I read somewhere that FS10 does not support SLI at this point, and won't until VISTA. Will this make a difference with this sim? Clearly mutliple cores are not the answer because the developer has admitted that the sim is not really optimized for multiple cores.I wonder if this is a hardware advance that the developers were counting on for decent performance. Curious to hear from folks who understand this better than I do. I'm not optimistic because it seems like we are still CPU limited. Colin Ware in Portland

SLI is rather simple really... you will notice it's performance advantage if running high resolutions (1920 x 1600 or higher for example). At lower resolutions SLI is wasted money with FS at this point in time. That may/may not change when Vista/DX10 is released (depends upon what rumor you wish to believe at this point in time).I recall seeing a poll at Driverheaven a few weeks ago that showed that only 0.5% of the respondents were using SLI or Crossfire.Cheers,Greg

I'm currently using a SLI configuration with a pair of 7800GTs. Running at 1920x1200 which is the native resolution for my monitor, SLI makes no difference whatsoever (quite literally the only game I have where there is no difference) unless I assign it to antialiasing.For the record, I'm finally in a position where FSX is running well enough. The biggies for me were water being lowered to 2.x low and, yes, no autogen. And that's inspite of the tweaks people have come up with.Mind you, as soon as the new England and Wales photoscenery is released in the next couple of weeks the autogen won't matter to me anyway :DPersonally speaking, FSX is light years ahead of every other version of FS I've used (starting with 5.1). Sure, I'd love to run with full detail but right now I can't. Big deal. I couldn't run Mafia on full detail when I first bought that. Or Oblivion.
