Hey AllHow does ATI HD5870 Eyefinity 6 (4-5 monitors) performance compared to GTX470 with a Tripelhead2go (4 monitors)And will a Tripelhead2go decrease my performance!!??

Any body??!!??

My understanding of TH2G0 (and I welcome correction if I am in error) is that it simply spreads whatever you have on your main monitor across 3 monitors. This being the case, your computer doesn't have to work any harder than with one monitor and frame rates are unaffected. But you are still seeing ONLY a single VIEW, albeit now much wider, but with top/bottom trimmed off to fit the triple wide format.It has been my understanding that Eyefinity allows you to display MULTIPLE FS views- hence you gain a much wider Field of View (FOV).You can also display 2 different views by using the two ports on the video card to drive two monitors or even better use a second card to drive a third monitor/view. But be aware that each extra VIEW will reduce frame rate somewhat.The standard FS View spans a very narrow 45º. Compare this with normal human FOV vision of 180º- which you need for a PPL.So any system that can display MULTIPLE FS VIEWS is a worthwhile venture!(Panning and/or Zooming In/Out to increase FOV is, I believe, not acceptable for FAA approval of a pilot training device. Zooming, in particular, has a very negative impact on distance perception- which in turn affects speed perception.)Alex Reid

Okay so you recommand the HD5870? when i running with 3 monitors to window and 1 to PanelAnd i will not play with more views, but with a larger window FOV when i running in 2D panel (I allways does that) (120-140^o)Will that reduce fps with more than 5-10 %Thank you for your reply

ATI cards are not great for FSX. They don't do anti-aliasing well, and drop frames in clouds. If you are going to buy a card + TH2GO, you might just be better off getting two Nvidia cards and using surround gaming, that would be my recommendation. Altho I don't know if you can use and additional (4th) monitor for panels with Nvidia surround.If you want a one card surround solution, then ATI would be the way to go.

patrickbc- It is multiple views that puts an extra load on the CPU: each view-frame has to be processed in turn by the CPU before it is rendered by the GPU.My experience is that a second view will impact FPS by about 30% and a third view drops it to about 50%.I set FS9 sliders to achieve 30-50 FPS with only one view. That gave me a FPS of 15-25 with 3 views being displayed.If you take the trouble to adjust the angle of the outer views to precisely compensate for the bezel width, you create what your brain sees as a single very wide view. Only 1/3 of this image is being updated at any moment- 2/3 of the whole is always frozen. Or phrased another way, 2/3 has an infinitely HIGH frame rate!! As a consequence, a displayed frame rate of say 15, is as smooth to the eye as 30 appears on a single monitor.But this only if you adjust for the bezel separations!Is a triple wide view worthwhile? Try driving a car with NO windows and only a single cam/monitor ahead of the driver.The argument is sometimes made that panning eliminates the need for a WIDE view- but panning also means that instrument gauges and switches are constantly displayed in different locations on the screen. (And then may have to be zoomed to be readable.) I believe that is the reason the FAA will not permit panning in an approved Flight Training Device.Alex Reid

Do you mean it is hard to set up det wide view or is it easy (Plug and play)And why will the 2/3 of the monitors be frozen i have seen many simulators with more monitors and i will have 3 monitors for window and 1 for panel

This is not correct: With TH2Go your video card drives a single display window of size 3x the horizontal screen resolution of the individual screens in your setup. Because the pixel count is now 3x the pixel count of a single screen, the GPU will have to work *about* 3x harder.Cheers,- jahman.

i'am talking about the HD5780 not the TH2GO Is it easy (Plug and play) or hard to set up a Wide viewand why will 2/3 of the monitors be frozeni will have 3 monitors for window and 1 for 2D panel

I don't know what that test is, but I actually had a 5870 2gb, the card is simply not good for FSX, ATI cards do their AA some way that makes them croak in heavy cloud burdens, and you can't run them at the higher levels of AA. Supersampling AA will kill performance.The multiGPU soluction in this case is to enable widescreen gaming, I have two GTX 580s and they run FSX at the highest settigs just fine, my old 5870 couldn't do that.

patrickbc- I have not used either HD5780 nor TH2GO, so can't advise on them.I have two video cards producing 3 separate views- Left Forward, Forward, Right Forward.Each of these views must first be computed by the Central Processing Unit (CPU), then forwarded to the proper video card to be organized/formatted for its own monitor.The CPU can recompute only one view at a time so the other two views are stationary at that instant.As long as all three views are updated rapidly- one after the other, you see the whole thing as being very smooth.Smoothness depends particularly on the 3 views being integrated into your specific monitors by adjusting the angle of the outer views so that they are shifted sideways by the width of the monitor bezels. That is to say that there is always a wedge of scenery you cannot see because it is hidden by the bezels. Just as in a car there is always a wedge of scenery you don't see- hidden behind the windshield pillar.One thing to be aware of is that there is a natural optical problem in projecting the world on flat monitors. In real life we actually see the world around us as if it was projected on the inside of a giant sphere. That is why we can see a cloud or airplane directly overhead. It is essentially the same problem that map makers face when drawing global/spheroid maps on a flat surface.With multiple monitors you can correct horizontally by arranging the monitors in an arc so that each is approx square to our eyes and this will keep the horizon as a straight line when the airplane rolls- even thru' a 360º roll. (Aerobatics are great fun- but keep a barf bag handy if you suffer from vertigo.)But in pitch up/down, because there is only a single flat surface vertically, the horizon will bend between the monitors. I minimize this by keeping the 2D panel on the bottom half of the 3 monitors- so the scenery or view occupies only the top halves of each mon. (Much like a real cockpit where the view occupies the top half and the panel fills the lower half of the whole image seen by the pilot.) This way if you pitch down, the scenery tends to disappear off the monitor top. Or in pitch up, the scenery disappears behind the panel. Either way the bending of the horizon between monitors is barely noticeable. If you use the monitor(s) for scenery only be prepared for this horizon bending- which can also be eliminated if you wish to raise and lower your chair or bob your head every time you pitch up/down!Alex Reid

So you will rexommand a multi GPU solution with the GTX470 x2. Shall i have a special program to run on 4 monitors with 2 GPU's .Can you send a picture or a video (PLEASE!!!) showing the horisont when pitching up and down in 2D cockpit without the panel (Because the panel shall be on monitor number 4, and monitors 1-3 will only show the window)Thank you

This is my wish....But only 1 monitor to the panelWhy is that so hard!!??

Okay i have run a demo on 1 monitor and i can see the problem with the horisont but how do i get it like him

That is cool...But how... I know he useing projectors but monitors and projectors is the same right (with this problem i mean)
