Multi-screen FPS questions

[goon3r]

Hi All,

 

After running Eyefinity for a couple of years I'm looking to switch back to 1 large screen and second screen for mfd export. I recently got a 2560 x 1440 widescreen with a second 1366 x 768 screen for mfds but the FPS was poor. In some missions I got mid to low teens and single digits in others usually during battles things get bad. I usually play with heat blur off and medium water. Everything else is at max and I usually run the game in Fullscreen mode.

 

My CPU is a circa 2008/09 CORE i7 920 that's overclocked to 3.8 GHZ and a Radeon 7950. I feel this machine should handle the resolution I'm trying to run here but am being proved otherwise.

 

I'm looking to gauge the feelings of those here running multi-screen setups and set my expectations. I really am not looking to upgrade CPU/MB just yet but am open to any tweaks that can be suggested to make the frame rate acceptable.

What are the Clocks of the 7950, and what are your DCS GFX Settings?

 

I was able to run 4 Screens (Eyefinity Array at 1080P + 16:10 Screen for Helios at 30FPS from a DualX 7950.

 

Upgraded to a 7970 Lightning to use all Display ports, but I keep my FPS Capped at 30 FPS.

 

Also If you havent already tried, Use the Catalyst 14.4 DLLs as they provide the best performance in DCS (previously it was 13.9)

I actually tried the 14.4 drivers you suggested and it seems a little better but I will need to do a bit more testing. My card is totally stock haven't OC it one bit.

 

Is the current DCS engine more dependent on CPU or GPU power ?

 

My GFX settings are below.

Lovely. My thread has now been moved to a forum that has not had a new post in 2 weeks. Perhaps it would have been better to close it.

So I am still getting low fps after updating to the 14.4 drivers in many missons. For example, I just did push 6-1 and spent most of my time in the mid to low teens.

 

Here is my current monitor config and graphics settings. Thoughts ?

 

_ = function(p) return p; end;

name = _('Widescreen + 1');

Description = 'Widescreen + 1'

Viewports =

{

Center =

{

x = 0;

y = 0;

width = 2560;

height = 1440;

viewDx = 0;

viewDy = 0;

aspect = 1.77777;

}

}

 

Shkval = --Shkval

{

x = 2560;

y = 0;

width = 900;

height = 700;

}

 

ABRIS = --Abris

{

x = 3276;

y = 0;

width = 400;

height = 700;

}

 

LEFT_MFCD =

{

x = 2560;

y = 100;

width = 650;

height = 650;

}

 

RIGHT_MFCD =

{

x = 3276;

y = 100;

width = 650;

height = 650;

}

 

Gui =

{

x = 0;

y = 0;

width = 2560;

height = 1440;

}

 

UIMainView = Gui

Hello,

 

first : generally Fullscreen mode isn't recommended with multimonitors. Personnally i always disable it.

 

two : water and shadows are major "FPS droppers", you will see a difference with Water and Shadows on LOW.

 

three : You ask modifications for having a "acceptable framerate", but you never say how many FPS you actually have. Because you can also set to LOW textures, scenes and visibility range :smilewink:

 

And if you exported your shkvall and abris, you can win some fps more by disabling shkvall and abris from your 3D cockpit (for exemple)

I made the changes u suggested with full screen disabled and water and shadows at low. I see only small improvement though.

 

To be clear, I just played push 6-1 and spent most of the time between 10 and 19 fps.

 

The misson starts off mid 30s but once the battle starts its a slideshow at times.

With single viewport you should get bit more FPS than 10-20, that's roughly what I get with 7970 and 3 viewports and I have high settings with mirrors on, only CiV traffic is off and water is medium (similar to yours).

 

I am guessing you are using adoptive AA in graphics setting which kills FPS now... so if you are use Multisampling instead. Also if you don't use Full Screen don't tick Disable Aero in game options, sim runs better with Aero on when in Windowed mode.
