I just use this to toggle core parking on/off. I no longer have stuttering but I don't think this was my cause of stuttering. I still keep the core parking off anyway.

I use this app. https://bitsum.com/parkcontrol/

Just tried this. It looks great.

You could try increasing the resolution. If you are using QVFR just try pushing this up high. I set the foveated region at the equivalent of 4600 pixels. As the region is only 0.25x0.25 it only has minimal impact and I hardly see any ghosting.

It depends on how much you want to spend. Probably the best deal at the moment is the Rx 9070xt if you can get one at MSRP. The performance is close to a 5070ti. The downside is no DLSS. If you would prefer a less expensive GPU then wait until the rx9060 and rtx5060 series are released. Or look into the used market. An rtx 4070 or rx 7800xt.

They look reasonable. How does it look in game for you and does it give you any performance boost? You can try getting the foveated region as narrow as you can cope with as this has a big impact. For example 0.2x0.2 = 4% of the total FOV. 0.3x0.3 = 9% and 0.4x0.4 = 16%. Yours is set to 0.35x0.35 which is 12.25%. I use 0.25x0.25 (6.25%) but I use a Quest Pro with eye tracking. Try 0.25x0.25 and you should see a noticable difference in performance. Reduce transition thickness to 0.1 (20%).

I would aim to upgrade your GPU at some point. It's probably worth waiting until the 50xx series hype and overpricing has settled down. If you can get something with a similar performance to a 4070 then you will see a big difference. For now try minimizing your settings. The ones you posted earlier in this thread are very high for your setup. Do everything you can to minimize VRAM use. Visibility range, textures and shadows are big VRAM hogs. You can also try the "Empty Hanger Mod". This reduces VRAM use. https://www.digitalcombatsimulator.com/en/files/3336353/ I would also advise using Quad Views Foveated Rendering in fixed mode. This will give you better performance.

I have experience with 4 GPUs in DCS and 3 VR headsets. I started with an Rx 6700 which is similar to a 3060ti but has 10Gb VRAM. My experience is that this GPU works ok with a rift s but anything else pushes it too far. When I got a Pico 4 I then upgraded to a 4070. Even a 4070 is pushed without QVFR. I used a Quest Pro with a 4070 for over a year and it's OK but still limited. The last few weeks I have tried a 5070ti and now a 5080. I'm not suggesting you pay for a new GPU but you need to manage expectations. With a 3060ti you will be OK with simple modules and well optimised maps. As long as your DCS settings are set quite low. Keep shadows low, visibility range to medium, DLSS performance, keep the details sliders low and use QVFR in fixed mode with a small foveated reagion. Anything else will seriously push your GPU tender time which will drop you below your headset refresh rate and cause frametime spikes.

I have done a comparison of more demanding track. This is a free flight of BF-109 low over Cairo. I did not use XRFrametools for the 5070ti test so I have had to use OXRTK so not every frame is captured. The mean GPU frame time is 9.1ms for the 5080 and 12.7 ms for the 5080. A 39% difference. All settings are as per the tests above.

VRAM appears to be less of an issue with 50xx series. I use VR and the max VRAM I have used so far is about 11.5-12Gb (F-4 take off from Marianas). Same for the 5070ti (which I had for about 10 days).

It looks like you have a network issue. The networking latency is high and your max Bitrate Is only 20 mbps. Is your PC connected to your router with an ethernet cable? Is your router close to your headset? As you already have a good cable that has passed the meta test, I would suggest using meta link. It works very well and is at least as good as VD. I mainly use meta link now. For me it is a more stable experience than VD at the moment. I can get 960 Mbps and the clarity is slightly better than VD (very subjective) and there is less latency when moving your head quickly.

I'm not sure. It would be worth looking at your performance using CPU-Z or similar.

Does anyone have a 9800x3d and a 4090 using a Quest Pro? I'm interested in comparing this with the 5070ti and 5080.

Yes. A 32% increase at stock speeds and a 28% increase when overclocked. Of course the overclock potential will vary between cards. Also, this is a single test. I need to compare the two in a more demanding situation.

I just tried the F-4 take off from Afghanistan in VR. About 11.5 Gb VRAM on the ground. Less in the air. Slightly off topic but the ground is very poorly optimised. If I look straight ahead I get 72 fps with GPU frametimes about 10 ms. Look left it increases to about 12 ms. Look right and it increases to about 20+ ms. I don't know what is going on but it creates some very weird fluctuations in FPS unless you keep your head very still.

I have been lucky enough this week to be able to compare the 5080 FE with the 5070ti (MSI Ventus x3 OC). Setup A 9800x3d with a x870 motherboard (Asus), 64Gb DDR5 RAM at 6000Mhz, a 2 Tb Lexar EQ790 NVME drive (game drive). The CPU has a liquid, three-fan cooler. When comparing the two cards all settings are the same. DCS settings are at the bottom. The cards were compared at stock clock speeds and with overclocking (MSI afterburner).

I used “XRFrameTools by Fred Emmott to capture single frames over a 1-minute period (4300 frames). XRFrameTools/README.md at main · fredemmott/XRFrameTools. Data recorded: CPU render time GPU render time VRAM use (current) FPS The results were extracted to a spreadsheet and used to calculate average values (plus min/max) and the number of missed frames (those that exceeded 13.9 ms; (1000/72 = 13.89 ms)). This is shown as the red dotted line in the charts. The charts represent the number of events occurring in 0.1 ms bins from 0 to 20 ms, displayed as a percentage of the total frames. What this shows is the distribution of frame times and the consistency across the track. Ideally, these should look tall and narrow to represent consistent frames times. Results The blue traces show the results for the 5070ti. Base clock (open). Overclocked (filled). The green traces show the results for the 5080. Base clock (open). Overclocked (filled). GPU render times were 2 to 2.6 ms faster (approx. 28-32%) for the 5080 vs the 5070ti. Overclocking for each card produced a 7-8% reduction in GPU render times, and a more consistent distribution (narrow and taller). The stock 5070ti was pushing the 13.9 ms boundary which could lead to missed frames and stutter.

There is a "tick box" at the bottom right of the VD headset menu which allows you to view stats in the game: "Show Performance Overlay".

I like the look of the eye tracking version. My main issue is that you need to buy base stations and controllers separately.

The bitrate is very low. Ideally you need 150mbps+. Could you please post a screen shot of the in game overlay? Try meta link. You should get a better experience than you are with VD at the moment. Download Oculus Tray Tool and then you can adjust settings such as the image scaling, control of ASW and cable bitrate. If you are lucky you should be able to get at least 500mbps, possibly the highest at 960mbps.

Meta link has worked fine for me with the 5070ti and the 5080 with the latest NVIDIA drivers. The meta link desktop app does not recognize the cards but just gives the message "your system does not meet the requirements". It still runs though.

There is a massive variation in CPU and GPU load in DCS. Up high with a limited number of planes, you can get away with lower specs. With more objects, newer planes and low down on poorly optimized maps (e.g. Marianas) even high end systems struggle. There are certain situations when GPU and CPU appear overloaded and it is not clear why. I have recently upgraded to a 9800x3d and even that is very stressed in some situations. I think it might be QVFR related when the GPU is maxed out. I am working on some VR benchmarks to look at this. Hopefully I will be able to post them soon.

I like what AMD are trying to do, but the recent increase in MSRP of the Rx 9070xt is a bit frustrating. Especially as it is very difficult to buy anything even at that new price. I am hoping that over the next few weeks the stock levels will make this card more accessible. They are certainly being more proactive than NVIDIA.

For VD you need a dedicated wifi 6 router connected to your PC by an Ethernet cable and close (2m) to your headset. Otherwise you are likely to have poor stability. The VD discord have information on the best routers. https://discord.gg/PPJrGY8U The other option is using meta link cable. You need a decent cable such as this one: https://amzn.eu/d/8PcVw87 A lot of people will tell you that VD is better. There are pros and cons with both, and I often switch between them. However I mostly use Oculus cable link. The other thing to try is Quad Views Foveated Rendering. This can be used without eye tracking and can give you a big performance boost. https://github.com/mbucchia/Quad-Views-Foveated

Welcome to VR. If you have persevered for 3 weeks then you now realise that VR can be a challenge. Don't give up. With your PC specs your fps is about where I would expect if you are at full resolution. Before going any further some more information would be useful. What are your VD and DCS settings? VD does not support usb connection, unless you have used some unofficial workaround. Could you share a screenshot of the VD in-SIM overlay?

Glad you like it. What are your system specs? I am thinking about benchmarking QVFR settings with different setups to help people with QP get optimal results.
