WHOA! So That's How You Do It!

Recommended Posts

After all these years in P3D... and struggling to get good FPS with the PMDG... I finally figured it out on my system....

 

1280 x 720.      I stream on Twitch/YouTube, which I can only stream at 720p.   So it got me thinking.. why don't i just put the sim in 720p also?   So I did that today, flying in windowed mode which still makes the view screen 1080p and I set my in-game resolution to 1280 x 720.   I just backed out of a payware airport with 45 FPS in the VC instead of 25 and had 60 FPS on the ground and in the air.    LOL...  and the great thing is... there is so very little difference in quality between 1080 vs 720 that I miss nothing about 1080 .... I am kicking myself for not trying this sooner.   I am in flight sim Heaven now!

I bought a 4K monitor knowing full well that my eyes are no where close to that so I may give it a try.

Are you sure what you have done has made a difference? I don't have P3D but in FSX what you are calling 'in-game resolution' is actually 'full-screen resolution' and has no meaning when flying in windowed mode.

I tried it with my 4K screen, set to 4K in Windows, but set to 1080 in P3D and saw no difference in frame rates

compared to 4K in Windows and P3D.   :(

Its a well known fact running in windowed mode gives you better FPS.   I run every game in windowed mode.  But then i again i also do this so i can use other features like pull up charts, weather, etc.

1089p gives me way more frames than DSR at 4K. Windowed mode is also way better than full screen

It's probably all just placebo.  I've always run in windows mode.   I don't know if this did it or something else changed but I am getting these frames now, regardless of what I did.    I usually run in Locked FPS mode through Nvidia Inspector @ 30 FPS.     I turned it off so I could see my maximum FPS and see if changing screen resolution would have any impact and I was seeing 45-50 in the VC and 60 outside the plane.   I did not use to get that with unlimited FPS and no locked.   It was more along the lines of 25-30 at payware and about 45 outside.    I have been in locked FPS mode for a long time so it could be that I changed something else and just THINK it's a screen res thing.   As stated, I really don't think this resolution setting has any effect when you are in windowed mode.   You have to phsycially change the size of your window to get a resolution change I believe.    I didn't get to do a flight yet fully unlocked (which is not recommended by a lot of people) to see how smooth the sim is.   I did takeoff from FSDT's KLAX and from Drew's KLGA, two areas that usually have terrible performance.    I had 40 FPS in the VC and KLAX and 30 at KLGA.     I usually have 25 at KLAX and 15-18 at KLGA so SOMETHING changed for the better on my end.    My in-game settings did not change.


What graphics card do you have ?

 

It's a GTX 980.

And yet, there is a full-screen mode  :mellow:

Huh? Of course it does... not sure what you're calling "full screen resolution" but he's not doing that.. he's just stretching the window to fill the screen (or rather the monitor is scaling it) but the program (sim) is rendering at 720p, and it DEFINITELY has an effect of being faster...

Well, one of us is confused  :blink:

P3D has no full-screen mode.  Even if it's filling the whole screen, it's just a borderless window sized to take up the whole screen.

 

I guess it all makes sense.... Shrink the window and there's less pixels to push = better performance.  Reduce the resolution and the number of individual pixels are "virtually" reduced = better performance.

 

Reduce resolution and shrink window size below that resolution... fasten your seat-belts!

Well, it's not me... if you set the in game resolution to 720p, that's what it renders at, period. Nothing to be confused about on that...

What? It doesn't matter if you "shrink the window", the game still renders/processes at whatever resolution you set it to... all you're accomplishing is losing detail at no performance gain whatsoever...

 

This is similar

To howhigher end graphics cards can process at 4K since they have headroom, but then display at 1080p. Just because you show it at 1080p doesn't mean you get more performance, quite the opposite you get less in favour of better detail (that would be opposite the OP's case)

Carlos, help me out. Tell me how to do that. (Please be specific.)

 

Thanks.

I'm certainly not going to argue that.  I was just speculating why some claim that P3D runs better in a window than "full-screen" (when, in fact, "full-screen" is also a window).  If I'm wrong in assuming that the game engine down-scales the output to the actual pixel-resolution of the window (which I probably am), I can't think of any other explanation of why the game would run smoother in a "window" than "full-screen".

Sure, you hust need to go into the option page, and in the graphics section at the top right you have a drop down to select the desired resolution.

I'm confused, my FSX doesn't have a drop-down labelled 'desired resolution'. Does P3D? Maybe a picture would help.

FSX in full screen with the half refresh tweak and Prepar3d in full screen with a 30hz monitor both run much more smoothly than windowed mode for me.

@_@   Just hit 60 FPS in the VC going from Payware KBNA to Payware KPNS.   FL 260.  Relatively clear sky.   Wow... never hit 60 FPS in the VC before.  I didn't think it could be done.    It was only there for a few minutes.  It's now floating between 45-50 at the moment.    Something is working.   No stutters either.  I do I have slight terrain blurries when around a lot of autogen buildings but once I get up past 10k everything turns razor sharp at LOD 5.5.      I am noting another little side effect too that is a negative.  FS2Crew sometimes now forces me to repeat myself when issuing commands.   Most likely because the CPU is so busy with processing such high frame rates.    I'll have to do another flight or two to see if the behavior persists.   Guess this is why they don't recommend running full out with no FPS locks but besides that, I am loving this ridiculous frame rate.   And just incase anyone things I am making stuff up or seeing things... *points below*

Thank you. You have confirmed that you are talking about the full-screen resolution setting. As I already pointed out, this is meaningless when running in windowed mode.

Makes me wonder why you bought a 4K monitor...? Specially if you are going to use such low resolutions.

As someone who uses a 4K monitor, I'd be wondering the same thing.  4K got me to get rid of nVidea Inspector and all but internal AA.  At 720p I'd think you'd need some pretty fierce AA...but maybe there's another trick.

You have generated two pages of debate here by saying you are in windowed mode

and now you show a full screen screen-shot???

Don;t know about your other games but P3D for me gives the same frame rate whether windowed or full screen.
