Is there any advantage overall in limiting FSX frame rates to say 30 frames per sec as opposed to setting them to unlimited.
I have a fairly high end gaming computer and I see really little difference either way.
Thanks

I set mine at 30 FPS because my machine is ancient. It can't render images at low and slow over cities much faster than that. But the human eye can only use about 28 frames per second, give or take a few frames. So If your machine can render faster, you might be picking up more details and that is good. I read an article once that dogs are believed to see at a very much higher frame rate than humans, which seems to explain why they can focus on a frisbee while at a full speed run and jump to catch it.

I also set my frame rates to 25-30 FPS for two reasons, anything faster is probably just a waste or computer resources, and 25 FPS is the recommended speed for Multiplayer, so as not to overload the Multiplayer Server.

And your reference to Dogs "frame-rate" is very interesting, Steve....
I have often wondered the same thing regarding small birds, like the garden Sparrows in my garden....

...how they can accelerate at very high speed towards a tiny twig on a tree, locate its distance very precisely (even with its eyes on either side of its head!), decelerate very rapidly, land on it, collapse its wings and curl its toes firmly around the twig with great accuracy, all with perfect balance.....!
That has got to be very powerful eyesight and brain power!

Likely the same reason cats can roll over and land on thier feet during a three story fall. Maybe?

I regularly practice that procedure, Steve.... ...

If you set a limit to the framerate, and your machine can exceed it, then your machine can very well spend some time doing other things like rendering detail, moving air traffic around, whatever else you can throw at it.

I set mine at 30, and at altitude, only the CS 777 gives me a hard time. But, now I can run other things like Ultimate Traffic 2 (highly recommended) and UTX. While it was able to crank out 30+, now instead of just drawing new frames, it can fetch and display textures in it's downtime between frames.

me....limitless in fsx and 30fps limit in nvidiainspector.....

I have no problems at unlimited, but i do get problems in scenery updates when i run 30-40 limited
