Chasing Stuttering Red Herrings...and then Eureka!

[PurdueKev 159]

ARE YOU FREAKING KIDDING ME!?!

I have been chasing those particular word not allowed stutters since v4.0... and this was the issue the whole time???  I just did a few test flights with that on and off, and I'll be damned if I can now induce those "surge stutters" (to coin a phrase) at will, at least in the few scenarios I tested.  Anchorage in Orbx Southern Alaska, for example, is a particularly nasty scenario with the wrong settings (three big airports, water, lots of autogen and dozens of airfields all over the place), and this made flying there a much less frustrating experience.

I need to do some more testing, but it is definitely not a placebo since those "hiccups" that you describe are really easy to see.

I think this is a Windows problem not a P3D problem. I've seen it in beta testing. Has to do with a update to Windows10..

Try this: Right click p3d icon, go to properties, check the box for "disable full screen optimisations"

See if it gives the same effect as unchecking that box in P3D.

Slayer, I have had "disable full screen optimizations" checked on all of my shortcuts for a while now, and even toggled the documented registry edits to make sure Game Mode was not running. None of that was doing me any good until messing with the Auto-Fill setting. I don't know if there was something in my Windows setup that was preventing that from working for P3D, but I can verify on my system this seems to make a big difference. I'm scratching my head as to why, but I won't look a gift horse in the mouth.

This might make the wait for v5 to be fixed a little more tolerable. 🙂

Addendum:  might as well ask--any way to get the screen to fill all the way out w/o checking the box?  I know there is no native full screen mode.  

In prepar3d.cfg, I tried changing LocationFullScreen=x1,x2,x3,x4. I changed x3 and x4 to the resolution of my monitor and kept x1 and x2 at 0. For example, I have a 1920x1080 monitor, so I changed that line to ...

LocationFullScreen=0,0,1920,1080

It didn't work. Each time I tried, it changed back to LocationFullScreen=0,0,1912,1072. Can't figure why.

Because you loose pixels for the window border width? 4 pixels each side.

Thanks, Steve. That's got to be the reason. Too bad. As a workaround, I've changed my wallpaper to a black background.

Same. I have stutter-free performance whether "Auto-Fill Main View" is checked, or unchecked. Using Nvidia driver fps limit at 30 on a 2560X1440 Gsync monitor.

Limiting fps that low won't work for me and disables Gsync anyway. I am running my monitor at 50Hz for P3D with Gsync enabled - my monitor is not capable of 30 Hz. If you aren't seeing these stutters in your setup in the first place, this won't have any effect.

I found a nifty little app called Borderless Gaming for just this purpose.  Does exactly what P3D's auto-fill does but the stuttering issue described above remains gone .  Oh man I am stoked!

Also, I'm testing this now what LM Beau Hollis suggested disabling full screen optimizations and disabling game bar as well so I am testing for that right now.  If those two actions don't help there is fortunately Borderless Gaming.

An interesting thread, Noel. I have had "Auto Fill Main View" enabled for as long as I can remember, so I am going to test this theory with the option disabled during my next series of flights. I will let you know if it makes a difference.

It's just a placebo for the OP. All that function does is adjust the size of the application window to the screen. Nothing more. Why would it have any effect on stutters? It does one thing (fill the screen) and nothing else until you tell it to.

Every other day on this forum it's someone bursting through the door to tell us about their latest revelation. 🙄

Stutters is placebo now, gotcha.

Solutions to problems are not always the logical ones. I will reserve judgement until I have tested it.

Sorry you had trouble interpreting my post. I'll try to make it easier to read next time.

Sorry you can't make a post without being condescending and adding roll eyes.
