Multi monitor setup+SoftTH & low fps

[LVNona]

Hello I'm new but from this forum learn a lot and need your help & advice.

 

CPU: I7-4770 (4.5Mhz overclocked)

Mobo: G1 Sniper 5

Ram: 16GB 2400Mhz S.Kill Sniper edition

Video: ASUS GTX780 x2 SLI

All PC custom waterloop (http://www.dazmode.com/_forum/showthread.php?939-LVNona-First-build)

Drives: SSD 120 + SSD 256 + HDD 1TB

Windows 7 x64 ultimate

Saitek X52 Pro

Pro pedals

 

I used to play only on one 27'' monitor and get average 120fps

Now I want to try multimonitor setup.

 

Monitors: Dell 17 1024x1280 (portrait) + Overlord 27'' 2560x1440 120hz (landscape) + Dell 17'' 1024x1280 (portrait)

 

I connect all monitors to only one GPU: DVI + DVI + HDMI

Another card is connect as SLI (NVIDIA control panel)

 

Windows and NVIDIA wont start Surround (i expect that)

But when I start my DCS World (LockOn) I see available resolution 4608 x 1440

Started - games run ok and frames around 45-55fps. But now my bezels and screens are in bad position.

 

Using SoftTH207alpha_x64

I upload d3d9.dll and config file to DCS World/bin and configure all monitors and bezel distances:

All screens setup at 75hz at windows.

 

My config file:

[main]

renderResolution=4968x1440

nonlocalFormat=RGB16D

keepComposition=0

smoothing=1

debugD3D=0

zClear=0

vsync=0

And now when I start the game I see actual SoftTH enabled because logos comes up at side screens and bezel and screens look ok. But the problem my FPS is dramatically low - 14fps.

 

What do i do wrong?

Do i need to disable SLI and connect side screens to another monitor?

For my $4000 PC to get from top video card and highest performance pc only 14fps sounds disappointing

 

Please help,

Thanks, Norm

try window mode and full screen mode?

[LVNona]

try window mode and full screen mode?

I'll try.

But I read somewhere - SLI doesn't work at window mode.

Is my multi monitor connection look good? Or should I split and connect to both cards?

[LVNona]

try window mode and full screen mode?

 

ok, something strange ;)

at FULLSCREEN all screens shows up ok, but FPS average 18fps

Windows mode - fps goes up both sidescreens shows the same picture - so I have 2 right monitor pictures showing also at the left as well.

Any idea?

[LVNona]

And at full screen my cursor is way away.

At window mode cursor is ok.

Hi LVNona

Try disabling Areos in game option menu .

Hi LVNona

Try disabling Areos in game option menu .

 

Thanks, I'll try it.

What Aeros is exactly doing?

 

I get some progression:

-disable SLI

-move side monitors to second card

and now I'm getting close to 35fps average (highest graphic settings)

If I disable some shadows, medium settings and .... I'll get around 41fps.

 

Is there any other way I can improve?

 

Thanks

Had a similar kind of issue you're having, for a loooooooong time in fact - but Im at the office and cant remember exactly what I did to fix it.

 

Tried a lot of different things, and did find the problem... but I can nearly promise you that the fps you're getting is not what your system should deliver - as we've both got similar set ups.

 

First off; is there a particular reason why you don't expect Nvidia surround and SLI to be enabled? Different sized monitors perhaps? I only ask as mine is set up for surround and SLI - and I never found the need to disable - the problem was with DCS and the way it was trying to treat my monitors, not because of my current GPU configuration.

 

I also remember I had a huge difference in performance between full screen and windowed mode at the aspect ratio I was being defaulted at, for the resolution I wanted - 5760x1200 will automatically default you to a "4.8" aspect ratio, which seemed to give me trouble in fullscreen mode.

 

Are you simply trying to give yourself a wide view across all three monitors? Or are you trying to use the 2nd or 3rd monitors for MFCDs/other viewports?

 

If you're trying to set up MFCD etc etc - may want to look into some of the guides out there

Disabling Aero just turns off some of Window's GUI effects - but you should not have to worry about that. I'll have to double check my settings when I get back because with your setup, unless you've got some underlying problem, you should be getting what I'm getting - which for me, is close to blowing the doors off performance wise

 

My config:

Windows 8 64 bit

ASUS ROG Maximus V Extreme w/Intel 3770k @ 4.5

2 Gigabyte GTX780s GHz Edition

16gb RAM 2400mhz Corsair Dominator Platinum

Running off a Samsung 840 SSD

3 24" ASUS IPS panels with at 5760x1200

Track IR/Warthog HOTAS/STK Pro Pedals blah blah I don't think the rest of my specs are going to matter too much -

 

I get there could be OTHER issues - but assuming you have a healthy OS and normal DCS install? Your rig should be handling DCS just fine - You've got the horsepower - but DCS can be a challenge, simply getting it to run across three screens - one wrong setting, and you'd wonder if you'd got 560's instead of 780s.

 

And for me personally, it had nothing to do with bottlenecks, on MY end - it simply was about the wrong aspect ratio/monitor setting/ or the way DCS treated my overall screen space - once you find it, you shouldn't be anywhere below 55fps.

 

 

I'll check what I had found once I get out of the office see if I can replicate my own issue (just hope I can fix it again :D)

Hei thanks buddy ;)

I would like to see your SoftTH, options & monitor.lua settings.

 

My idea is to extend angel view - make it liitle bit more realistic ;)

Bad DCS dont have proper soft for setup everything at one place and you all the time need to jump from one place to another and so on ....
