If you're getting 40 in the 767 and Zibo, with the hardware you have, I'd imagine you're running your graphics settings quite conservatively. I'm hoping others with systems close to yours could chime in, but in my opinion, based on what you're getting with the aforementioned aircraft, I'd say the TBM will hit high 20's to mid 30's in fps. But that's just an opinion, and should not be taken as official.
