ADITIONALLY : the cpu and gpu shows not even working at 50%...... why PP3D can´t use all the system potentiall??

There are many factors to consider. First off, 1GB of graphics memory is a bit low for high resolution multi-monitor usage because the way the API works, each monitor needs its own copy of textures and vertex buffers.

The app is CPU bound because it's still running DirectX9 which requires all api calls be made on the primary thread. Thus all your core rendering tasks are on your primary cpu. Background tasks like terrain / scenery generation and streaming are threaded out but those aren't going to totally peg out all your cores.

2nd, you should probably try setting up Eyefinity. Here is a setup guide i found with a quick search.

That way Prepar3D only has to draw the scene once, and you let the ATI driver do the heavy lifting for you. You'll need to experiment with various group configurations to find the one that works best.

Finally, what kind of display settings are you running, and what kind of data are you displaying on your screens? You will likely need to crank your display settings down some and consider using some screens only for 2d panel displays.

Hope that helps

thank you bhollis , so the idea is to have just one monitor for 3d rendering, that was the idea from the beginning, but here in colombia was dificult to find a display port adapter, so the other choice was matrox 3h2go but hard to find to, so 3 gpus was the final choice, so i can't use eyefinity whitout a display port converter.... bad luck, you think it will be better if i have jus one monitor whit 3d? i have the default desktop whit the main window off prepar3d, 2 more for a front view, and 3 for G1000 and instruments........

atorque thankyou for the answer, but why you sai intel and ati/AMD dont work together? really makes no sense say that, intel and NVIDIA are great but not mean to be together necesarilly. besides intel have more power than AMD and ATI/AMD performe better than NVIDIA on big resolutions whit filters. yes i have the money for an i7 but not for 3 6950..... sorry about that........

ok, thank you for your opinion, but have 2 say is not a fact waht you say that demostrate nvidia was thinked for intel..... in fact, nvidia and intel don't have a good relation ship, since intel regreat on give the x86 to nvidia..... thats why nvidia cant make x86 processors........ AMD/ATI thats true, meant to be together, but not necesarilly that way. i think you gave me a ATI/AMD fanboy answer.... but thats ok.
