[quote]Can we assume that the PCI-E x8 lane can actually reach its theoretical maximum bandwidth?I think the bandwidth of the PCI-E is the smallest of problems here. With resolutions as high as 3x 2560x1600 (7680x1600) the power of the computer will become a problem a lot sooner, considering that you can't even use SLI. Not to mention that there aren't many people that even have 3x 30" monitors :P PS. I did some recalculating, the actual bandwidth needed for 2560x1600@60Hz should only be about 1GB/s. That what I heard of was that the f. g. the performance with 2 8800gtx at GTR2 at 3 x 1600x1200 was worse than 3840x1024 with one 8800gtx card and TH2go. Is it true, if yes what is the reason when it is not the pcie interface ? |

SoftTH doesn't support SLI, so the in both cases the game is rendered using one 8800gtx. What you are comparing is a game running at 4800x1200 vs 3840x1024, the latter is a smaller resolution so it runs better because of that. |

I'm wondering if the PCI-E bus would ever become a limiting factor.I don't know how fast the PCI-E bus is in practice or if there is some overhead that is needed besides the image. But I am quite confident that the PCI-E bus won't be a limiting factor in any case. |

You mean the second 8800gtx is not rendering though she is connected to one 1600x1200 screen? SO it does not matter what the second vga can perform? |

Correct. The second GPU during SoftTH use simply receives a fraction of the image and disaplys it on the connected monitor. The primary GPU does 100% of the rendering.SoftTH doesn't support SLI, so the in both cases the game is rendered using one 8800gtx. What you are comparing is a game running at 4800x1200 vs 3840x1024, the latter is a smaller resolution so it runs better because of that. |
