OB 2.8 Bad performance with diminution returns!? 2D

[Jutter]

I feared when downloading DCS World 2.8, the very moment it was downloading! "Please don't have a lot of performance loss" over and over again. Typically, I don't fear performance upsets from patch to patch, my system is aging......... a little....but since 2018 my 2080ti has served me well, and still does! However, we all know how the "major patches", can behave. And with that said, in 2D across the board with my 5800x3D and 2080ti, lost about 20/25% performance across the board, with the exact same settings I had before the update. Now I've been kicking around DCS World settings for the last 5 years now, not saying I am a Pro....but I'm definitely not a "newb". Visually, there is nothing to suggest the major loss in performance, moving clouds? No! Rainbows and Unicorns? No! Angels Halos? No, can't be! There were some mentions of terrain shadows causing it "Flat" or "Default". No, that couldn't be it either, "flat" was always more performance friendly than "default" but I don't think that is it, however side note: The "FLAT" shadows are doing really weird <profanity> now! so that's a downgrade form 2.7! So just kicking the setting around to see if I could find an outlier! Scenario: F-16, genuinely seems to do worse than any other aircraft after 2.8, that is, between the A-10, F-18, and F-14, for me anyways! NTTR map at Dusk, probably the easiest map to run performance-wise. Preface, I do not let my GPU run unconstrained, I have a G-sync OLED, and cap the frames at 60. This is a personal preference! So, I will not be speaking in terms of overall FPS but in GPU utilization! Generally, in this SP mission I built for myself, under these circumstances on the ramp, the utilization is relatively low, won't speak to 2.5 in this instance, but all of 2.7 builds, loading into this mission, or one similar too it, I'll be sitting around 64 to 68% utilization...........pre-2.8! Now...... 86 to 91%, pretty drastic! Like I said, this loss is across the board no matter the map and mission I have built for it! Turn off msaa 2x, which I always have it set too, Clouds from ultra to high.....85 to 89% utilization. Thats weird, never have I went from msaa to no msaa and seen a significant uplift in performance. Soo..... put msaa back on, that doesnt seem to be the issue, didn't gain much from it by being off which is a first! turned clouds back to Ultra, and then turned terrain shadows off all together! Again.....84% to 89% utilization. WTF is going on here!!!! I gained very little from that! Then I remembered! ED felt the need to effff with the cockpit shadows and make them......"more realistic" I guess? That and shadows on MFDS, the overall lighting! I am a total Graphics snob; I thought the shadows and lighting in the cockpit was just fine but that's just me. I always left Cockpit shadows on high for years, literally, never had a performance problem with that particular setting.........unless it was VR, then I'd lower that setting to low. Never had an issue with it in 2D!!! Again....pre-2.8. So, I reluctantly turned Cockpit shadows off to see if I would Gain anything There, Because I hadn't with the other three settings, other than a couple percent. Very Anticlimactic "BOOM" 70% to 73% utilization! Not an expert in Video Game Design/coding, that is to say I dont know <profanity>, but...........I am kind of an expert in DCS world on MY system! I would bet that their damn "upgraded" shadows is killing the performance really bad when it hasn't before!!! Maybe this is just the new "norm" and I have to buy a 4090 now?! I really hope this is a bug or a poor optimization of these shadows killing the performance! PLEASE ED, STOP WITH THIS NONSENSE!

They did say that there is a problem with shadows. I don’t think it’s just Terran shadows but shadows in general. My bet is that it gets cleared up in a patch tomorrow 

[Jutter]

I Hope so mike! fingers crossed!

I am sorry to hear few non-postive and vaulable feedbacks, and I am not sure that ED has a chance to see this thread rather than the patch discussion thread.

I couldn't read the first post. Not that it was too long - but no paragraph breaks did my head in. 

I gather the OP is concerned about each patch coming out taking more resources and causing more performance issues. If so - I think it's a valid concern. I know Vulcan and Multithreading are "in progress". And we can be patient and wait. What we can't afford though is for new features to be implemented that keep taking away the limited resources/frames we have left to spare. (We're quite thin on there as it is, and for many of us - OpenXR has been what has literally saved DCS in the mean time). 

I'm hoping that the performance issues are just a bug and can be fixed in the next patch, and it's not a matter of "extra features mean extra CPU resources used".

I set shadows down from high to medium and all my performance woes were gone.

Turn shadows off for now see how it performs . Maybe next patch will fix things .
