Hi I try to keep the first posting in this thread updated, I also added graphs where you can see the items that gave my system the biggest improvements. Of course your miles may vary. I did not use Atlas or any other preconfigured/debloated install because I wanted to decide for myself which functionality I disable and I wanted to stay in control. The end-result may be similar, I am not sure. I have seen some videos on comparing installs like Atlas and tbh was not regretting I went the long route. Whenever there are new thoughts or things to try I will add them to this thread and once in a while I will update the original posting with a list of my most recent changes.

Thanks I will check it out. Maybe it will be the solution to a weird issue I see in latencymon.

CH-47F Development Progress | A-10C Pilot Model | AMVI Tournament
Ready replied to Graphics's topic in Official Newsletters
Nice one! Looking forward to the pilot body for a long time! Would be great to get additional visual improvements from within the helmet like moveable visor, the overlay of the visor and maybe some additional symbology. -
I killed the process and the speed stayed the same, but haven't restarted yet. Not sure yet how it behaves.

Mouse Polling Rate Checked the polling rate of my mouse and thought it was still set to the lowest when I configured it last December. But somehow it was restored to its original 1.000Hz. Readjusted it to the lowest value. Logitech G Hub needs to be removed again, but will have to see what that does to the polling rate. https://www.clickspeedtester.com/mouse-polling-rate-checker/ Thanks @GPatricks for sharing the link!

Good it helped! With regards to what should be realistic; I once saw/heard a comment somewhere that IRL you look on top of the dash/UFC and should be able to see some screws/bolts or something like that. Can look it up but would take a bit of digging. I did not bother since I just move the chair to where I like it. I don't like bending forward and look up to peek into the hud, I much rather just have it lined up when I am sitting straight. Call me lazy

Set a Hotas binding to your seat elevator. I lift the seat up at startup and before take off just high enough so I can see the compass bar above the metal frame of the front dash. During flight I sometimes just adjust it if needed, but rarely have to adjust. This way I have the best possible view of the HUD. I VR recenter when needed.

Hi all is well Busy with some work stuff. Moving to a 9800X3D is a good move, you can never have enough cpu power in the current period. If you have to update your system board as well make sure you have good compatibility so you can do some little overclocking to get the most out of your system.
-
I don't see my rig getting the same improvements as in this video, will hold out for more data.

This is how I did it with (with W10). It really took me a long time to get the new install fully working again with all the various apps and configurations to my liking. If needed I could step back into the old install, which I did a bunch of times. With the dual boot you can take your time.
-
I have installed a fresh W10 on another SSD and copied my DCS also to another SSD. The new setup is working fine and if needed I can still change back to the old setup by booting into it. All still works. One I am absolutley certain I have everything I need in my new install I will scrap the old, or maybe I will just keep it around in case of emergency.

OBS Adjustments Changed a bunch of OBS settings to further calm down its CPU/GPU consumption. Not sure if all of them have any effect, but the combined results are positive. Updated OBS to latest version Added OBS to Windows Graphics Settings | High Performance Excluded OBS from Windows Defender Changed OBS settings in Nvidia Control Panel Anti-Aliasing: Off Low Latency Mode: Ultra Power Management Mode: Prefer Maximum Performance Changed some settings for OBS in Process Lasso CPU Affinity: Core 0,1,2 (away from DCS) I/O Priority: Normal (might change it to High in the future) CPU Priority: Normal (might increase it in the future) OBS Encoding (have to check the visual quality after a couple of recordings) Video Encoder: changed from NVENC HEVC(H.265) > NVENC H.264 (less CPU consumption) Rate Control: Changed Bitrate from Variable > Constant Preset: P5 Slow (Good Quality) Tuning: Low Latency Multipass Mode: Single Pass Profile: High Look-Ahead: Disabled Adaptive Quantization: Enabled B-Frames: 2 Bitrate: reduced to 25.000Kbps (for 2k, in accordance with Youtube Guidelines) Preview when flying: Disabled Replay Buffer: Disabled Aligned Audio Bitrate of all audio tracks (320) Improved Microphone audio quality and volume by adding and adjusting some filters Gain Noise suppression 3-Band Equalizer Expander Compressor Limiter Improved Microphone quality Added a couple more VB-Audio Cables and added one as Monitoring Device from within OBS. This way all the Filters that have been applied to my microphone in OBS also apply to SRS and Discord, hopefully improving quality and volume of the mic. Winhance (new tool to Keep Windows debloated and optimized) Thanks @Reed for sharing. There are quite some interesting things in there. I am too scared to let this tool do all the registry editing for my W10 since it is mostly made for W11 and I don't know what it is doing exactly. The creator mentions that in W10 it has some issues. I like the idea of adding the scheduler to keep things out. It seems to be a great app, but is a bit rough still when you can only switch on a long list of settings or switch them all off. Would be great if inside the categories you can just select the ones you want, so you can test their impact in a more controlled manner. Now you have to enable all or none, which worries me a bit. So I put some of the things on my list to check out.

Thanks for pointing it out and explaining. Changing authorizations for the handful of DCS VR related things seem to have improved my performance. I don't yet know exactly what caused the improvement and I check and reduce the rights that have no effect. I was not aware of running risks when joining MP servers. I normally disable Defender when playing and enable it again after disconnecting. But if I understand correctly this could expose my pc to additional risk. Will look into it further.

For me it seems to work the opposite from you. If I let it loose, I see big FPS dips (to 60-70) sometimes. When I cap fps, the dips mostly stay gone. I am considering reducing the max FPS to 85, to keep some headroom when I play on our busy server. Will tinker with it next time we have a flight night. Another strange and possibly related thing I saw last December was when I adjusted the DCS graphics options to stay just below 90, like 87-88: the fps seemed to be more stable than when I reduced settings to get my fps up at 90. Somehow it seems that a limit is hit somewhere and this limit causes overloads/delays and dips. Unclear what is the cause of this. I have reinstalled W10 since and not tested this again. Will do so soon.

Run all DCS + VR apps as administrator I changed all the DCS related apps I use (Varjo, OBS, DCS, OpenKneeboard) to 'run as administrator' by creating shortcuts and editing it in there. This way I assure that all parts get whatever they need. I think it slightly improved the stability and performance of DCS and OBS, especially the .02% seems to have improved. Set Graphics Performance Preference to High Performance I added OBS, VarjoBase, Varjo Process Server and Varjo Compositor and set them to 'High Performance'. Not sure if it makes any difference, but just to be sure. Yes you are right. I checked. It can only be 90Hz. Thanks

The Aero's Refresh Rate is 90Hz
-
Set DCS's max FPS to Headset Refresh Rate When I set DCS's Max FPS above refresh rate my 1% and .02% are reduced. Setting Max FPS to 90 (Aero=90Hz) is the best setting for me.
-
Ah okay. Will test and post my results. Nice video!

Update the DLSS preset used by DCS to remove ghosting
Ready replied to sleighzy's topic in General Bugs
Yes if configured correctly it shows up in my VR and in the desktop mirror. Bottom left corner. I am not using the registry entry so can't help there. I am using DLSSTweaks to enable/disable. -
DLSS ON vs DLSS OFF? For me there is a huge difference between the two. I don't see a video when I click on the image.
-
What is it exactly you are comparing? I will run the same test just to compare if I see the same.

What are your MSI Afterburner settings for the 4090? I am currently on +100 Core Voltage, +50 Core clock and +700 Memory Clock. I sometimes run Core Clock on +120 and Memory Clock on +900, which also seems to be sweet and stable, but I had a few crashes a while ago and I think it was caused by this OC (but it was with my previous W10 install) so I could experiment with upping it again..
-
Nice! So with your setup you don't really see a difference between 35ppd and 39ppd? I will check the same now DLSS4 is here. Which Quad Views application do you refer to? I am using Mbuccia's QVFR and have OpenXRToolkit running for the performance overlay and some post processing effects sometimes. When I enable Turbo Mode inside OXRTK I don't see any difference in performance on way or the other. Why are you automatic vertical sync and motion smoothing? For me that costs a lot.

I don't think my system is horribly overloaded tbh. I believe I still have a lot of headroom in the 9800X3D, even though DCS tells me I am CPU-bound and it somehow has no way to make better use of the CPU's performance. My 4090 is not really doing much during the quick testruns (I start the stock A-10C Marianas take off mission and keep the Hog standing there). I keep my headset on my desk and I sometimes pick it up to look around and check visuals. But the measurements are always done with the headset on the desk and VR centered. During these measurements the VRAM is relatively low I think. I will check VRAM in future tests when I have removed a bunch of images from the various Tabs in OpenKneeboard. There is about 80% of images I guess I don't not really need or use. Unsure if it would help to clean them up, as you say it does not do anything else than consuming some VRAM and I do like having them at my fingertips, just in case I need something. I have done a clean Windows10 install a couple of weeks ago and stripped it to its underwear. I am still working on finding more ways to further calm down the OS, but it is pretty silent already. Besides DCS I am running the following applications; Process Lasso, WtabletServicePro+children, VoiceAttack, SRS, OBS, Varjo Process Server+children, Simhaptic+DCSRealistic and OpenKneeboard (in various profiles with one or two kneeboards visible). I am checking these apps one by one to measure what is their impact in this mix. With regards to the OpenXR runtime; I am still using Jabbah's since there hasn't been a better known way for me to get OpenKneeboard to appear in my recordings. I will check in with him to see if there is anything to look at. It is unclear if he is still active, our last contact was beginning of 2023 and his last release was about that time, I had his last beta. Unbelievable how time flies. I see our chats on OpenKneeboard date back to 2022 when it was version 0.1.2.180. Where does the time go.. I am also still using Mbuccia's QVFR. Have not tried Varjo's because it won't show OpenKneeboard and I can not manually adjust the peripheral settings for example to get the most out of the system. When I don't have OBS running and OpenKneeboard is loaded the difference between hidden and visible shows a difference of a couple of FPS. I will run more tests in various DCS performance settings and configuration states to get a better picture of my system. (I just noticed that when I close and reopen OpenKneeboard the desktop app does not open in the screen location where it was when I closed it. I also noticed that when I update OpenKneeboard somehow my VR settings like the size, position and orientation of the Virtual Kneeboard gets reset. I will check your help thread and put a few items up on your github if it is not already on there.)

Further optimizations I am playing around with a couple of things at the moment: DCS Object Shadows Flat <> Default. Nvidia DLSS 4.0 Profile J <> K. Combinations of DCS PD (1.0, 0.9 or 08) <> DLSS Performance, Balanced, or Quality <> QVFR Focus_Multiplier (1.0, 1.1 or 1.2) Combinations of Sharpness in DLSS (currently .3) <> Sharpen_Focus_View in QVFR (currently .5) OpenKneeboard Single <> Double Kneeboard. Check if there is a performance difference. Only opening the Kneeboard when I need it during flight and keeping it closed otherwise. Having it open costs about 3-4 FPS and a 5-15% hit on the 1% and 0.2% Reduce amount of images in the Kneeboard to reduce VRAM. (thanks Fred for the tip). Quad View Foveated Rendering Changing the dimensions of the focus section. Make them just large enough not to notice the focus section moving around. Currently both at .35 maybe reducing the vertical and increasing the horizontal. OBS I usually fly with OBS enabled. So I will start running tests again with OBS enabled. Disabling Desktop Preview. I always used to have the Preview enabled, will start disabling it after I checked that it is working. Adjusting bitrate. Currently possibly set too high.
