triple monitor FPS vs. single monitor FPS

[fitness88]

There is a big loss in the frames per second when going from a single monitor to using triple monitors. I've read many posts regarding fps but the amount of screens in use is rarely mentioned. I have an older system, 8 gig ram, intel core 2 quad, GTX 750ti 2gig vram. In single screen I get 50-80fps using most graphic options set at near 75% max. However once I go to 3 screens it's a 50% drop using graphic options set to mostly the lowest settings except terrain and objects set to high.

 

Is there a setting in the Nvidia, 3D settings control panel that would help...besides a newer computer.

 

Thank you.

Not really. This sim is very demanding. I've found I need something with more balls than my 970, I'm maxing out it's VRAM, not to mention I'm maxing out my 16gb of DDR3. If you wanna play with 3 monitors/4k monitor you're going to need more horsepower.

 

If you're using the default 3 screen option I'd recommend against that, it's harder on frames than a single large viewport and it just looks weird.

I find the single viewport has poor graphics especially on the left and right screens but yes it is easier on FPS. Using 3 viewports I get excellent graphics however at the cost of lower FPS.

just bought another 2nd hand 24' WUXGA screen left to my 40' 1080 TV, and right my other 'old' 25' WUXGA screen, underneath I have a previously acquired 24' 1080p touchscreen, where my older one began to suffer from bleed through

 

went from 100 fps 1screen to 35 fps 4screens,

my guess is 50-70 fps triple screens, which wouldnt be too bad would it.

 

my 4 screens really run like 6screens since 1 is underneath the triple row requires a full 6 screen rendering with losses left and right bottom

 

Also not really triple since 2 screen are WUXVGA 1920x1200

 

not too bad, running a GTX 970 @ 100%, CPU 60% w. overclocked 2500k

 

my next upgrade would be a GTX 1070 or 1080 but that would drive VR, if coming VR will have better performance

 

most maxed out, trees @ 0 though, dont like popping up trees (you see shadow blotches now, no trees, you see the airport and town trees), and that took care of avoiding possible lower fps.

 

I think you biggest problem in you setup is your GTX 750ti 2gig vram right now, that or a whole upgrade

 

my NVidia Inspector is set to 16xQ, FXAA on, Anisotropic 4x texture quality PERFORMANCE which looks good on a center 40' TV and smoothens out possible microstutters (VRAM hiccups), all other glitzy Off,

 

looks pretty good (a tad less than a GTX 1080 maxed out of course)

Its not surprising your framerate is dropping. Not only is there now 3x the pixels to draw on, there is also a much wider field of view, so more things are in view. Also, with only 2GB of memory on the graphics card a single 1080p monitor is going to be fairly close to using all the memory available. If you drop the resolution you'll see the rates improve again. You probably need a beefier graphics card here.

I need a beefier system for sure!...which is on my short list. But I am surprised to read that users with top systems including a GTX 980 - 1080 V-card are also having problems as well when options turned up...not sure if they are referring to 1 or 3 screens.

There is no going back to using 1 screen once you've used 3.

 

As for dropping the screen resolution, are you referring to windows screen resolution or game option resolution?

I used to run 4 screens from a Single 3 GB 7970.

 

You will have to drop some options to get a steady FPS,

 

w/ a 2GB Entry Level Card, You would have to run on mostly low settings. but if your looking for Smooth 60FPS Gameplay, it's not going to happen on that setup

Your GPU simply Lacks the Horsepower Needed to Render 3 Separate Viewports(or 1 wide FoV viewport), and it lacks the Frame Buffer to Render frames at the resolution of those 3 screens.

I hear you...surprisingly I get 30-50fps [triple screen] in all single mission play and in some multi-player missions. However some multi-player missions cause lots of frame stuttering, rain for sure but others without rain sometimes do as well.

BTW, 30-50FPS is pretty smooth.

I have a GTX 980 and struggle to run one screen at med to high settings. I wouldn't even consider 3 screens. Anyway I have given up using DCS until ED actually do some optimisation rather expecting its customers to throw miney at hardware just to get the sim to run well.

your specs should run DCS fine, there's something wrong with your installation

My GTX 970 ran awful when just installed until after a week I accidentally bumped some USB plugs, after which it ran 100 fps on 1 screen

Hello,

 

If you want multi monitor experience, one big monitor for DCS and one for gauges gives best FPS. Adding the third one is where it starts dropping fast. I run 4 at 6000x1920. I have an old i-3779k and original Titan. I am smooth in flight. Big slow turns will make it chug in a helo or taxiing, but I just ignore it. I have to say I love the huge screens and run it approximately life sized.

 

I'm not into combat anymore and just enjoy my flights, so take it with a grain of salt...

 

Best of luck with your rig,

I had i7-4790K mated with 980 and ran 3 1920X1200 monitors *and* two USB Lilliput 8" just fine. Granted your CPU is lower and Not sure how much memory you have, but something seems amiss.

I recently upgraded, but I still have my GTX 970 on 3 screens @ 6020x1080 and my frames were good on highest settings. I used to run on a i7 2600k. Grant it, my 970 ran at 99% but not really a problem.
