have "let application decide" in nvidia preview setting?
    Sorry for the noob question :unsure:
    What would you suggest for my cards? 660ti's 2gb

    I'm pretty sure you want "Override any application setting".

    I've got two 780s in sli. I use 4 x MS and 2 x sparse grid supersampling. I get very good performance with that and a nice picture. There could be more optimal settings than that though (I'm no expert).

    Billy, for SGSSA to work properly, it has to match the MSAA factor, so if you're using 4xMSAA, you will need to use 4xSGSSA, if you don't it can cause blurring.

    For MSAA, in the Nvidia control panel you can either enhance the application setting IF the game supports MSAA which in this case Formula Truck does. If you select override the application setting, it doesn't matter what MSAA setting you use in game, the Nvidia control panel will override that setting. Its generally preferred if the game supports MSAA to use enhance application setting, but override will likely work just as well.

    What resolution are you playing at? And how much does aliasing bother you? SGSSAA does an amazing job of cleaning up aliasing in this game and GSCE, but it does come at a performance penalty so I guess If aliasing really bothers you, I would use 4xMSAA+4xSGSSAA and then dial back the in game graphics settings to a framerate you're happy with.

    Running triples at that resolution, you will not likely be able to use SGSSAA without a pair of GTX 980s. You are likely going to have to settle for a lower AA setting unfortunately.

    Thanks, Blkout, for your suggestions on this.
    I had had the settings at 4xMS and 2xSGSS. After reading your recommendation I tried 4xMS and 4xSGSS but the performance was quite a lot worse (losing 20% or 30% of my fps). So I've put it back at 4xMS and 2xSGSS (and, as far as I can see, there's no blurring at those settings). I appreciate the tips from you though.
    In fact, I'm quite happy with the picture and fps that I'm getting but it's always worth seeing if you can get even better.

    I am, however, getting quite a bit of micro-stuttering on some tracks. If you had any tips on remedying that, they'd be most welcome.

    BTW, I know about this tip (from Reiza's Formula Truck 1.25 update post re the .PLR, file):
    Shadow Updates="127" // Static shadow updates per frame (Shadow Updates * Sky Update Frames should exceed number of static shadows on track)
    Sky Update Frames="8" // Frames between sky and light updates

    Change it to:
    Shadow Updates="8" // Static shadow updates per frame (Shadow Updates * Sky Update Frames should exceed number of static shadows on track)
    Sky Update Frames="150" // Frames between sky and light updates

    I'm wondering if the micro-stuttering is because of the added (since 1.25) time progression. In GSCE turning off time reduces/eliminates micro-stuttering. But I can't find any way to turn off time progression in Formula Truck.

    Not sure if it's the same thing Billy but when I was looking to stop stutter (it didn't seem to help) I think I changed the Quick and Multi TimeScaledWeather from "1" to "0".

    SLI is pretty much broken in GSC, rFactor 1, etc. unless you play in 3D, then not only do you getpositive SLI scaling, but it's almost perfect SLI scaling. Almost 100% (double) the framerate.

    If you pump in a lot of super intense forms of AA from the NVidia control panel / Inspector then that may be able to hide the broken SLI of the game itself because that should be helped by SLI regardless of the game itself's good/bad SLI support.

    I'm now using Nvidia Inspector with the recommended settings by Blkout the only thing now is I'm using a single card.
