Greatly appreciate the comments. I realize my expectations were high and I see that even the most robust computers may still need some graphics de-tuning to perform well. I will be looking into some of the above ideas and continuing to tweak and adapt. Thank you.

Much obliged! Your settings above look like they come from 2.1? I have updated to 2.1 last week, but am not familiar with some of the new setting options. Here is what I can draw from memory on my 2.0 settings: Textures : High Terrain Tex : High Civ Traffic : Max Setting Water : Max Setting Visib Range : Max Setting Heat blur : Max Setting Shadows : Flat Resolution : 3840x2160 Aspect ratio : 1.77777777 Monitors : 1 Screen Res of Cockpit Displays : Max Setting MSAA : X2...lowest setting but not off; see below Depth of Field : off Lens Effect : Off HDR : on Deffered Shading : ? Clutter/grass : Max Setting Trees Visibility : Max Setting Preload Radius : Max Setting Chimney smoke dens : ? Anisotropic Filtering : off Terrain shadow objects : Flat Cockpit global illumination : ? Tick Vsync Tick Full Screen Max Setting above means those items with "extreme" and "ultra" options were selected. (?) Above means I do not remember seeing such an option...perhaps there are in 2.1 only? MSAA I believe one item this setting effects is the image in the SU-27 mirrors. With this off, the mirror images are nasty, with this at max the images are quite nice. I use the lowest but not off setting. Sometimes in 1.5 with a ton of trees and ground clutter I have to turn mirrors off all together. By all means...I would love to see your Nvidia settings as well. Right now, I have all/most GLOBAL Nvidia settings to "Application Controlled" or OFF. There are a couple, (don't remember which) that are the exception. The Nvidia GAME SPECIFIC tab seems to only point to my 1.5 exe.; even if I try to add 2.0, it seems to default to 1.5 only. So in this tab, I set all settings to "Use Global". In my mind, I have basically tuned off Nvidia and use the in game settings only. Fire away.

rajdary, thanks for the link. I've researched such explanations in the past, but I looked up individual settings. By the time I read about 3 or so different ones, I had forgotten what they all controlled/changed. It's worth another look; especially when the information is all in one place. I'll have to walk through these explanations and test real time on my computer how they effect my sims.

GhostDog, My monitor does have FreeSync and I realize the incompatibility with Nvidia. I actually have been running with V-sync enabled because I get a very noticeable performance increase with it on. Thanks for the ideas; even though I believe I have tried them all, perhaps we can stumble on something I missed.

yes, I do have my power set to High Performance in Windows 10 X64. My monitor is an AOC, 28" 4K.

Thank you both for the advice. I do have all antialising off and my CPU is clocked to 4.8 Ghz and is stable. I will also check the AB software to see how taxed my 1080 runs. But, it seems to me form your respective replies above, that these sims. just push my hardware beyond their limits...requiring lowered expectations and playing with some other options like drawing distance... etc. (De-tune) I can handle that as long as I know it is not a flaw in my system. It is disappointing, but impressive that the sims. can overpower current computer capabilities.

Hello Crew. I have built another computer at home and this one was constructed solely for the use of flying aircraft sims. I have nothing on the computer other than what is required to run DCS 1.5, 2.0 and IL2 Battle of Stalingrad. (BoS) (I have not flown in the updated DCS 2.1 ) My computer specs. are to follow. After about 3 months of jacking around with this new computer, I am disappointed in its performance. With the hardware I have, I expected to be able to run with all graphics settings set to the highest the sims. have to offer with zero/no issues. However, this is not the case. To get minimal stutter in 2.0/1.5, I have to back off the 4K res. and "de-tune" some specs. in the graphics settings. I still see some stutter at these conditions...trying to get completely smooth rendering would require going further down on settings. So far, with the little bit I have fooled around in IL2 BoS, I have noted the same general stutter issues. The above rant is to basically question if these sims. are capable of pushing 1080 cards and the like beyond what they can handle, or do I have a hardware mismatch? I understand there is a relation between the Nvidia Control Panel settings and the internal DCS/BoS settings, but fooling with them only leads to more de-tuning which I find hard to believe is required to get smooth performance. Flickering buildings, shadows, air strips, etc. are also present and annoying. I have done some over clocking and frequency changes using the MSI Afterburner software. My apologies for the long post, but I do appreciate any help/ideas.
