Matrox Triplehead2Go and texture tearing

[Shawn]

I recently installed a Matrox Triplehead2Go and three 19" monitors for my forward visuals, I also have a 4th monitor displaying the 90 degree right view and two more monitors displaying guages. After installing the Triplehead I have noticed that terrain textures are now loading much slower/popping. With the fps set to unlimited I am staying steady at over 100 fps so it doesn't seem to be an issue of things just running slowly (this also happens when I have only the monitor attached to the Triplehead running). Has anyone else experienced this slow down of texture loading? I quite familiar with tweaking Fs9 and have all the usual tweaks installed on this computer. I am also experiencing some texture tearing when I am turning close to buildings or very close to terrain. When I enable VerticalSinc my right hand view (which shows the engine nacelle and wing tip) gets distorted, I think I can fix that though by using a 2D cockpit view instead of the 3D.

A TH2Go WILL slow down your sim. Its making it create a screen 3 times what it was. That takes more compute power and so I advise reducing your frames and locking them at 25. Your eye will never know the difference and that will give the machine time to catch up and get everything drawn faster.

Thanks Andy, I tried locking my frames at 20 to see if it would help but all it did was give me the sutters Normally I have my frames locked at 55. Personally, I can see a difference when my frames are locked at 25. It's a bit of a myth that the eye can't recognize frame rates faster than 25, this only applies to images that have been blurred to trick the eye, like what's done in motion pictures. Flight simulator displays each individual frame without any motion blur which is why screenshots turn out so crisp. This explains it better than I can...http://en.wikipedia.org/wiki/Motion_blur

Then try locking them at 30 or 35. The fewer screens you need the faster they draw.

I didnt have the same experience as Andy as I have the TripleHead2Go and it didnt slow mine down a bit. The TH2Go does take more to draw everything but it has its own GPU and resources to bring to bear to make up for it. My experience was that adding the other monitors on my extra DVI outputs of the graphics cards are what slows everything down. I think you would find that the performance would be similiar if you remove the TH2Go and just connect one of your 19" monitors. But take some monitors off the Graphics cards and you will see improvement. I tried using an 8800gt and a 7900gt in the same box and then attaching monitors to each of the 4 outputs. After I added the 3rd monitor things when south. I ended up sticking with just the 8800gt then hookiing TH2GO on one output with 3 22" monitors and put a 17" monitor oon the other 8800gt output. Performance is great.

Where did you get that information? I never heard that. Does it apply to the analog version as well? Do you have the digital version?

Thanks again for the replies gentlemen, I managed to fix my issue by enabling VSinc and setting my fps to 60 which is the max refresh rate of my monitors while using the triplehead. My textures still aren't loading as fast as I like but I'll keep adjusting my settings and I'm sure it will get worked out. I have to say the triplehead is a great bit of kit and having the 4th outside view is really nice.

I am sure I read that it does somewhere but cant remember where. I have the digitial version.

As far as I know it does not have its own GPU. I sure wish it did!

I will have to find it. It has some type of processor for sure. It is not a $300 fancy Y connector. It has to have processing power.

I will locate
