Rtx 2080 ti on 3 x 2k monitors

Postby danosti » Sat May 16, 2020 10:07 am

Does anyone have 3x 2k wqhd monitors hooked up to a single RTX 2080Ti .
since V5 doesn’t support dual GPUs in sli

Looking at a single
But curious on the performance of this set up.

Yes, I do.

My Specs:

3 - 2560 x 1440 on a single RTX 2080Ti
i9-9900K
64 GB RAM

However, because I use ViewGroups, I think my bottleneck is the CPU trying to render 3 camera views. The Performance is not great at the larger super detailed airports. I really wish the multiple cameras didn't cause such an impact, because it really looks nice w/ a correctly calculated and configured viewgroup. If using something like NVSurround with single camera or stretching the window across the monitors, you get MUCH better performance, but with distortion as the view gets wider and I don't like the way that looks. I guess I am hopeful that multi-view performance could be improved somehow.

After a crazy amount of work on this topic I have finally solved it for me.

3x 2560x1440 monitors using g-sync (results better than triple buffer)
1x rtx 2080ti, forward monitor and realsimgear Garmin plugged in
1x rtx 2080ti, left and right monitors plugged into the other card (no sli, just using each card by its self)
View groups is working in V5 across cards - best performce (better than 4.3 and 4.5)
At complex airports getting 30 FPS smooth. Away from complex airports 60 FPS.

CPU overhead is real due to management of both gpu shaders and cache but with i9900k its perfectly fine. I’m not over clocking , no need.

I have a few tweaks in nvidia control panel for threads and prioritization.

I’m running OPUS, orbx, spas.next, real traffic, a2a, majestic q400, Seattle x, sfo hd etc.

This is the best it’s been....

Can the second card (no SLI of course) be a different type to share the GPU load? I have a 2080Ti with triple 2k monitors plus Realsimgear GNS430. I have an old 1070 card. Will this work to run one monitor and/or the 430 display?
