Why no DSR?

I have two 980s in SLI, and two monitors, an old Dell 3007WFP-HC, 30" 2560x1600, and a RoG Swift.

If I have SLI disabled, DSR shows up in nvidia control panel.

If I enable SLI, the DSR option vanishes.

If I leave SLI enabled, and disconnect the RoG Swift, DSR comes back.

If I leave the RoG Swift connected, but disable GSync, no DSR.

It seems like SLI, DSR, and RoG Swift, are a "choose any two" situation.

Any ideas? Anyone had similar?!
 
Officially SLI and DSR don't work together.

Some claim they have it working but I've got SLI 970's and a triple screen set up and DSR doesn't work for me.
 
DSR works with SLI as long as I don't have the RoG Swift connected.

I haven't actually tried disconnecting the Dell. Might see if that works.
 
Dar is working on my 970 sli setup with custom resolutions as well (72hz). Monitor is an aoc super widescreen.
 
I have heard some people say that depending on their native resolution (i.e 2560x1080 works, but not 2560x1440p) of their setup they can either get DSR or not.

I would think it would be fixed in future drivers...

I don't think DSR can do its thing if you're outputting to two separate monitors unless they are in clone mode.

Only one monitor?

Yes , I have another but usually just keep server connected to it most of time .

Tbh I prefer massively stupid frame rates over fidelity . Not being able to see those frames is a bummer but feeling them is enough for fluididity

I agree, since going to 1440p144 and Gsync I would never go back. I'd prefer a 1080p144 monitor to my old 1600p60 monitor, which I never thought I would say.

But there are plenty of games that I max out with 980 SLI and still hit silly frame rates.

L4D2 with DSR would be fun for example.

Yea , I mean if I fount a great deal on gsync with higher res I would upgrade , but having less than a year ago bought a IPS 1080p monitor at the wrong side of 200 I have a harder time justifying it to myself over actually hardware.

Will try downsampling a lot more with DSR to move the bottleneck from the CPU at this res I think tho
