Frame lock

[robert41]

Had an interesting find the other day.
Usually I keep the frames locked at 60. This gives me a very good, clear, smooth graphics except for AI being jerky when flying with them.
So I decided to lock the frames at 30 for a flight. This made the AI nice and smooth, with a slightly less clear graphics. A little grainy.
But then I noticed the pan rate was speeded up as well as the rate when moving the view point, up/down-left/right, was much faster. And very jerky. Also, my trim adjustments, using buttons on my flight stick for the trims, slowed way down to a crawl.
Has anyone seen this before?

Not really Robert. I fly "unlimited" so I rarely see much stuttering and I know you can set the "pan_rate" in the FSX config file so I'm not sure how the adjustment you made for framerates affected something preset in the config file. Interested to see if anyone else has experienced this though.

Like Ed I run unlimited. See what that does for you.

I did try with the frames unlimited. Similar pan rates/trim speeds and jerky AI as having them set at 60 except with aircraft that have shaking, vibrating panels, like A2A's B17, these go from shaking to a wavy look. Like being under water.
This was also with some time spent adjusting/playing with NVidia graphics settings at different frame rates.
I am also at a loss as to why the different pan and trim speeds.
Running a 4790k, NVidia 970.

What's your pan rate set to in the FSX.cfg file?

[robert41]

Could not find any pan rate in the CFG.

Could not find any pan rate in the CFG.

Sorry Robert, that was FS9, in FSX the pan rates are part of the Cameras.cfg file in the same folder as the FSX.cfg file. . .designated as PitchPanRate= and HeadingPanRate=

[robert41]

Ok.
Pitch is 30
Heading is 75

Does that mean that with unlimited we' ll have less stutters?

[Dangerousdave26]

Video settings and frame rates are system dependent. What works well for one system might not work well for another.

I have TrackIR which is independent of those settings but you can increase them (if they function the same as FS9) up to 99. It may take a bit of testing but try increasing those numbers and see if that doesn't help.

+1 Thank you for stating the obvious. I have tried unlimited and it was a joke. What works for one simmer and how they want the sim to work will not necessarily work for another.

I have tried, with my antiquated computer, unlimited, 60, 30, 24, and 20 fps limited. What works well in one scenario does not work well in another. Generally speaking, limiting frames seems to work better in situations where the computer/video card is struggling to keep up. Slow loading textures and blurry textures will decrease with limited frames, but often there will be stuttering with AI, panning, and taxiing. It's a trade off.

Sorry to mislead about this. I am not trying to change the pan rates, just interested in why they change when setting different frame locks.
