I think the bufferpool is actually system memory. The bufferpool size is how much system memory will be used for video in FSX before the CPU offloads video processing to the GPU, hence the "CPU" bound concept of FSX. This would also explain the performance of turning off the bufferpool, which allows the CPU to send video processing straight to the GPU. The RAM on the GPU becomes important not because of the bufferpool size, but because a fast processor (i7 4.0Ghz+) will send commands very quickly to the GPU, so a fast GPU with large amounts of RAM will better be able to handle the incoming requests from the CPU.

Very good point/explanation! :(

Thanks, but don't take it for absolute truth. Hopefully someone with more knowledge than me can correct me if needed.

I think the main thing to remember is every system is different and FS responds to your individual system specs uniquely. There is no real perfect setup/cfg file. Plus you throw in a persons individual tastes as to what they want out of FS, eg visuals, flight dynamics, AI traffice etc etc and everything comes down to trial and error to get it how YOU want it.All these posts and tweaks are guides only to what is 'generally' considered to be helpful :)

No idea about FS9, actually. I read about this in the Orbx forum (can't find the post now, though). Luckily I hadn't made the switch to 9.11 yet, out of a combination of laziness and having been burned by updating drivers in the past. Since they were working fairly well, I saw no reason to use the newer ones, and I guess that was the right choice!

Hadn't heard this before. Is this true of FS9 as well?
