Anti Aliasing look so bad in every game

That's how it looks for most people. AA can only do so much. SSAA (SGSSAA) will do a lot to stop shimmering, but it also kills performance. Try to use DSR/VSR, that might help. Don't use FXAA, that will make it worse. You can try using blurry settings on your monitor, or push it further away.

The most likely cause to this is either FXAA or you just hyper focusing on something you didn't pay attention to before.

Your processor is ancient in the PC gaming world. 2500k is a Sandy Bridge (2nd Gen) Core product from 2011. They just released the 8th Gen last week, for reference.

I'd be willing to bet that you're being bottlenecked bad by the CPU.

AA can only do so much, and different types of AA doesn't work as well with certain things. The lines are about as good as you are going to get without going to a higher resolution. You probably changed something, and started focusing on things you didn't prior. You may also have sharpened the settings on your monitor, which draws more attention to sharp lines.

There is nothing wrong with that image. That is better than most games get.

It could be driver optimazation changes or something, who knows. I can't speak to what your gaming experience used to be like. I just know that you complain of a problem that persists across all games, which says "look at my hardware".

Your video card is prettty good and recent. Your processor (and that means your motherboard and your RAM, too) is seriously out of date. Like very.

Aliasing has nothing to do with the CPU. Only the GPU/driver, game engine, and monitor can make aliasing appear more or less obvious. And if you look at the image, there is nothing out of the ordinary there. He likely just started realizing that aliasing exists, or he adjusted some monitor setting that sharpened the image. Maybe he's sitting closer to the display, or increased the size of his monitor.

The CPU has nothing to do with aliasing.

I am more than aware of the fact that AA is GPU dependent, but you are assuming the original poster really knows what they're asking about...

Based on the EXTREMELY limited amount of information, and the very ambiguous way the question is asked "AA look so bad in every game..." makes it seem like maybe the OP is just experiencing performance problems and has decided it has to do with Anti Aliasing? I mean, the picture he posted doesn't look bad, but if you look at the parking lot lines in the distance they are a little wonky, but that's not an AA issue.

The reality is we're not given NEARLY enough information to diagnose anything, but I can say with CERTAINTY that if the OP is trying to play modern AAA titles on that setup, his CPU is a serious problem. For crying out loud, the Minimum Spec CPU for Grand Theft Auto V is an i5 3470, a whole generation ahead of this.

*Update - =804&cmp[]=822]https://www.cpubenchmark.net/compare.php?cmp[]=804&cmp[]=822
His CPU is a couple hundred points below the minimum spec CPU for GTA V. Regardless of what problems the OP is having, the CPU needs an update.

I know I've seen this same specs and question posted on another forum....Steam perhaps?

Issue, from what others posted there, appears to be the user and the user not understanding how AA actually works and the limits of it. I see nothing wrong with the picture.

My point was that you are talking about his ancient CPU, and it has nothing to do with aliasing. He recognizes what aliasing is, by the lines on the parking lot, so I was just trying to avoid going down this route further as his ancient CPU has nothing to do with his problem. Besides, that CPU isn't even bad for the most part, unless trying for high FPS.

Anyway, those lines on the parking lot are normal. When lines get really thin, and not perfectly horizontal, AA can only do so much. I have noticed that SGSSAA can help reduce shimmering, if he noticed shimmering, but his system certainly isn't good enough for SGSSAA.

I don't think the problem is my CPU, maybe windows 10 or idk. I didn't have that problem, the games used to look better, AA look like shit even in GTA SA, and if i max out AA in GTA V there is no big difference at all.

You have no idea what you are talking about. The 2500k is still a good gaming cpu, and would have nothing to do with any Anti aliasing issues.


OP: Check nvidia control panel, see if any of the AA options are forced off.

What AA do you have enabled in GTA?

Your picture looks perfect, as good as AA can do.

Did you change your monitor? The image is a perfect example of AA, but that doesn't mean your display isn't doing something, or it got bigger and more noticeable.

If you are noticing the dashed lines on the parking lot, there is nothing AA can do to fix that.

If you find that type of AA poor, don't use FXAA. Turn off FXAA, and turn MSAA to x4 if you can.

This isn't a matter of AA not working, but a matter of what type you prefer, and a lot of people dislike FXAA.

I have the same rig and had the same problem but discovered a fix (when it comes to GTA 5 anyway)

Go to Nvidia profile inspector (if you have it) and go to the GTA 5 settings. Change your "anti-aliasing behavior flags" from what it's set to now to "none" (it was set to some windows media related aliasing flag). After that your 2x in game aliasing should be totally reasonable.

It must've had something to do with either a gta 5 or nvidia update as people had no complaints until the past year or so, hence why I snooped around in settings looking for a fix for a seemingly unrealistic problem to solve. I run my game at 1600x900 with 2x AA and get a buttery smooth 60fps with the occasional 1% leaning into the high 40's, I absolutely hate aliasing and this has fixed it to the point where I can handle it, looks miles better than the previous ingame x8 AA.
