Does your ATI card not support eyefinity? If it does, get an active Displayport/DVI connector for one monitor, and use the 2 DVI connectors for your other monitors, and this may solve your problems.Bill

The vsync issue remains regardless if you use triplehead2go, eyefininty or a single screen. I've tried them all.

what about this external frame limiter praised here somewhere in the forums?! dunno the links for thread now.

I guess you mean FPSLimiter. Unfortunately, simply limiting the FPS below the refresh rate will not completely cure the horizontal tearing.

Still does nothing to the VSync though and without that you are still going to get wiggly lines whatever the frame rate......

Good to see other folks here that own ATI cards..I recently upgrade from my XFX Nvidia 8800GT to the XFX ATI 4890. Overall I get better frames and am now able to run FSX in 1960x1080 resolution getting very good frames. My one gripe is that I get pretty heavy stuttering when I have the default limiter set to 'unlimited' while flying in the Tongas Fjords X addon. The stuttering comes out in areas where there is a great deal of tree autogen I think. This was less of an issue with my Nvidia Card but prior to replacing that card, the newest drivers where also causing stutters.Are there older drivers that do a better job with the autogen for the 4890?Thanks,WallyIntel Core i7 950 (overclocked 3.8 Ghz)XFX Radion 48906 GB Memory

Is the screen tearing only affecting a certain range of the product line? I've looked through the two links that Hamish posted and it looks like it is a problem in the newer lines of ATI cards.I'm now running FSX on my laptop with a ATI Radeon HD3450 running on a system with Windows 7 64bit. I haven't noticed any vsync issues yet. I'm running a lower restricted FPS, that might maybe...for some reason I feel helps. :( I'm still dailing in the graphics for my laptop, but I'm surprised how good I can get it so far.

Irregardles of whether it's Nvidia or ATI, once you tune FSX to your system, the MILLION DOLLAR mod (to increase performance, and possible get rid of stutters and tearing) IS, and will ALWAYS be, the AUTO GEN SLIDER. Period. Sorry to bust your bubble.You set up your system, Bios, Motherboard chip driver, Video card drivers, then overclock, add Nhancer (setting FSX and Global to the same values-then put it away-this prog ONLY helps with visual quality, not performance) and then you go get FPSlimiter, set to 30, with FSX frame locked to unlimited. Then you get tearing. The fix? You got it! Auto Gen SLIDER. That's life! You can't have everything. What you see is what you get.Vsync? FSX with i7 and 4870 card? Will NOT help performance if you turn it off-nuff said. And with i7, W7, SP2, FPSlimiter won't do much if anything. The Auto Gen Slider will do more. But, be sure your 'Global Texture Resolution' slider is MAX/100%. Finally: clouds WILL hurt performance (no way around that).CBNapamulePS: This is 99.9% from NickN's 'Setting Up FSX and How To Tune It'. (I ain't that smart-but I do understand what I read-and then write it down-hehe).

Vsync is not a good idea for FSX because its frame rate varies so much, and once you turn it on, you will see some lag from your mouse and controller.

gman! - My man :)Why do you continue to post pure b*ll about FSX and the various tweaks?No Vsync?What do you suggest then?What was the last miracle cure - 0 bufferpools - if i remember correctly...Please put a lid on all the sudden tweak-impulses you apparently get from somewhere...An "FSX psychic maybe"? LOL!

I'm glad you're having such a blast with your autogen slider, but you have obviously not understood the issue that is being discussed here. It has nothing to do with performance. (Actually, increased performance will in a sense make the problem worse).

People with the 5870 and other affected cards are discussing this issue because the lack of vsync makes FSX look absolutely awful. If you haven't experienced this yourself I'm not sure what you're trying to achieve here. Telling us that "Vsync is not a good idea" simply does not help.And before someone (who hasn't experienced this particular problem) tells us for the 2134:th time that limiting the FPS within FSX or using FPSLimiter etc is a good workaround for the lack of vsync... no it's not. Forcing vsync makes the tearing go away, FPS limiting does not. That's not how it works.

First of all the 0 bufferpools was not my suggestion, people need to learn how to read and learn which source it was from. I have never told anyone to set bufferpools to 0 because I know for a fact that it causes problems especially on my PC. Um, can you tell me which tweak I have posted that is bull? The only tweaks I have posted from memory are the bufferpools (which I said NOT to set to 0, but rather a value lower than 1MB) so people would not get invisible textures or black/white screens anymore and many people have said it has fixed their textures disappearing on aircraft. The other tweak I posted wasn't even a tweak, one was a guide to help people install FSX correctly on Windows 7, in which I said, there are no need for CFG tweaks, only bufferpools may be nessacary. Then I posted how to add scenery to Windows 7 because of a Windows Explorer incompatibility, and last, I posted a guide on how to stop fatal errors in FSX in Windows 7, and I'll post links to all so you can re-read them closely. If you find a post where I, not someone else or someone in my thread, has posted a "miracle tweak" send me a link. The only tweaks I have stated or ones that are Tileproxy specific which are to get tileproxy running smoothly and ONLY for tileproxy and was ONLY posted in tileproxy posts. Other than that the only tweaks which I have condoned are bufferpools for everyone.Here are links to all my posts and I hope you read them carefully.http://forums1.avsim.net/index.php?s=&...t&p=1671451http://forums1.avsim.net/index.php?s=&...t&p=1692080http://forums1.avsim.net/index.php?showtopic=265677http://forums1.avsim.net/index.php?showtopic=271292http://forums1.avsim.net/index.php?showtopic=267300&hl=-------------------------------------------------------------Its my opinion but the lack of V-Sync in FSX does not make it look awful to me. Maybe its because of my card, software, or because I'm on one monitor, or it could just be me. When FSX tears for me it is not dramatic in which one half of the screen is moving and the other half isn't even moving at all. Even though it tears it is only minor and it is still smooth. V-Sync is not for FSX and that is why the developers never put an option in-game for it. V-Sync first of all is supposed to make the vertical rendering stay in sync with horizontal rendering to stop tearing, but when you do this, the computer must wait for the vertical buffer to finish before it can draw the next frame. This causes lag when you input anything, and the reason WHY it tears is so the game will stay smooth and not lag. If you can please post a video preferably with a video camera in which we can see the problem you are describing.

I can't give you any links, but I have read that Matrox triple Head 2 go has had issues when used with an ATI card, and has been that way since the beginning. It is actually recommended to use an NVidea card. I have also read that Matrox do not support Win7, and have no plans to do so in the future.Does your ATI card not support eyefinity? If it does, get an active Displayport/DVI connector for one monitor, and use the 2 DVI connectors for your other monitors, and this may solve your problems.Bill

Matrox is supporting the digital version of the th2go, not the analogue version.

I'm a little confused, I'm running FSX on a 5870 and I haven't seen any screen tearing issues at all. Mind you I'm not using Track IR or Eyefinity on my setup, but I'm considering going to that eventually.

Thats whats confusing me! Most of the time I don't get tearing, and I have my slider set at unlimited and refresh rate at 75Hz. I never thought of this before but perhaps renaming the fsx.exe to a game that supports vsync like UT3.exe, HL2.exe (Unreal Tournament 3, Half-Life 2) can enable Vsync since Catylst Control and Forceware have specific settings and profiles for each game?-------------------------------------------EDIT: I'm testing the suggestion right now, and to the below post, if you don't already have ATiTrayTools (Search the Video Card Forum) you should download it. You can control the specifics of the supersampling, and also try 4xAA EdgeDetect or try 4xAA Narrow and Wide Tent. Play around with it a bit and you might find settings you like :(
