You definitely got better than 30fps in FSX? Possibly the PC is just a bit underpowered, but I would have thought just about OK in P3D.

In FSX, I was getting a maximum of 30 FPS. I usually got 20 to 25. I didn't pay a ton for the PC, so it may just be that the PC is under powered.

Thanks a lot for your help.

Thank you too, because it's been interesting. The problem with the halving fps with the undocked window may well then be a situation arising with the NVidia drivers, so I'm glad you tried that test.

 

Probably need to get a proper PC rather than try to upgrade that one. They come on a lot recently. You read a lot about new CPUs but they still perform in little increments. Big increases come in PC speed with latest motherboards, memory, SSDs, and GPUs.

Did you try disabling tessellation?

I tried that and it had almost no affect.

What graphics card do you have?

I forget exactly which one I have, but is has about 1gb DDR3 of vram. I am planing to build a new computer in the near future, as this computer is not great quality (and a few years old), so it isn't worth upgrading.

I would venture to guess that your video card is not up to the task. In doing a quick online search of GPU's that have 1gb or ddr3, that is in the realm of a gt720, gt601, or an ati5450. As P3D uses the GPU much more than FSX, I can see the scenario of much better frame rates in FSX than in P3D. Glad to hear that you will be upgrading your system and I am sure you will really enjoy P3D.
