    That's great, would you mind just making a post for Grim Dawn including your prior comparisons and this? I am all for making it known that it might be impossible to force SGSSAA or that you don't need bits for MSAA and that there are other methods available.


    ALSO:

    Would you mind trying 0x00000041 for SGSSAA?
    Would you also try enhancing the in game MSAA with SGSSAA? (No 8xMSAA needs to be real MSAA not CSAA if you try 8x)

    Also: Forcing SGSSAA without bits is blurry. Try a -1.5 LOD bias for 4xSGSSAA and then try sharpening it with SweetFX a bit maybe. It might be usable too.

    You can also try enhancing the in game MSAA with an HSAA mode, like 4xS Enhanced + 2xMSAA+AtC in game + 4xTrSSAA

    Another DSR scale to try would be 1.5x1.5 instead of 2x2 to gain some performance. You might wish to try using Driver on top of MSAA/TrSSAA with DSR as well. It can help out a bit and usually oversampling negates blurring effects. (As well as a slightly lower Smoothness setting. Like 1.5x1.5x+4xMSAA+2xTrSSAA+AtC+Driver FXAA @25% Smoothness)

    Once you get to other parts of the game, performance is better. The Opening scene is really bad. But the AA fix adds no quality (Makes edge quality worse).


    Here's a couple comparisons. One at 1080p and one at 765P both with 8xSG
    http://screenshotcomparison.com/comparison/160227
    http://screenshotcomparison.com/comparison/160228

    This is on a 980 mind you. Not great performance.

    I think using MSAA +In Game FXAA(DoF=True must be set)+Downsampling will yield the best results in DX9.


    Using 20C1 for SGSSAA produces perfect AA (Bloom/DoF still flicker a bit) but it's soft (-lod and sharpen would help) and the performance penalty is a bit steeper.


    Alternatively disabling the Post Processing entirely with DoF=False will also gain some performance back. But you lose all PP.

    SSAA in the new Tomb Raider doesn't look very good. They just seem to be doing a standard OG with a bilinear/box resolve without even combining it with FXAA at least to help with high frequencies and edge quality.

    http://screenshotcomparison.com/comparison/160333 (Meanwhile the water reflections here are a blurry upscaled mess regardless.)
    Not my comparisons.

    It doesn't look good considering the performance penalty i've seen in reviews.

    GUILTY GEAR Xrd -SIGN- uses typical UE3 bits? Game aslo uses dx9.0..

    Assuming a DX9 title with good in-game MSAA, is there any perf/IQ difference between enhancing it with SGSSAA, or overriding and forcing MSAA+SGSSAA? Or do AA compatibility flags only work when overriding?

    Does anyone know compatibility bit for Sims 3 and Sims 4 ?

    It probably does. Try 0x080010C1
    Enhancing almost always depends on the in game AA's quality and implementation. (Look at the example of Grim Dawn on the last page)
    The only exception I know of is Fear 2.

    0x000000C1 is a place to start.
    0x00000041 is too.

    Glad it could help. Also: Make sure the in game AA is disabled if it has FXAA like most other UE3 games.
    Not sure what problem is. Need before after shots

    Sadly i can't turn it off from game options (it has SMAA, MLAA and FXAA), maybe *.ini tinkering is needed.

    Oh dear lord... it might be tied to all post processing.. so you might end up being stuck with FXAA forever on if you want things like Bloom or any other PP.
    And this doesn't happen without AA? Looks kind of like pop-in.

    Ok, so would you mind taking a screenshot of your Inspector settings first before I start offering some suggestions? Just to rule out any human error.

    OK. Your LOD bias is WAY too big for starters. Dial that back to -1.00 for 4xSGSSAA.

    Try that and then try turning on the AA Fix.
