Thanks a lot for sharing your setting! Very interesting approach, I will definitly test this. Regards

Fix the issue of @durka-durka if you are that wise. Page 1.

Oh there are so many ways to FU the system, this can be achieved easily, even with a 4090.

Not sure if this helps or if you have set these things already but I have also followed the steps 1-11 below, and I can imagine that point 4 could be your issue: Rebar enabled XMP Memory Profile DCS Latest Open Beta version 32GB – 64GB Pagefile (Virtual Memory) Windows Game mode OFF Windows Game Bar OFF Windows registry Holographic PreallocateVirtualMonitors set to 0 Windows Holographic Shell Stopped ("Go to Computer Management → System Tools → Performance → Data Collector Sets → Event Trace Sessions. In this list, find HolographicShell, right click, and choose ‘Stop’.) Windows Power Management Ultimative Performance Windows Graphics performance for DCS set to High Performance. Variable refresh rate ON HAGS OFF The info comes from this threat:

Thank you for posting your settings. I can see that I am not too far off from you. As said I run the G2 on 60Hz now including FFR and its quite solid. Need to test further in MP and stressful missions. In case it fails I will sacrifice the ultra clouds I guess. Maybe there is even room to crank some things up, but this will be done later on after more flight hours. For now its a good starting point. Thanks to all who helped me getting some clarity in this setup-jungle!

Found it. this is what it looks like over Damascus with 60Hz. And here you can see the FFR at work, the outer, not seen part, is low resolution. There are some spikes here and there, but nowhere regular and every second.

What kind of tool you are using here for fps and frame time check? I could make a test too.

Fixed Foveated Rendering. You can enable it in the OpenXR Toolkit by mbuccia.

Hey man, I think you were right from the beginning. I was disabling DLSS, only DLAA ON and 60 Hz, downed the gamma and here you go. best quality, best clarity and from all the testing today (nearly 8 hours) by far less stutters. The 60 frames stay like a tank, no matter what comes or happens. I do use FFR on wide and performance as I cannot see any downside. Concerning the 60Hz, I notice the flickering only in the menu and the WMR Lighthouse Area, so absolutly unimportant. Ingame it is not noticeable for me and even a better experience because of the less or no stutters. Also 90° looks out to the window does not hit performance or smoothness, something which was a pain since years. I guess I keep this for now and will have a look how it behaves with longer missions. Thank you for your help and time.

ok... after some testing - some more data to share. With my CPU-GPU-RAM combination (see signature) and paired with a standard G2 I find OXRTK definitly better than QVFR. At a free flight in a Mi-8 over Damaskus (Damaskus Taxi mission) I achieved following results: QVFR: 65-70 fps at airflied, up to 85 fps in open area and 75 - 80 over rooftops in city. CPU frametime ~ 14,8ms and GPU ~ 14,0 ms. Settings with QVFR: DLSS + DLAA, Quality, PD1.0 OXRTK: 75-80 at airfield, 90 in open area and 85-90 fps over city. CPU frametime ~ 7ms and GPU ~ 8-10 ms. Settings with OXRTK: DLSS + DLAA, PD1.0, Quality, FFR wide Performance. I can see less stuttering and get a more smooth flight. GPU headroom is somewhere ~ 2 ms. Approximately same goes for the tests without DLSS @ 60Hz. Seems like a RTX 4090 is still bottlenecked by a 5800x3d, but its not much. As I am running mine at 80% powerlimit it might be this 3-4% loss to come equeal. Nevertheless there is no issue like that with DLSS. Even better now would be to set 60Hz but I can see the flickering... not sure if I can get used to...

thanks a lot!

Strange... I used OXRTK in my Radeon era and now two weeks with the 4090 without any CTD. To me stuttering is alot better with turbo mode enabled. But to be honest, I did not try running VR without the OXRTK, so its hard to argue on the point of stuttering. If tweaking the Toolkit fails I will try your way. Thanks!

Hi Diego999, some interesting approach where I have to dive in I guess. Did you manually modify the FFR area in OXRTK or edit the QVFR config file? I´ve done a couple of hours of testing today and got a little wiser by now, but if you can share your settings it would definitly be helpful, and not only for me I guess. The amount of "input" in this forum is so huge and depending on so many factors that someone easily can get lost.

Thank you and sorry for not mentioning my other specs, thought its enough to have them in my signature. Its a 5800x3d with 64GB DDR4 CL18 RAM, both not overclocked. DCS is running on a NVME. Very interesting, I will give the 60 Hz another try. Definitly would prefer a setting for all and deal with maybe not 100% squeezed out eye candy rather than the need to adjust setup every second flight. I The PD thing messed up my first test with 60Hz. As you say you do use the OXRTK only for Turbo Mode, is it correct that you don´t even use FFR? How comes that?

Good day Pilots, I´ve just upgraded from an RX 6900XT to a RTX 4090 and get a little lost in which way to go with my settings. I was tinkering with Quad View previously on AMD with good results but since the change to NVIDIA there are much more factors available now, like DLSS and DLAA and FFR via OXRTK. As I have missed the wave with DLSS & CO, I would really appreciate if someone could post a screen of the DCS, NVIDIA and/or OXRTK settings to have a good starting point. I have tried 60Hz mode but got some stuttering and can see some flickering in bright scenes, but I guess it might have been caused by some other setting mistakes. I fly 90% of the time rotor wings. Main questions: Go for 45fps + Repo, 60 Hz Mode or 90fps using some new technique (DLSS etc.)? Go for Quad View again or stay with OXRTK only? Upscaling? Yes / No / Which one? Sharpening - Which one? Antialising technique - Which one? PD adjustment in combination with FFR or QVFR? Heard that modifying the Quad View allows high center PD. Anyone tried this? DCS Settings which shall be definitly avoided in VR? I strangly got some heavy increase in brightness and needed to go to gamma correctiion 1,0 to have somewhat ok visibility. Help ! Thanks in advance, Uzi
