DCS 2.5 slows to 4-7 FPS crawl when rendering 4x 1080p screens (rendering 5760x2160)

[majapahit]

With 1x 1080p screen (a 60Hz TV) on 8600K and Asus GTX 1080

 

I (barely) get 40 FPS with DP,

which apparently is normal

(I tested all possible settings, DS, HDR, shadows etc.)

 

Trees look stupid light green blobs, no detail in the trees, and I think these just don't render as is intended (CPU 40% GPU 80-99%).

 

When I change to my regular setup, 4x 1080p screen in T-formation,

@ 5760x2160, which is 6x 1080p,

DCS 2.5 starts an unbearable 4-7 FPS crawl.

 

Fortunately I still also have my DCS 1.5.8 running,

4 screens, silky smooth and 70-85 FPS

CPU 40% GPU 99%

and actually - Caucasus - terrain way better looking then DCS 2.5

 

So,

 

now what?

 

(I won’t fly with 1 screen)

Disable MSAA in game. Enable FXAA in nvidia panel. Enable deferred shading. lower gamma.

Wow, that actually works.

Who would have thought, thanks you saved the game

 

(Measly 30FPS, smooth and solid)
