Jagged/Flickering edges in all games

AA did help be a tiny little bit but the jagging and flickering of edges is still there. Also in some games such as GTA4 there isnt even an option to turn on AA. I dont even think AA is the problem because a while back games were working fine

Although the pics you showed may not be examples, I've also found that a lot of the new techniques for adding details on objects/NPC's are immune to MSAA (multi-sample AA). MSAA will often fix jaggies around the outside of objects, but not within it's textures. Adaptive MSAA can help with those, and SSAA will also.

I don't believe your card can support MLAA, but that is a last resort for some of these console ports.

I'm sorry if I didn't make myself clear. It IS aliasing, and is fixed by anti-aliasing.

It is possible you had AA forced on within CCC before, and it's not now. That would explain the change, but that IS no doubt aliasing. Aliasing does move up and down objects as you change view or move. It looks just like the pictures you showed.

its still the same wether i force it trough ati tray tools or not. also i play on maximum res that my monitor supports.

You know there is something i have just thought of. monitors sometimes have a "sharpness" option. maybe someone has turned this up which would make your problem more noticeable. reset your monitor to defaults. Also go to CCC and turn anti aliasing to 4x and multisampling on also (not too familiar with ati's control panel so look for something similar) this is what you are getting http://www.gemaga.com/2007/12/28/t [...] the-hd-era it is definitely aliasing.

that's creepy.

you mean before even with gta4 not having any AA option at all it was working fine? you mean aliasing artifacts were non existent before.

set CCC to factory defaults. uninstall whatever 3rd party gpu software you have

i had a 4870 before, and i believe gta4 was the sistine chapel of aliasing artifacts. i would've make a screenshot of it with a gtx460 with much the same visual aliasing but i'm quite lazy to reinstall the damn game.

In terms of getting AA to work with GTA4, I can't find any way to force it by google search. The games engine doesn't allow it to work in Dx9, only Dx10, and they didn't make Dx10 available.

What other games are you having issues with?

are you sure the resolution is turned up? im not talking about just in windows desktop, but in the game settings also. really, if you have tried everything that has been suggested i dont know what else to do. Setting correct native resolution and turning on AA should fix the issue, especially since you have tried reformatting different os's and drivers. maybe there is something wrong with the vid card???

Just cause 2 put gta 4 to shame in every possible way and proves beyond all doubt that gta 4 is badly optimised for pc.

@OP.I think the cause of your trouble is probably the driver.It has happened many times with nvidia drivers on my gtx 275 that upgrading the driver results in some more aliasing in games.This happens generally due to the fact that the ati/nvidia try to improve performance in games and to do this sometimes the image quality gets a little degraded.Try out previous drivers on your 4870 and see whether that helps.
PS-Instead of testing gta 4 test just cause 2 with 2XAA and 16XAF because even at 2XAA there are absolutely no jaggies in the game.

What you are seeing is not a "problem" really. It's just now more visible. Now that it's visible to you, I doubt it'll be possible to go back to what you considered "normal". As someone else said before, perhaps you made everything sharp on the monitor, so the "problem" is more visible to you. Unfortunately, now that you are looking for it, it'll be impossible to ignore, even if you some how got your monitor to show it the way it was (probably blurry).

As I said try reverting to a older driver and if that doesn't work just ignore the problem and enjoy the game.Games are meant to be played and not looked at.This problem you are having is nothing to do with the video card failing.If your problem is only gta 4 remember that GTA was never about graphics but about gameplay.I still play gta san andreas and inspite of its aweful graphics I enjoy it and the funny thing is that with anti aliasing enabled in gta san andreas it actually looks better than gta 4

Like we've said many times, that is aliasing. MSAA can fix the "problem". MSAA will not work with GTA4, but it will work with crysis, and probably some of the others.

Another note on aliasing. In Crysis, aliasing won't remove all jaggies. It won't work on the foliage or on the interior lines of objects, like even on the gun. It will work on the outside edges.

sorry to revive this, but Im having this problem too, I know exactly what you're talking about. It's not that anti aliasing is off or on, that is besides the point. The issue is that the jagged points on curved shapes actually flash and appear to move up and down. It's almost like the lighting engine is being screwed with by the jaggies.

Again, I'm well aware of what AA is and how it should and does work. This may be an AA related issue, but something wierd is going on- definitely not just normal & expected jaggies.

Holy ***, I am sooo tired of this!
I have exactly the same problem, and it appeared few months ago out of nowhere! I've tried everything, no result. This really makes all games inplayable, it is impossible to bare all this flickering.
