Ok, then are you sure the rockets firing interval is correct? Right now it takes good several seconds to empty each pod, so if you aim and start firing in a dive at optimal parameters, the pods will still be firing while you're already pulling up and evading. Maybe it's 40ms instead of 400ms between rockets, something along these lines.

It's not placebo, just different terrain shadows settings, one has been fixed, the other (flat) was not.

The rockets in ripple mode will continue to fire for several seconds until the pod is empty, even after the weapon button on the stick is released.

The performance with terrain object shadows set to OFF is where it used to be in 2.7. The game looks worse, but at least it's playable. I hope it won't take long for ED to also fix flat shadows, it isn't the first time they were broken.

FLAT shadows were never superimposed over aircraft, that was an issue when objects shadows were set to OFF. Please re-read the first post. In the current DCS version both options look the same up close, but when set to FLAT, the shadows disappear at closer distance. So it's not just a mismatch in names in the menu, something is broken in the implementation.

The "Flat" terrain objects shadows are still broken in today's patch (DCS 2.8.0.32235.1). The performance drop with flat shadows is the same as shown in the first post in this thread. Setting the shadows to OFF returns performance roughly to the level of DCS 2.7. Except without objects shadows on the ground.

Only partially. OFF option has been fixed. You can turn off terrain objects shadows completely and get back the lost FPS. At a cost of no shadows on the ground. FLAT option is still broken as described in the first post, and still a massive performance hog.

What shadows settings do you use? Because these are "default" aka highest quality terrain object shadows. These work as expected, but most people in vr use flat or off.

You have the same shadows bug that everyone else. Note that the shadows in your 2.8 screenshots are smoother, while the 2.7 shadows are jagged. You've also lost the shadows under distant vehicles. The weird shadow glitches mostly appear at certain angles with terrain object shadows set to OFF, and you seem to have them set to FLAT? Posting 80 fps screenshot when your fps is locked to 80 in both cases is completely meaningless.

25% drop in cpu performance is larger than what we gained in the last three cpu generations from Intel and AMD. In other words, we would need several years of hardware development to close the gap that ED manged to introduce with a single patch. I hope it's just the bugged shadows that cause current performance issues.

Even on the thumbnail you can see 10% increase in gpu frame times, cpu frame times went up from 10.5 to 13 (more than 25٪) and his fps dropped by 8 or 15, depending on if you look at momentary or average fps. How's that an insignificant drop?

Added MB-339 from India Foxtrot.

It's only on the openbeta branch.

Here are my numbers on 2.8 https://forum.dcs.world/topic/311178-large-performance-drop-in-vr-after-updating-to-28/#comment-5074255 That's even more than 20% drop in the spot I compared.

This is Hornet Ready on the ramp instant action mission in 2.8, with RTX4090, Ryzen 5800X3D and Reverb G2. This is the same spot in 2.7 I made a week ago an posted on the forums, using the same hardware and settings: Compared to 2.7, the GPU frametime went up by roughly 10%. CPU frametime went up by roughly 30%. Yay. Notice the different look of shadows in 2.8. In 2.7 I used terrain object shadows set to "flat". Terrain object shadows options "flat" and "off" do not work correctly in 2.8, which may be the reason for the performance impact. See: https://forum.dcs.world/topic/311147-strange-behaviour-of-shadows-on-28/#comment-5074052

No difference.

The broken terrain shadows may be the reason for noticeably worse performance in VR. It's like the default "smooth" terrain object shadows can never be turned off unless you turn off the shadows completely using the option in the left column in the settings menu.

Unfortunately that's the way it is. For example, the guy you've linked previously uploaded an RTX4090 "test" on 11th Oct. That's the day when press embargo has been lifted, but the cards were not yet available to buy, and more importantly, the drivers which worked with 4090 were not yet available for download. Only the selected reviewers received them earlier. What are the chances nvidia would send a kit to this random guy? Not very high. Yes, they give cards to smaller reviewers and various influencers as part of marketing campaign, but those people are usually expected to show the card on a video, talk about it, etc. You know, do some marketing work or at least make an actual review and not just drop a bunch of numbers on the screen in total silence.

Comparison videos from small channels that look like this one you've posted, are usually fake.

Small YT channels with zero commentary and gazillion hardware comparisons never showing the actual hardware tested, are not necessarily the best source of information. Most of them are simple scams showing "emulated" results.

I wouldn't call a difference above 30% "a slight lead". The gap in 1% lows is even higher, although that measurement is typically not super accurate. Raptor Lake is also loosing to X3D in racing simulators like F1 2021 or Assetto Corsa. https://www.tomshardware.com/news/intel-core-i9-13900k-core-i5-13600k-cpu-review

Similar to Ismael's, except I got 5800X3D and Reverb G2, he has 5950x and Varjo.

Your CPU frametimes look really high even on low settings. I wonder if this is Varjo overhead, recording software inssue, or just 5800x3d doing its magic on my system. Do you have a full track for this benchmark? Because for me, the mission looks like this: Compared to:

It doesn't help much if the reprojection itself is of lower quality, with more artifacts showing. And the reprojection preemptively drops to 30 fps in places where it still maintains 45 on SVR. Anyway, I don't want this thread to turn into another SVR into OXR debate. I simply checked both and currently I can't tell a clear winner in terms of performance.

I may not be the right person to ask, I never saw any real gains with OXR on my system.
