How I can set NVIDIA Control Panel for i9-9900K, RTX2080S, 32GB RAM

[Molnija1985]

Hi Guys,

 

first sorry for my poor English. I have a new account on this new forum. Please how I must set Control Panel NVIDIA, so that I enjoyed DCS to the fullest! Of course I want to balance a lot of FPS and at the same time high quality! I know in NVIDIA settings are various settings, which are unnecessary, as they are controlled by DCS ...

 

Please can you advise me what to set up in NVDIA Control Panel?

 

My HW spec:

CPU: Intel i9-9900K

MB: ASUS Rog Strix Z390-E Gaming

RAM: DDR4 Kingston 32GB RAM

GPU: ASUS Rog Strix Gaming RTX 2080 Super

Monitor: 1x 27" (1920x1080)

 

Thank you

Molnija

I went with Spuds settings. 

 

 

Also a guy named PointBlank that is very helpful.

 

 

Hope this helps you.

Hi Guys,

 

thank you so much for you answares. I set my NVIDIA as follow:

* translate from Czech to English:

- Vypnutý -> Disable

- Zapnutý -> Enable

 

 

After setting I have little problem with smearing objects....if I click on F2 (External view) and rotating around object (aircraft) so object is smear.

 

 

Please can my help:

 - how I can prevent blurring of objects? // EDIT: ouu ok, If i disable Motion Blur in DCS, so this "problem" is resolved

 - please can you see my NVIDIA setting and tell my whether is all ok, or can i apply any change to better quality?

	Thank you, and sorry for my poor English   Molnija

What speed is your cpu running at?

I have a very similar rig but with a 3080, I play in VR but at 1080p you could have most settings on high in the game.

Try these settings for highest performance.  Note that screenshots cannot capture FXAA unless you are in Window mode and press Alt+printscrn.  Set your resolution accordingly (1920x1080).  This is a good place to start.

I’d put trees to max, looks much better on the Syria map. Also, water to medium if you fly over water and civ traffic on (makes the map feel alive)

[Glide]

Yes, these are quality settings you can adjust depending on the amount of VRAM you have.  I have 11GB on my 1080Ti, but most of the new cards have 8 or 6gb.  This limits the amount of eye candy you can push through your card.  I find since I don't spend much time down near the ground in helos or with Combined Arms, I can turn off all the ground goodies.

Working off the premise that the shader cache implementation is having issues, I decided to shrink my Visibility Range, Preload Radius, and Trees.  The idea here is to minimize the amount of textures going through the mill while still keeping enough quality to make it visually pleasing.  For now, these should give you the best quality/performance balance IMHO.

 

Update, Water is not impacted by the shader cache issue, so turn it up to High to get rid of those flickering cloud reflections.  I leave it low because it's ugly no matter what I do.

 

One more way to squeeze a bit of performance out of these settings is to set Res. of Cockpit Displays to 512.  They are still quite nice at 4k with these textures. YMMV.

These are a higher set of settings with the same approach.  They ran very well for me today, and they may be preferred if you fly the WWII kit.

It looks like Anisotropic Filtering and Trilinear Optimization are not aggravating the shader cache issue.  I have not seen any stutters by adding 16x Anisotropic Filtering in DCS settings, and Texture Filtering -Trilinear Optimization ON in the Nvidia control panel.  This improves the textures. 

[Glide]

One more thing to add, since we can have Anisotripic Filtering and Trilinear Optimization again, we can turn the Water up to High and have that look a little nicer.  That's the stutter-free recipe.  Cheers!

[Glide]

Some math to explain why this works.  Assuming the DCS pipeline is working as designed, you can think of the shader cache as a set of gears.  They will run the exact same way each time unless you change something.  As soon as you add AA to the textures, you spin the gears of the shader cache.  When it's on an HDD, it's awful, but on a SSD not so bad, and in memory (shader cache off) smoother but still stuttering (stripping gears).  This is a multiplication problem.  Add more AA and you get, not 10% more spin, but 2x and 4x more spin.  Basically, AA makes the pipeline see more complex pixels and make more shader calls.  Now look at the pixel counts and compare the amount of pixels we are pushing through the pipeline each second.  This is why FXAA is the best strategy (until ED rolls out their planned upgrades); it let's the shader gears do the least amount of spinning at these high resolutions. 

 

Now I am turning off the FPS counter because that way lies happiness.

[Glide]

If these theories are correct, turning down textures and resolution should take the heat off the shader cache.  By the way, I can get stutter free performance with 4x MSAA, AA-Gamma ON, AA-Transparance = Multisample, MFAA ON, and all textures High at 4k.  It just brings my FPS down to below 60 a lot.  Still fine with me, but not enough for VR.

SSAA x2 gives much better framerates than MSAA x4 with HIGH textures at 4k.  Set DCS SSAA to x2, MSAA to OFF, and NCP AA-Transparancy to Supersample x2).  Framerates were almost good enough for VR IMHO. 

[Glide]

And, if you want the turbo experience, turn off all shadows.  Not so visually appealing, but FXAA with shadows off and textures low is as fast as you can theoretically go at any resolution.

[Glide]

I've been testing out Low Latency Mode = Ultra with Vsync OFF.  Nvidia recommends it.  Seems to work fine.

 

BTW, your 2080 should have Reflex mode which is better than Ultra Low Latency, according to that article.
