I think this blurb is meant to imply that individual members of the team have previous experience, not the company itself.

Aaand despite all the feedback posted in this thread for two months, the issue has been pushed to stable today. Are we allowed to be disgruntled now? They didn't even fix the flat shadows, just left the option broken as it is.

Turn off terrain objects shadows. "default" was always costly, the more units and objects in view. "Flat" is still broken in 2.8, and not flat at all. They look like "default". So far "off" is the only option that lets me play the game with performance comparable to 2.7. You can still crank the main Shadows option on the left to "high", so you get a nice cockpit and self shadowing on the aircraft, plus clouds and mountains shadows. "Terrain objects shadows" only controls shadows on the ground from buildings, trees and vehicles.

For a start, Flat Terrain Objects Shadows are still broken and cost much more FPS than they used to in 2.7. Although 'high' DCS preset is not using those IIRC.

As explained above, it's a problem of the framerate not matching refresh rate, and can only be completely solved by reprojection or running the headset at full refresh rate. Now that your PC can consistently make more than 45 fps, you can first try with reprojection on.

5800X3D heats up considerably due to the cache layer on top of the CPU itself. It's just the nature of the CPU, anything below 90C is fine, at or slightly below 90C is where you'll see throttling. Also the way it heats up is different than with 5900X. 5900X would report highest temperatures at light workloads (2-4 cores) when the voltage is highest. With all-cores workloads it will lower voltages, clocks, and stay relatively cool. 5800X3D on the other hand gets warmer the more cores you put to use.

Apart from the common performance issues in 2.8 unrelated to any particular module, I also find the Ka-50 to have worse performance than any other helo, including Apache and Mi-24. It is about 10% more taxing on the GPU, despite having much less detailed cockpit and no second crewmember station in the front.

You need to set terrain object shadows to something other than Off to see shadows under aircraft.

The one on the right. The left option I have on high I think.

Going full screen never gave me noticeable gains in DCS in VR, besides, both shots in my original post were made in windowed mode. 3 weeks and 2 patches later, flat shadows are still broken, and with them enabled, the performance is just as bad as I showed in the first post.

Yep. They changed something, because now flat shadows do not disappear at close proximity. But the flat shadows still look close to "default" option and they suck similar amount of performance (a lot). Nowhere near what we had in 2.7.

Can you change the tacan channel knobs clickspots to work with mousewheel instead of mouseclicks? Just like the VOR frequency knobs work right now. Scrolling is easier than clicking a dozen times to set the required channel.

I have a custom snapview saved under Num0, and using Ctrl-Num0 to switch between the snapview and default view works fine, until I switch to outide view, then it stops working. Normally you can switch between default view and snap view by pressing Ctrl-Num0 repeatedly, but after the following sequence it breaks. 1. Press Ctrl-Num0 to switch to snapview. 2. Press F2 to go outside 3. Press F1 to go back in the cockpit 4. Now you are back in the snapview 5. Press Ctrl-Num0 again. Now depending of if you are in VR or 2D, different things happen - if you're playing in VR nothing will change, you are stuck in the snapview - if you're playing in 2D, then the snapview will change but not to default view, but some other angle. Both behaviours are wrong. After pressing Ctrl-Num0 the view should go back to default cockpit angle. CockpitViewToggleBug.trk

Yes, the performance hit with 2.8 is not limited to VR. The thing is, from the data I showed in the first post, CPU frametimes went up by 30% while GPU frametimes went up by roughly 10% at the same settings. So for people who run DCS at GPU limit, they only saw about 10% drop with 2.8, while those limited by CPU saw 30% drop. On a monitor with 100+ FPS, that's not even perceivable without FPS counter. But in situations where DCS framerate is limited by CPU performance (like heavy missions or MP), a 30% drop becomes very noticeable. VR users are also more often dialled with the settings near the limit of their PCs, so any drop like that will kick them out of the "sweet spot".

Well, ED themselves already renamed this whole forum to DCS 2.8, and the newsletter last week proclaimed 2.8 was released, not even mentioning the beta anywhere. Seems a clear message to me. https://forum.dcs.world/topic/304804-official-news-2022/?do=findComment&comment=5073724 Anyway, the problem hasn't been fully resolved yet, let's hope it will be fixed before beta branch gets copied to stable.

Note that 5800X and 5800X3D are not the same CPUs. You want the latter.

The most cost effective option would be AMD 5800X3D (recently they had a price cut), a decent B550 AM4 motherboard, and keep the current DDR4 ram. With other platforms like the latest Intel or AMD AM5, you'll be spending almost twice the money for very little gains over 5800X3D.

Thanks. Looks useful. I've been playing the tutorial mission, so no way to adjust it there.

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.
