GTX 980Ti in SLI.....Can it run 7680 x 1440 in NVIDIA surround with 3x 27inch monitor

[sashin]

This is my first post in this thread, so i would like to just say hi to everyone here. I have been looking around the web for info on this particular gaming resolution BUT i find more info about 4K Surround or the usual 5760x1080 res.
My specs are as follows:
Core i7 5960X at 4.5Ghz watercooled with EK monoblock for CPU and chipsets, 2x 980Ti EVGA Superclocked+ ACX+, Tagan 1300watts PSU, Asus Rampage 5 Extreme mobo, 16GB GSkill @2666, Samsung SM951 M.2 PCiE SSD 512GB for OS, Samsung 850 Pro SSD 1TB for Games, Western Digital Red 6TB for Movies and Backup, Case Labs Magnum TH10A with rigid acrylic tubing and BitsPower connectors and Aquacomputer components..ie Aquero, Pumps, Reservoir, Temp and Flow Sensors

Will my setup be able to run at the 7680x1440 above 60fps....looking to get GSYNC monitors each with resolutions of 2560x1440. I currently have 3 x 27inch non-gync 1920x1080 monitors (5760x1080 NVIDIA surround) from Asus and AOC. I tend to play mostly FPS ..Tomb Raider, Crysis 3, Far Cry 4, BF4, The Witcher 3, Assasins Creed..
Any help would be greatly appreciated or atleast point me to an article that will give me more info. I do not want to purchase these fancy expensive monitors only to find out that my setup struggles to run it smoothly.
Thanks

I believe the Nvidia drivers allow you to set a virtual resolution which they then scale down from. With that, you should be able to set your existing monitors to 2560x1440 and see how bad it is.

Can't imagine many people have tried that, so let's break it down into how many pixels it is compared to 1080p to get a good guess.

A 4K monitor is: (3840x2160)/(1920x1080) = 4

So a single 4K monitor is equivalent to four 1080p screens.

(2560x1440)/(1920x1080) = 1.78

So a single 1440 monitor is not quite twice the pixels of a 1080 monitor. You want three of them so you want 1.78x3=5.33

So, you are after 5.33 full-hd monitors worth of data, which compared to your current 3 full-hd monitor setup you will be going almost half the speed.

Can you cope with a bit better than half your current frame rate?

As I said at the start, give it a try by fiddling with the drivers. I just swapped to an AMD card so I can't tell you where the option is, but I am sure it is in there somewhere.

That is a mighty resolution, however the 980Ti is mighty too especially coupled with two of them. I think hang on until we see Windows 10 multi gpu scaling at the end of the month, it may just help your decision and make it viable if half your current fps is not.

Agreed...will just probably wait until next month to see if there is any update in this field. I am also looking at curved GSYNC monitors....just a few at the moment and mostly 34 inch panels which is way to big for gaming rigs as one would have to sit 20 feet away just to absorb the whole experience...Looking towards 27inch curved GSYNC panels if it ever materializes. I would hope that at these large resolutions ....GSYNC will help smoothen out the FPS..

Yep will try messing around with the virtual drivers....although i must say that this is the first time i have heard of these setting in the NVIDIA Control panel. Well ....i will give it a go and see what happens.
As for almost half the frame rates....i would presume the GSYNC features would smoothen out the FPS with less stutter...although the actual FPS will remain the same. I am currently getting anywhere between 60-80 fps (average) in the games mentioned above at 5760x1080 res with my current setup although i do get screen tearing at times in graphic intensive scenes in the various games.

It's called Dynamic Super Resolution is an excellent way to test your system, it's a great suggestion by DanceswithUnix. What it does is render your scene at a higher resolution and then downscales the output image to match the resolution of your monitor(s). Running this will enable you to find exactly how it performs at the resolution you want and then take off about 1% for the G-Sync overhead.

Yeah very neat tool to use. accurate for fps

[sashin]

Great, Thanks everyone for giving your suggestions. I will give DSR a go next week when i am back at my desk.

[Obie]

Nice. I'm curious to know how it does

[sashin]

DSR option is not available in NVIDIA Surround mode (Triple monitor). Only available in single monitor modes....
I think i will just get three 27 inch GSync @1920x1080 and be done with it....Playing Crysis 3 with every setting maxed out with Ultra quality settings gives me anywhere between 45-60 fps with my hardware !!

You don't need to run it in Surround mode. Just test the performance in single monitor mode.

If i do that i can only test it from 1920x1080 to 2560x1440 per monitor right ? How do i then get frame rates for 3 of these monitors at the DSR settings to give the some rough numbers at 7680x1440 resolution?

I think you just set a custom resolution in nvidias control panel (the one you are aiming for) and then choose that resolution in game, even though your monitor doesn't support that resolution it will display it in the maximum supported resolution of your current monitor BUT the textures will be rendered at your set in-game resolution providing accurate fps representation of what you would get.

Either this or just scale the resolution to match the same pixel count value as you are intending to use ie.. if x by y equals xy pixels see if you find a setting that matches the pixel count and use dsr that way, assuming the custom resolution gives you that degree of control.

OK I presume that this is done on a single monitor right?...Will give it a go later this evening. Thanks
