Ray - been following your updates, and changes. Thanks for posting this stuff. I too have made small changes to things I recommended earlier, and I am also getting improved performance with last update. The biggest change I made recently which really seemed to help, especially with Syria was setting MFR "Max Frame Rate" via NVIDIA control panel. I took the lowest FPS I get in Syria, at about 2500 feet, above a populated area, with my MAV display and TGP active as my baseline of about 55 fps, sometimes as low as 40. I then set MFR to 47. All maps, and scenarios have improved. Most notably I rarely get stutter now, especially on Syria. Thanks for all the detail you are sharing.

I know this has been beat to death. I am not getting a massive FPS loss, and I am not a 120 FPS system guy. However, I know folks are having issues, and I was looking at some more NVIDA tweaks. I tried one more (along with others that contravene other advice!!!) But, I want to focus on the one, that I think had the most impact. Max Frame Rate. In other games, I run 60 to 120 FPS no problem, in DCS currently (and in 2.5) doing good at 50 to 90 - currently 45 to 60 ish 2.7 Syria. So this tweak is to drop about 10 or 15 frames below what you normally average, and set your Max Frame Rate there. This does not affect other games like Borderlands 3 for whatever reason. I did this mainly for DCS, and I can confirm using an FPS counter, it pretty much stays right at 47 - before it would float between 45 and 60+ on Syria. Higher on other maps. However, no stutter, and rock solid performance. I hate it that another tweak I was using, kinda gets over written on other things with this tweak. But I would be interested in knowing if folks set this 10 to 15 frames below their best in DCS if it helps them or not. If it does, I will go over the other tweaks I tried (that are somewhat different than other advice I have followed) and we can check those. I definitely got some smoother better performance with these settings - but I think MFR is the one that others can try and get a measurable verifiable benefit or not.

I only cuss once (Sh*!!), a lot of "comon bro!!!" - oh "hell bro!!" - speaking to boom operator. About 9K pounds transferred. Had to hit the straw a few times, but mostly smooth. I kinda get loud, might overdrive mic, check your volume!!! It can be done, as all those before me have said. Practice, practice, practice. Read, Read, Read. Check curves, check controls.

You know, it is like a water bed. You have to stop moving around so much on take off and landing, then that will calm down. Seriously though, since it is rendering under all land masses, if you (we) just set our water detail to low, then we should get a performance gain??

I fly the P-47D for the same reason I fly the A-10C as my main sled. Different, labor intensive, has unique strengths that other aircraft don't have and once you learn to leverage them effectively, your impact on the battle field is immense. Don't get me wrong, I am learning the F-16, and appreciate the airframe for what it is, and truly enjoy the speed, the model, and what ED has given us with the F-16, so it will become my "other sled", just like the P-51. For whatever reason, I really enjoy being able to tweak the throttle/pitch on a gun run in the P-47, and letting the torque walk my guns onto the targets as I make a pass - sometimes don't even need to hit the rudder or the stick. The engine torque does all the alignment for me.

Well, that is good to know - I didn't realize there was a setting analog for Scenery Details factor - might be closer than I thought. Wasn't trying to be heavily critical, I was going over the settings myself, and wondering how someone "could" do a apples to apples. I wonder if the devs could map it for us, or if it is even possible? I didn't take near the hit some did, and the 2.7 screen is my current settings, with very little frame rate loss. Except for Syria, but Syria always loaded my machine in 2.5 and 2.7. But I am Track IR, with 32 GB of RAM running from an SSD, with an SSD page drive so hard for me to say how much 2.7 really hit me and under what conditions. But overall my experience has been pretty good for the increase in detail etc.

Own both titles. There is only one of them that gives me the full P-47D as I would want it to be. They both however scratch an itch, and they both have their place.

An observation about your statement of "same settings" The graphics settings in 2.5 and 2.7 are not identical. The most prominent changes which did not exist in 2.5 are the settings for "Forest Visibility, Forest Details Factor, and Scenery Details factor". When you do apples to oranges between your two images, the 2.7 image shows softer edges to the forests, and more individual trees are visible - so this is not a "apples to apples" setting. You would need to set the new "Details Settings" and SSAO! to match (if even possible) the old 2.5 settings for those details. So it isn't really a straight up 2.5 better, 2.7 worse comparison, until you figure out how to modify new 2.7 settings to be as close as possible to 2.5. 2.7: 2.5

I had resigned myself to never getting this. Mild cussing, be warned. Yeah, you would cuss too with turbulence and other factors jacking with you for hundreds of attempts to kiss the BOOM - and then one day viola!!

Good news - not sure if I have an answer for this, but in my Squadron, when we run "Operation DCS Liberation" - with a lot of AI activity, like on the TARMAC for take off, everyone experiences frame rate getting tanked. We are not sure if it is AI processes hitting our CPU's or what. Not sure if related, but if the Bomb Drops, and the formation of AI B-17's are all mashing your CPU to do their calculations etc it MIGHT (and I stress might) be related? Others smarter than me can comment and clarify.

@Flappie Unfortunately I have not been able to reproduce this. I should have saved that track the first time. Apologies. I would just "close" this. When/if it happens again, I will keep the track file. Regards,

That is awesome Ray! Glad it worked. I figured we should be close in performance based on your specs. I am sure as ED gets all the data, and further optimizations occur, we will get some more life out of these "mid range" systems.

What @acerus77 said. The throttle alone will generate enough torque, depending on pitch and supercharger/turbocharger settings that it will "sway/roll" the nose around. Once you get used to it, and have some type of Hat trim switch, you can set it nice, straight and level. Cruise with ease, hands off. If you notice, there is a TO (take off trim) setting, which offsets engine torque with rudder trim - same type of theory in flight.

Yeah, I can recreate it. I forgot to grab the track file. Just a generic AAR I made to practice on Caucasus, so the next time I practice will see if I can trigger that again.

Think this is the right place, but pretty sure this isn't intended AI tanker behavior?

That's crazy!!! I bought mine at Amazon for $250.00 about a year ago. Don't think my card is a Ti, but not really sure what that means either . . .

Nice catch - but now I am sad. I know what to look for. Before I was blinded by ignorance . . . no more. Thanks brah.

@rayrayblues - here are my specs, and settings. Currently getting better performance under 2.7 than I had under 2.5 with a 1660:

Aiigghtt! Give me a day, gonna have to take pics of the BIOS (reboot), the other stuff I can just paste and dump. Direct Message or just lay it out here for everyone to see?

Sir, I have a 1660 Asus TUF OC, and I have had good luck with 2.7 I would be happy to run through my specs in detail, how my RAM clocks are setup, drivers, configuration etc. if you think it would help.

Have an SP mission, starts off the coast of Syria, flies in, coordinates with JTAC, attacks Fan Song SA-2 (S-75) site. Built it when Syria first came out. When I adjust video settings, I save them to one of the 3 "save" video settings options. For any test I did under 2.5 and 2.7 I start this mission, follow the same path, turn on the same sensors, run the FPS counter and do the same actions, i.e. turn on MAV seeker, and TGP and slave them to target area. I fly over forests, towns, and will maneuver to look at them. I record it, with NVIDA capture. I also run the NVIDA advanced FPS counter, that shows frame delay, and other metrics. When I post something up here, it is exhaustively tested, under the same conditions, using one of 3 video presets in the settings panel of DCS. I would say you are correct in some instances, but when I go to the trouble to post in these performance reporting sections, I put some work into it, and use the same conditions for each test.

@Flappie I have the update, but after going through the process I detailed above, I am NOT having FPS drops. Either status quo from 2.5, to improvement in 2.7

Man that is perplexing as hell. Not saying you aren't suffering with this, but my experiences (as detailed above) are the opposite with 2.7 - there must be some common Hardware or Software issue, one would think, if only it could be identified.

I went step by step through this. Specifically I think out of all the recommendations, the "Sharpening" setting under NVIDA control panel being turned off is the biggest one, and set Global for all applications. I have had pretty good performance with 2.7, especially with Syria. I also did a delete of saved games, and restored my config settings, along with this vid - I got a solid 10 FPS INCREASE over 2.5. 45 Solid FPS with Track IR, low level flight over Syria, with the A-10C and left MFD showing MAV seeker, and right MFD showing TGP sensor display. This has always been a frame killer for me. After following this vid, changing the Global and Application specific NVIDIA settings (for DCS in NVCP), and the only difference for myself and the author in the video in settings is I don't run SSXX anything, everything else as he lists. This is with a ASUS Tuf OC 1660, 32 GB RAM, ASUS 470 MB, Ryzen 7 CPU OC'd to 4.2 Ghz, and MvE 1TB SSD. 45 FPS solid, Track IR, his settings, and both MFD's in the A-10 actively displaying video. By comparison, the F-16 with its "simple" MFD displays, I am hitting 60 and 90 FPS with the authors settings above. I would go through this if you haven't, perform the Command Line DCS.exe clean up and repair (or optionally rename saved games folder and let DCS recreate). I have a moderate system, and I have gained in FPS, and smoothness, with ULTRA clouds, mostly high/Ultra/Max settings, on Syria, and A-10C with two active camera displays on the MFDs - this was always a FPS gut punch in 2.5

Do you mean update from a different release, like Main, and not Early Access Open Beta? Or do you mean update your existing Open Beta from 2.5 to 2.7? If the latter, just launching will force an update, or you can initiate an update from the Command Line within the DCS Open.Beta directory using Update.exe. @SkateZilla Has a great reference for how to do this properly:
