A tip concerning minor jaggies / aliasing issues....
So some or most may have figured this out or are smarter than me, but I'm pretty sharp with this stuff and was a bit surprised this was a problem I created.

Having flown a lot of VR, I decided to go back to my triple/single monitor to fly for a while, just to enjoy all the eye candy turned up.

How I judge the aliasing is by looking at an aircraft's antennas, the wire antenna that goes along the top of the airframe to the top of the rudder on many aircraft. That is my visual gage as to whether I have the aliasing highly tuned.

I have a decent rig that allows me to dial everything up, including the Nvidia control panel maxed out.

So when I set back up again for monitors from VR, I noticed that I was getting some of those minor jaggies that annoy me so much. Like around the edges of water, and the horizon, I think you know the type of little jaggies I mean. when you bank the aircraft they sort of come on go on the horizen line and along the edges of water. Also some of the tree shadows glitching a little.

So of course people talk about some Nvidia Inspector useage and settings, and also the sharpen settings in the options menu, so I played around with those, and just never could get it right.

Suddenly I remembered a setting I had changed, and that was the FPS limit in options menu.
Normally on all flight seems I keep that around 60, as a somewhat general consensus is 60 fps is the sweet spot, many argue that is the limit that your eyeballs and brain stops detecting the difference. Anything above that, for the most part, is negligible to your brain. (THIS IS DIFFERENT FOR DIFFERENT PEOPLE, SOME CAN NOTICE, OTHERS CAN'T. BUT AS A GENERAL RULE, 60 FPS IT IS FOR ME)

So I had decided last week to let it run unfettered, and was getting about 136, down to about 60 in heavy AAA areas in the PWCG.

Suddenly my brain clicked.

I remembered the setting in there concerning the game adjusting the graphics to maintain your target FPS you set.....

So I changed it back to 60 fps in the options, restarted, and lo and behold my beautiful non-jaggy wonderful world returned, with no jaggies, and nice, non jittering tree shadows.

So, if you have a bit of those annoying minor jaggies, and see your tree shadows and maybe even a building popping in here and there, AND you have the FPS in options set to run unlimited or higher than your monitor refresh rate, try limiting the FPS to 60 or 80.

As stated, the majority of people won't see the difference of having your FPS above 60 or 80, and assuming your system can maintain on average an FPS higher than 60 or 80, limiting the FPS will stop the system from throttling your graphics as it trys to maintain the higher FPS you told it to stay at.

Just food for thought, maybe it can help someone out. Like I said, most of my flight sims are set to 60 FPS. And as a side note, in games where you CAN"T set the fps limit in the options, you can do that in the Nvidia control panel.

download nvidia profile inspector
go open it and go down to "texture filtering - LOD bias(DX)" and set the value bitween -0.25 and -0.5 (-0.3750 works for me)
apply for all or chose the IL2 profile and apply on that
open the game and enable FXAA 2x or MSAA4x if u pc can handle it
profit
i took this fix from this forum post https://forum.il2sturmovik.com/topic/81003-shimmering-with-normandy-update/
hope this helps :)

also ensure that "texture filtering- negative LOD bias" is allowed and NOT clamped inside nvidia control panel
