    I will test that, thanks.

    OK so NVidia Inspector has some pre-stored bits: 0x00000045
    I'll test them and the ones you provided.

    EDIT: I think the one you offered is better since it doesn't affect the FPS much for me at least.

    Must be some driver related issue for me then (using 441.66)

    This is what it looks like for me.

    I tried both 0x400000C1 and 0x000000C1.

    Try disabling bloom in the Video settings maybe. (Fullscreen, borderless,windowed?)
    Is in game MSAA still turned on when you are forcing AA? Any mods?
    Also try 8xSGSSAA. Once in a while there will be a game that has an issue depending on what sample count you use.
    What do your inspector settings look like?
    I'm on 441.41 (But on my W7 drive)

    I don't remember but can you share save files from Hl2 and I could try the same spot?

    Well i reinstalled the driver as i was using the Clean Version. I switched back to the original one from Nvidia.

    Seems to be sharper now. I do know SGSSAA Blurs a bit, maybe i just never noticed it before.

    Incase you do want to try out the save --> http://www.mediafire.com/file/v9bmir64fv6xo6t/Sandtrap_Save.zip/file (Requires Half-Life 2: Update)

    It's possible HL2 is causing the issue. Are you able to test without it too? (Real vanilla Hl2) I would also attempt to turn on the AA fix. As sometimes that can be the difference between soft output or sharper output.
    Alternatively you could attempt to use the flag with a 5 on the end of it as that will skip the primary flip chain and will either result in sharper output, AA not working at all or the UI not being left alone. Or you could add a slight sharpening pass.


    It really just looks like a bloom shader conflict or something. On certain surfaces it's very visible that it is doing what it is supposed to do. (The guard railing to the left for example and then also the rock faces to the left. HL2 often has an issue with a large amount of high frequency aliasing present in it's textures and how it renders them. So it's taking care of that properly. The power lines aren't being handled right. And there is a slight layer of softness being added to the image because of what I assume is a shader issue.

    Depending on what post processing shading is going on in a game it can cause a conflict with SGSSAA and cause the output to be softer than it should. There are sometimes ways around this, by disabling certain post processing settings.(Or the AA fix will help)
    For example, In Hitman Contracts and Hitman Blood money, the Bloom shader makes the image a little bit blurrier. Turn it off and things are 100% sharp though you run into the limitations of the default MSAA resolve where there is still a lot of visible aliasing as a result. (As shown in my HL2 comparison above.) But some people prefer that. However you can really work around this with a reasonable amount of sharpening and get a better middle ground. I played through Blood Money with the blur issue and some mild sharpening because I enjoyed the hazy look the shaders added and overall pixel quality was better.

    Looks like it's an issue with Half-Life 2: Update, even with all settings low the AA is blurry.

    But i swear it wasn't like that months ago when i played it.

    So either something changed in the Nvidia Drivers or the Update Mod changed.

    I give up now.

    Hello guys, I have a problem with Mass Effect 2. It's just impossibile to activate any kind of antialiasing. I tried with Nvidia Inspector by adding the the application "ME2Game.exe" in the Mass Effect 2 profile and typing 0x080100C5 or 0x080000C1 in "antialiasing compatibility". I changed "antialiasing mode" in "override any application setting", "4x [4x multisampling] and "4x Sparse Grid Supersampling".
    It just did't worked. How can i activate the AA???

    It's entirely possible something they changed in an update.
    You could also downsample on top with a low smoothness value with DSR to help even out the sharpness. Or you could add a sharpening pass via the new driver option. Or even your monitor.
    Alternatively you could try seeing if using the Enhance Application setting makes a difference. Or you could force/enhance with a Hybrid Sampling Mode. For example 8xS, you'll get minor supersampling and 4xMSAA, you could also add TrSSAA on top of this or SGSSAA too. (Which may help even out the blurriness) . There are quite a lot of possibilities to get to the end game you want with the performance level you want. You just need time to test different things with some trial and error to find the middle ground you find acceptable.

    The new driver sharpening does work with forced SGSSAA, I am testing it currently with Killing Floor. It cause the screen to shake and wobble at first. But after a minute when the game has booted up it goes away.
    There's two settings in Inspector for this
    "Sharpening Filter" (0 off, 1 on)
    "Sharpening Value" (Default is 0x00000032 , values up to 0x000000FF) Default value is a bit too strong in the small amount i've tested.

    Pardon this really odd reply but I plan on playing Prototype down the line and the bits for Proto2 would work with it just fine?

    I don't own either game so I can't test for you sorry.

    Regarding the HL2, the same issue that is present in BM, is also present in all HL2 games. That is when there is certain type of light source, everything inside the light gets aliased. I noticed it in Episode Two, when Vortigaunt was holding larvae extract:

    Not an uncommon thing with games that use different buffers for different effects.
    But I don't see what you mean in that screenshot. You must mean temporally the effect happens where there is crawling/flicker and things look lower res and not anti aliased when passing under these sources as there is movement.
    This is also really common when some buffers are not affected by any kind of AA. (Dead Rising 1 DoF, Bloom in Revelations, bloom in Deus Ex Human Revolution, the highest quality DoF effect in Human Revolution, the DX11 DoF in Crysis 2)

    Take this shot for example. Looks perfectly anti aliased still. But the bloom buffer is unaffected by AA and is tied to a fractional amount of the main screen resolution. As soon as there is any movement, that low res buffer becomes immediately apparent and there is a lot of visible shimmer/crawling of the light effect. Which is present on all light sources with bloom in this game. (Which could be helped by higher resolution. But this game is res locked to 1440p max)

    I see. Well, I just thought it might be interesting to note it.

    Yeah sure I can make a note on the entry for HL2. Do you have any other screenshots of this too I can see? I'm curious.
    You also mentioned BS? What is that?

    Game doesn't need any bits.
