Hey Fellas,I'm presently running 3 - 23" wide screen Acers (1920 X 1080) with 1 GTX 580 and a GTX 240. I like to fly GA, VFR over the PNW area. I do not have TH2Go and so I am having to live with 3 undocked windows in VC mode. I would love to hear your opinions about whether or not it would be better to invest in TH2Go or to purchase a second GTX 580. If I went with a second 580, I am guessing it would be good to tie them together and maybe try something like Nvidia's Surround?I'm hoping that I might hear from both sides here as I am really not at all sure which way to go. I am tired of living with the large price I am paying (FPS loss due to 3 undocked windows). Thanks very much for checking this out and taking the time to send your thoughts on!John

What's best for you depends on whether you are using head-tracking software or not.If you are, you need a single VC window for proper panning and this means the TH2Go (Or an AMD card with Eyefinity).If you're not, you can go with a second GTX, but you should know every video card consumes scarce address space available in FSX for the RAM window needed to send data to the video card (and I have never been able to find out the size of that window.)Cheers,- jahman.

Thanks Jahman,Funny you should point that out. I am also thinking of purchasing TrackIR 5. I did not realize that I might have problems with proper panning. Presently I am able to undock 3 windows, align them, press the "X" key and get them all to pan in a coordinated fashion using the hat switch on my CHH yoke. I presumed I could do about the same thing when and if I installed the TrackIR 5 system. I guess I was wrong.John

Jahman - another question -I am confused regarding just how TH2Go works with FSX. I believe it actually "splits" the window into as many as 3 separate windows but does that mean you will realize the FPS rates that you would ordinarily receive with just one window open? For instance, when I use just a single view open my FPS rates hover around 40 - 90+ depending upon whether or not I am flying over populated areas. If I open 3 undocked windows that FPS rate drops significantly down to as low as 11 - 15 FPS over populated areas. If I install TH2Go I am assuming I would see an improvement in FPS and I guess it would be somewhere in between the rates I get with just one view and the much lower FPS numbers I live with when I have all 3 views open but I am really interested in what others have found.Thanks!John

John, the TH2Go combines the 3 monitors into a single screen so the video card things there is only a single huge monitor.Your FPS will depend on the pixel count of each monitor,on the speed of your video card and on the type of anti-aliasing you select.Your FPS will be the lower of FSX FPS and your video card FPS so, for example, you can increase your video AA "for free" without reducing your actual FPS as long as your video card can deliver an FPS that is greater than the FPS your CPU can deliver.Cheers,- jahman.

jahman - thanks again my friend for the information. It sounds like it would be better for me to consider TH2Go rather than the extra GTX 580. I am very unsophisticated and largely ignorant when it comes to things like pixel counts, anti-aliasing and video card speeds. You know - just a thought now - but it would be wonderful, especially for someone like me if there existed a tutorial series that would help the FSX user who is relatively unsophisticated in the workings of CPU's, video cards and the like understand the importance of these things and just how they work together to produce the environment that we see on our monitors. I confess that I have little or no idea of the implications of adjusting many of the FSX settings and so it really boils down to a "hit and miss", "trial and error" situation for me. I suspect most of us would be more than willing to commit to the time necessary to "get up to speed" so to speak however many of us, including me, do need to be pointed in the right direction at least initially.Thanks for sharing!John

You bet, glad to be of assistance!Pixel count is just the number of pixels tall and wide of your monitor times the number of monitors. The antia-aliasing is the calculations the GPU on your video card performs to smooth-out the jaggies and show you a crisp image with lots of detail.The best technique to get up to speed on the particulars of hardware and software re: FSX is to sign-up to be notiied of updates to the forums/threads of your interest as there are many folks in the know sharing their expertise with the rest of us mere mortals!Cheers,- jahman.

TrackIR works fine with TH2Go over three screens, I can recommend it. Also enables you a fourth, touch sensitive, monitor if you like. Drag 2D panels and CDU onto it for "real" manual button push.TH2Go limts the resolution to a max of 5040x1050, but that's enough for me .Bjorn

Keep in mind that for a TH2GO configuration with 3 x 1920 x 1080 monitors, you will have to use the DisplayPort version of the TH2GO, which entails either having DP-capable monitors (not universally available, especially on smaller or older displays) or a ~$100 DP-to-DVI converter for each of the monitors. Also, at that resolution, the monitors must be capable of synching to a 50Hz signal (again, not a universal capability for monitors, at least in the US)

Looks like Eyefinity is the way to go then, TH2Go is troublesome and expensive IMO, can buy a good AMD Radeon card for the price...

I checked the specs on my Acer G235H monitors and the horizontal synch range is 54.2 - 83.8 Khz - vertical synch range is 49 - 75 hz. I believe they are DisplayPort monitors as they plug directly into the GTX 580 without requiring the adapters. Do you think they will work with the digital TH2Go?John

I'd just like to add to this,I run TH2GO with GTX570 and Win 7 64bit. I am running it at 5760x1080 res. ( with DVI input ) with 3 samsung syncmaster 2243 monitors, they are fairly expensive.With the latest Matrox GMX files, I was only given 2 refresh rate options, 57hz and 60(input 59)hz. Even though Matrox say you need 50 hz I have set it to the 60(input59)hz and it runs great. very little impact on performance,Even if your monitors won't support this, it looks much the same as with the lower res of 5040x1020. again, Matrox say you need 57hz, but it runs with 60(input 59)hz.I have never tried 'eyefinity' so I can't comment here, but TH2GO will give better performance than 3 undocked views. TH2GO is very simple to set up with WIN 7, ( if done correctly ) and I've never had any problems with it.If you decide to go the TH2GO way, let me know and I can give you a setup guide to do it successfully on Win 7., there are some issues that were notapparent in XP.best regards,Ron.

@ronski: Does Eyefinity have "undocked views" - and what is that?Oh it´s confusing, and difficult what to choose...I have a GTX 460 1 GB, would that be enough for TH2GO?BTW: CPU i7 2600K 4.8 Ghz, and 4 Gb Ram..

FSX has undocked views. Bring up task bar/views and select a new view of your choise. Right click to undock and drag onto a separate screen. No need to undock on TH2Go, you just drag the window across the three screens. I undock to get 2D panels on my touch screen.I ran TH2Go on my GTX 285 1GB, all depends on how far right you set your sliders.Bjorn

I'm not sure what you're trying to say with this. Of course you can have a single VC window with dual Nvidia cards in surround mode.Head-tracking software works equally well with th2go, eyefinity and surround mode (I have tried all of them).
