Running P3D with a 2nd display will it hurt performance?

[captain420 3,099]

I'm currently running the sim on a 4K 55" TV. I plan on getting a 2nd monitor perhaps a 1920x1080 so I can surf the net, run PFPX, EFB, PRO ATC, Moving Map or PDF viewer for charts and what not. Would this cause any decrease in framerate while flying in my sim? Since it has to push additional pixels, I'm afraid of a performance loss.

Yes, I run P3D with a second monitor on a i7-8770 and Geforce 1080, running another view.  I find it cuts FPS by about 1/3 to 1/2.

Wow really? That much?

I run triple Dell 27s, 2550 x 1440 Ultrasharps on a EVGA 1080ti. I do not use ViewGroups. 

I stretch the display across all three monitors. I installed 4.3 last night and took a look see night flight at PANC with the Milviz 530, Traffic Global @ 40%, settings low, ASP4, dynamic lighting on. Solid 30fps. A little bit of distortion at the outer edges but I'm not lookin' over there anyway :>)

Haswell @ 4.4, EVO Pros, 32GB GSkill

Works perfect and has for a long time.

Cheers,

Mark

Last time I had multimonitor setup, whenever I would boot up windows, sometimes windows would show up on the wrong display, or sometimes it won't show up on any displays at all, and I couldn't see anything in order to restart, and had no choice but to do a cold shutdown and thats when I destroyed my other monitor, sigh. So I'm kind of nervous of going back to a multidisplay setup. What would happen if I decided I want to use a single display only. Would i have to disconnect my 2nd monitor from my video card or can I simply not turn the display on?

That, I do not know.

I've had no problems regarding display anomalies, yet.

If you run P3D on your 4K TV and use your 2nd monitor to run other applications or undock a few P3D popup windows (not additional views), then the impact on P3D performance will be very small. That's what I do and I see no impact on P3D. But I only run additional applications that have very little CPU use (AS for P3D4 for example) and I often browse the internet during long flights and see no negative impact on P3D.

The big FPS impact usually comes when you undock another view to the second monitor.

What resolution are you feeding the second monitor?

I have a similar setup and agree with the assessment above, the second undocked view will kill frames but the second monitor has very little impact, my specs are in my signature except I don’t list the second Samsung 2330 monitor which is run as an extension of my main. I use it for things like diagnostic windows GPU-Z, Process Lasso, HW Monitor etc, also addons like Little Navmap, GTN 750 etc. When I don’t have a particular need for it I just turn it off. On my system it’s not the use of the second monitor that would effect FPS it’s the fact that I’ve opened an additional app that is now consuming horsepower but I wouldn’t be without my second monitor next to my 4K TV main P3D view.
