Low FPS with this config?

[Tabasc0]

Hello to the community.

I hope you can help me. I think i can have more FPS in DCS with my config. Maybe i am wrong ?

Here is my DCS setup (openbeta) (1)

I've run a "Can you run it" and this is the result with my hardware(2)

I run between 25 and 40 FPS, depending on the mission, the map. 

I've tried to apply some settings to my Nvidia and DCS setups, as shown in "Breathtaking graphics" or some else tutorials.

Do you think these results are quite normal, or am I totally wrong ? I know i cannot run DCS with full details with my hardware, but maybe more FPS is possible.

I know i can reduce the resolution, because for the moment i use the native resolution of my screen : 2560x1440. If i reduce this (to 1920x1080 for instance), i improve FPS to ~50. Can I be satisfied with this ?

I have the latest drivers (Nvidia, AMD Chipset, even the BIOS is at the last version).

Thanks in advance for your help/advices.

Set sslr, ssao, global illumination to off. They improve shadows and lightning in the cocpit, but the difference is not that big and they eat up fps. Set ground shadows to flat. Try water medium. By this combination you should get good fps increase with barely any change in how the sim looks.

Yes what you are seeing is consistent with the state of the game. The "can you run it" databases are worefully optimistic as are the devs own min and recommend specs but this is fairly standard across games.  Should really be "can you start it"

Some suggstions to try - your mileage and tastes may vary!

Sorry Im bound to wholly useless google translete and my much smarter French speaking son is at school -

Textures - is "eleve" high?  If so, reducing the textures to medium will gain you a few fps. The difference between high and medium in newer cockpits isnt so bad. I only really notice it on the older stuff like the Mi8 and Huey but just select high in those cases as the impact in performace is balance out by the lower resolution of the grpahics used back then. 

Shadows - assuming Eleve is "high" - again reducing them to medium isnt too awful and in some cases, I think actually better (tree shadow flicker etc in cetain conditions and on the Normandy map). 

The some view distances got tweaked in the OB 2.7.7.  See how you get on with High instead of Ultra. 

Reducing the grass/clutter (Visbilete Herbe) to 900-1000 will get you a few extra fps on the ground without too much impact. At this time, the 3 foot high grass everywhere is a good reason for turning it off!

Forest visibilty can be slightly reduced without too much of a graphical hit - say down to 85%. 

Global cockpit illumination will cost you 3.-5 fps, try if off to see if you can live without it (some modules cope better than others). 

The Factor sliders can have a big impact in the later maps like the Channel and to a lesser degree Syria but have a more on/off effect in older maps. Reducing the scenery factor even down to as much as 0.6 in the channel has very little noticable graphical impact that I can see and will help keep your frames up (as much as perhaps 10 or 12 extra fps) if you are lowish flying over built up areas. 

Civilian Traffic can have a hit - personally I turn it off as I cant stand the scale speed and cornering on rails without braking animations. Sorry I do not understand what "moyen" means. 

Standard Clouds dont look too bad but the imapct on fps between settings doesnt appear to be too severe in any case. 

Ansiotropic level should, by all accounts, have a very small impact on fps but I have expereinced some slight reduction in performance when flying low over heavily forested areas. For the hit however I would see if you can run it higher and save elsewhere X8 or X16 should be easily possibly and greatly improves things like the runway makings when on the ground. 

If you had a performance hit with the 2.7.7.7 OB, there may be some hope on the horizon that you will regain some fps in the next patch but this is currently based on the expereince of 1 closed beta tester and not official. 

If you can run the game at native 1440P thats what i would aim for. I play at 1080P and its ok but not wonderful. 

Dependent on what maps you fly and what you fly , a few small edits to the terrains/surface folder can help. Removing or renaming the "shrub" ref file will get rid of a lot of small imtems that sit inder the canopy of the forests. It does thin out the forest loos a little but since each of those items have a draw and a shadow, helps stop the fps getting knocked down. This is really a low level gameplay thing however so if you are a jet head and up at 20000ft id doubt youd see much benefit.

Thank you for your answers.

I will check your advices, hope this will improve my experience!

There should be some posts knocking about regarding Nvidia NIS that will really help you. There’s a toggle in nvidia control panel, set your display/system at 4k or 1440 and set dcs settings at 1080 resolution. It gains a lot of frames for me but the jury is still out. 
 

Your GPU is actually good, I had one recently before I upgraded. If you have a search for symbolic link it will help with the VRAM. The VRAM is faster in that version of the card as well. 
For graphics tuning turn vsync off get the best looks/performance compromise and then turn it on to stop tearing/stutters.

Before you do any of that find some of the many tutorials on YouTube for sorting out your windows install for gaming.

Yup, NIS works for me too. But I use it to spice up my other graphic settings with the same FPS.

Altho GTX 1660 is newer than GTX 1080, it only has 6GB of VRAM which is your biggest issue.  DCS needs minimum of 8GB VRAM for high graphic quality.

You should turn off anything that taxes frame buffer like SSAO, SSLR, and Shadows to Low.
