Thanks--I guess I'm just dumb lucky as I didn't notice any tear lines w/o a specified parameter.

I never really noticed any either. I think it's more evident in other "games" where you have high FPS and dynamics.  In any event, I a 3840 x 2160 res monitor has 2160 vertical scanlines per frame but some number of those (I can't remember how many) are actually off screen, a kind of buffer. So if you set -1 you are telling RTSS to put the tearline 1 line below the last displayed line, so off screen. you can make that -1 or -2 or any negative number less than the number of lines off screen. Setting it too negative will just wrap the tearline back up to the top and down a number of lines. BTW, this is much more than I really know about the subject 🙂

For those of you who do use unlimited FPS in the sim, how have you resolved autogen popping?  Or simply something you've "lived with?"

Ive never used a FPS limiter. I get around a fluctuating 30-60FPS at all times, soon as I limit they drop to around 15/16? Am I doing something wrong?

No one uses the internal limiter in P3D anymore unless they have been living under a rock as it typically causes more harm than good and that has been for a very long time.  If you have stutter-free, fluid video then you're not doing anything 'wrong'.

If all else is the same, why is autogen popping better with limiting in sim vs externally? I always thought that was more a function of other parameters.

Beats me.  Giving RTSS a whirl again since multiple people seem to swear by it recently: I observed that limiting via RTSS but setting unlimited in the sim created large swaths of missing autogen until either I paused, locked frames in the sim again, or slowed down significantly.  Was also able to repeat it between sim sessions.  Tried locking RTSS at 30, 36, 40, and 48 with similar results with Vsync in sim both on and off (144 Hz panel with Gsync enabled, flying in windowed mode).

Since there's a lot of opinions on here, and I'm still trying to hone in settings based on recommendations in this thread, that would be applicable to my set up....has anyone gotten "smooth" performance with the following (my FPS seem fine and stable):

 

-High-refresh panel (120 Hz+)

-Windowed mode

-Nvidia GPU

-P3D v4

 

Thanks.

Limit frames with vsync, that's how.  I have no autogen popping, and I run unlimited.

I run Unlimited but with vsync on, and vsync on is a de-facto framerate limiter.  Autogen popping can occur when main thread usage hits 100%, and even before that if thread saturation reaches a high level.   Since I run 30hz (or 50hz or 60hz) refresh with vsync on, I rarely have my main thread hit 100% usage, thus no autogen pop issues.

The only caveat to this is if I fly 600+ knots at low level.  That's a whole different ballgame.

If you read up on the FFTF setting in the sim, you'll see that the unlimited fps setting can starve the sim of texture loading time.. if you get "blurries" or missing autogen, first thing to try is to increase the FFTF setting.  The default when limiting within the sim is 0.33.. which you can try as a test.. but I find that 0.15 does the job for me..  (or look into the FFTF Dynamic app..)

Try this:

[MAIN]
FIBER_FRAME_TIME_FRACTION=0.15

Based on the survey results in this thread, about a third of our members have been "living under a rock".. there appear to be three popular ways of limiting fps.. 😉
