3 views with SLI

[James Twomey]

Okay now I'm confused. I thought that purpose of having a SLI capable mother board, with a second video card was to enhance video performance?

I have a quad core mother board with dual video card capabilities and was thinking about putting a second one in. Are you guys suggesting that i should just leave my one video card in for better performance?

For FSX and Win XP (any version) SLI and Crossfire do not work. If you have Vista and DX10 with the patches, SLI and Crossfire will work but not with FSX. FSX and FS9 were not coded to take advantage of this.

Thanks! Well aint that a bummer then!!!

With which configuration we can get more frames?

1st) With one big VGA card (give us 2 views) and with a another small VGA (one more view)?

or

2nd) from only one big VGA card and connect the TripleH2G.?

Any test in these 2 configurations? Which have more frames? or not exist any difference?

I believe that you should also be aware that the Jury is still out on DX10 if you research the Technical Blogs in areas other than FSX but certainly it will of course come good in the fullness of time.

There are two matters that should be considered when upgrading video cards:

(1) In quite a few motherboards you will find that if you insert two (dual) similiar graphics cards in the dual PCIe slots the speed of the Primary PCIe X 16 (PCIEX16_1) slot changes to X 8 mode after you install any device in the Secondary PCIe X 16 (PCIEX16_2) slot.

(2) SLI is not currently supported in FSX.

I have found that the one Graphics Card (Gainward 7950 512MB 1200 X 3800)
at 16X Speed with TripleHead2Go can fully excercise a Q6600 or a Q6700 Quad Core based system. I have tuned for excellent frame rates of 40 to 50FPS.

I would not worry too much about SLI but would concentrate more on "load balancing" in your "quad core" system!
If you do it right you will be more than satisfied!

Bill,

Thank you! But I do have another question about the Load Sharing that you were discussing. Do you mean load balancing by evenly assigning the work across the 4 CPU's?

I have a question about DX10. How in the world can we compare DX9 vs DX10 screen shots unless we also have DX10 hardware on our own computers. Make sense?? If i have an old AGP card and winxp w/DX9, i sure am not going to see DX10 stuff in all it's glory. Or am i missing something obvious???

You MUST have Vista to use DX10.
FSX does not use DX10 to its fullest extent.
You will see some differences but overall, I'd wait for FS-11 for DX10 and full use of multi-core.

Thats my point, how can you look at someone else's screenshots showing DX10 if you yourself don't have Vista and DX10 on the computer you are using. I see it on all the forums saying they see no difference, DUHH!! How could they w/o the same new hardware and software.

[AndyT]

I know what you mean and frankly, there is no real way to compare them. However, DX10 does look better. I've seen some pix of it and it has more of the smaller details that give realism. Just need to get a nice new machine that will run it.
