Where this usepools=0 config can be made? On the fsx.cfg?

Here is the results thread. There are a few others on the topic as well as to how to produce more stable results.http://forum.avsim.net/tutorials/article/64-the-bp0-conclusions/

To reiterate Markus' question...Has anyone seen benefit in FSX running SLI/Crossfire with usepools=0 (or bufferpools=0)?

******* has twin GTX480s and did say that it gave him an improvement - I'd ask him directly to be certain though.

Only so far as the game is hugely CPU limited - most games don't have any sort of dedicated SLI mode, it's just that they utilize the GPU a lot more and the driver knows how to split that across two GPUs. SLI isn't like multithreading (which is what multicore CPU use is) - the two GPUs actually combine to draw different parts of the 3D scene independently, that's where the boost comes from, each card is doing half the work.That's actually probably ATI's doing - Nvidia and ATI create SLI or Crossfire profiles for games that tells the driver how to split the load between them - they probably just never bothered to make an FSX profile because the GPU utilization is so low to begin with.

Thanks for the explanations, now it's crystal clear !

And what resolution were you flying at? Did you use high AA settings? And did you use usepools=0? Please be a bit more specific before you say that it's completely useless...Markus

I did not use that tweak,I can't remember but I think 1280x1024x32bit,and my AA settings are always high at 8x.Mine was a crossfire configuration.It would perform exactly the same with one video card,no difference.David Di Domizio

I think I saw some improvement in using usepools=0. But my PC is so old that it didn´t make much difference. I´m using a Athlon FX-60 with SLI 9600GT, so the graffics weren´t overwhelmed by using this tweak. And thanks for the help, Jeff.
