Unusual multi monitor question

[klem]

I am running four screens, three in surround and one below for instruments. GPU is GTX980 o/c. FPS is mid twenties on ground, 30-50 in the air.

 

I would like to improve my fps and add a fourth screen over the centre ones for a forward/up view.

 

I have a spare GTX570 and would like to run the top and bottom monitors on that and the Surround screens on the GTX980.

 

Does anyone know if this is possible with DCS?

 

I can define left/centre/right/bottom/top monitors in the lua but I don't know if DCS will play with two cards in this way. Hoping someone can give ideas before I start pulling my monitor racking apart to get at the PC :helpsmilie:

DCS doesn't recognise multiple GPUs, afaik

Running my rig (on win7) with multi GPUs (not interconnected).

Add the "new" monitor added to win desktop, arrange total layout to the lowest possible area to render. Then push the assigned viewport to the area of choise.

Select the lowest possible screen resolution you can coop with for the port assigned to the 'external' GPU.

Used to use SoftTH to further adjust render/monitor but currently skipped that.

It will have a fps impact but the quiz is how much

 

(Edit: not using sorround setup though)

Thanks Gus, so it seems DCS will handle the separate GPUs, I suppose according to the Windows arrangement. I hope to find time next week to try this out. Another worry was that the GTX570 might not like the same drivers as GTX980. I will investigate and make sure they are both happy with the same drivers (570 is currently in my 'server' pc but I can use an old 480x for that.

True but the questions is also where the rendering take place, under SoftTh I was told it was on primary gpu only but I dont remember if that was the app or dcs limitation, guess the former but not sure. Have an older 7970 with 6 outputs (4 connected, main view, mfds and cdu) and a legecy 3 head with currently only one monitor ( cloock viewport) connected.

 

My framerate is about the same as yours (25-45 fps) so I guess that an extra top view might be hard in std hd res.

I am using 3 1920x1080 monitors in Surround, on a GTX 970 as one screen of 5760x1080 in the monitor setup, and one 1280x1024 monitor running on the built in intel HD4000 graphics chip with no problem, and getting 60fps, which is the max the monitors can run at.

 

I have the 4th monitor to the right in the Display settings setup, with the top aligned with the main monitor. Physically, the screen is below the others, and for various reasons is inverted - although this has no affect on the settings.

 

You should do whatever uses the least ram (ie the lowest combined width x height).

 

Adding a further monitor would just mean making sure the gui had the correct settings for width and height.

Soooo... it does recognise multiple GPUs? Or only doesn't recognise SLI/Crossfire?

Hello,

 

SoftTH no longer works with DCS in DX11. I truly miss it. I keep hoping someone fixes it.

 

Better performance and adding another monitor? Wishful thinking. :)
