    32C5 4xSG gives me HUGE framedrops, even in menus (like 30 fps), gameplay hovers hovers over 20 fps :wanker:

    Really? That's bizarre. I expected it to give me big performance problems, because shader supersampling usually does. But in a few games, like Pinball FX2 it doesn't. And it didn't for me here.

    What do your OSD readings show?? Max GPU usage?

    Something afoul. Resolution you are playing at maybe?

    SSAO turned on? (This tanks performance with SGSSAA)

    OH OH. It does, and it does so even worse with ShaderSSAA enabled.

    I turned it back on with 32C5 and I get the same drops you do. I will add that note.

    Yeah, its SSAO that tanks perfomance, but i still don't get why? Even during FMV video and main menus, that's crazy :) Maybe HBAO+ injection will work better (if it possible of course)

    you found another flag ? greeaat cant wait for trying when i get home :)

    Update:

    tried 32C5 result in this flag is stutter and high performance drop when using 8xSGSSAA on my system(980TI,2560x1080),but 4x is fine.32C5 better in motion no shimmering on the walls, but a little bit blurry than C1 even with using AA fix.

    SSAO High and 8xSGSSAA is fine on C1 but with 32C5 is stutter. for personal taste i'll going back to C1 with AA Fix ON

    There are no AA compatibility flags that affect OpenGL.
    The only options are to enhance ingame MSAA (if available) with TrSSAA, or try and force MSAA+TrSSAA without a compatibility flag set (0x00000000).

    I know "F0C1" is mentioned in the OP for this thread, but that is pure BS.
    This AA flag is the supersampling MSAA mode from STALKER, and only has an effect in DX9.

    That's fine. 32C5 works better for 4xSGSSAA. I don't imagine it would help 8xSGSAA. C1 4xSGSSAA was very lacking but 8x was fine.

    Here's an easier to see comparison for 4x
    http://www.screenshotcomparison.com/comparison/206932
    http://www.screenshotcomparison.com/comparison/206936

    It does trim out a hair more high frequency information. (It's way blurry without the 5 at the end. 5 skips the primary and makes it sharper. But also skips fixing the scaling of FMVs that are broken. Where as C1 would fix the FMV image scaling)
    But it's barely noticeable at 4x and the better reduction of aliasing is much worth it.

    Which reminds me that, that needs to be removed lol.


    Anywho, i've heard some people having luck forcing SGSSAA in Cemu just by setting MSAA and TRSAA. Or if Cemu has an MSAA mode. Enhance it.

    Anything for Path of Exile DX9 and DX11?

    Bits 0x004040C1 and 0x004012C1 no longer is working.

    edit/

    DX11 version has already MSAA build in the game.

    I won't be home for a few hours, but I was wondering if you know/think that this TXAA enhancing method would work for GTAV or not. Seeing as it works awesomely with Blacklist, and both of these games are DX11 with TXAA support I figured it might be worth a try. What bugs me most in GTAV is the nasty looking power lines, fences and all the other transparency/temporal sort of things.

    It could work, but from what I recall seeing from someone else. It doesn't work all that well with GTA V.

    Your best bet is to use TXAA+Maybe FXAA or SMAA on top (Will catch hard edges it misses)+DSR (Adjust smoothness slider to your taste)

    Enhancing ingame TXAA with TrSSAA or SGSSAA does very little in GTA V, and is a complete waste of performance IMO.
    And even with native 3840x2160 + 2xTXAA I still see plenty of shimmering and aliasing in motion, however general IQ is of course very nice.

    In a similar way is Max Payne 3 DX11 MSAA also close to useless when enhancing.
    5760x3240 (3840x2160 with 2.25xDSR) combined with ingame FXAA is definitively the way to go in MP3 on my system.
    DX9 SGSSAA is of course decent but then you are forced to using only SSAO instead of HDAO, and there are these ugly line artifacts in shadowed areas.
    Not related to the AA fix though.

    0x000012C1 works for forcing SGSSAA in Hitman Contracts. Don't see it in any of the lists out there. AA Fix is a must though.

    But is a custom AA profile even needed for such an old renderer?
    Did you try with just "0x00000000" or "0x000000C0"?

    0x00000000 doesn't work for sure.
    0x000000C0 does and the result is similar to 0x000012C1.

    In both cases only SGSSAA works, MSAA doesn't.

    Couple of shots with SGSSAA via 0x000012C1 bit:

    https://abload.de/img/hitmancontracts_2017_w8qn9.png
    https://abload.de/img/hitmancontracts_2017_5iqux.png

    It's important because the only other AA option for Hitman Contracts is driver's FXAA (which you can't capture on screenshots) since the game doesn't support MSAA and it doesn't rescale HUD which makes DSR pretty much unusable.

    Is there known compatibility bits for Dragon Age 2? I looked through the spreadsheet but didn't find any and DAO bits didn't seem to work for it.

    0x00000040. Or 41. would probably work for MSAA/TrSSAA

    Would you mind taking an A/B shot of C0 vs 12C1 just to make sure there is no quality difference? I added it to the list already. But would be nice to see.

    DA2 was DX11 As far as I know. Or DX10. Either way it's impossible.

    The in game MSAA samples aren't so great

    Line artifacts

    [​IMG]

    Turning off AO seems to have gotten rid of the lines.

    [​IMG]

    Heavy (33%) performance drop with shader effects on.

    All effects on

    [​IMG]

    All effects off

    [​IMG]

    Needs AA fix to avoid blurriness as much as possible.

    MSAA samples go kaputt whenever geometry overlaps in front of a transparency.

    With 4xSGSSAA this is as low as I could get my framerate to go on my 1080 Ti in the starting area with DoF, AO and Motion Blur off.

    So, I am assuming this is Enhancing the in game MSAA?? (Need to know for reference.)

    Also, these shots show the weakness of the standard MSAA box resolve I think as clearly could ever be shown. Where SGSSAA is perfectly integrating (effects it has problems with, withstanding) with the rendering. But the box filter is holding back the quality of the final effect.

    (Halo Wars is another example of this to the same degree as well when enhancing).

    Yeah I'm just using the in game MSAA.
