The 2.9 hotfix boosted my VR performance quite a bit. With SSS on I’m now able to bump terrain shadows up to Flat. In dense forest and cities I’m capped at 36fps, going up in the 40s on the Supercarrier deck in the Tomcat which is super smooth compared to before.

I have been using MSI Tomahawk X670E +7800x3D platform with AMD Expo memory without problems, apart from long BIOS 30s memory check in the boot. Your mileage may vary.
But I would agree it is a bit immature platform. New bios versions are coming out frequently.

Thanks for that - hadn’t found that info in my review checks on AM5.
I used the CPU core parking app yesterday, but I’m not completely sure I needed it. Will see how things run later today.
I really wish there was a concise and understandable guide to the various settings and tweaks for DCS World. Even when I read the explanations given by ED about new possibilities I’m often left scratching my head. I used to run a computer repair business in the early days - I’d be lost nowadays.
in the end if you dont do rendering or video editing etc, you don’t need 12 Cores 24 Threads.
No Game, no matter what they tell you needs more than 6 Cores.
That being Said,
For Gaming Only,
The 64 MB of Stacked Cache on a Single CCX is worth more than the 4 Extra Core/Threads running a mere 300Mhz Faster.
That 300 MHz is easily made up with decent cooling and PBOII.
Heat is about the same, your trading 2 CCXs for a Single CCX with a Stack of L3 Cache on it.
The 5600X3D if you can find it is another 100Mhz Slower, with only 6 Cores 12 Threads on a Single CCX w/ Stacked Cache, everything else is the same, including TDP.
I’d say stay away from the 5600X3D for 2 Reasons:
-
it was a MicroCenter exclusive, so resellers are either going to inflate the price, or scam you w/ a fake 5600X in a 5600X3D box (ebay, here’s looking at you, and it has already happened, someone bought one, put it in their rig and took their old 5600X and put it in the X3D Box and sold it on ebay, un beknowingist that the person that bought it was a tech person and quickly checked the laser etched CPU Heatspreader and Immediately raised it with ebay, who sided with the buyer for once.)
-
Warranty, it was a limited production size, clearly they simply took extra core failed Chips form the 5800X3D bin and disabled 2 cores and sent them out as 5600X3Ds. What are they gonna send you if you need a warranty replacement? Likely a 5600X thinking you wouldnt know the difference, another 5600X3d unlikely or a 5800X3D with Software locked cores. also unlikely.

Thanks for the info, @SkateZilla.
I’m contemplating an upgrade, but I think I’ll wait with getting a new setup.
I am considering if swapping the 5900X for a 5800X3D though. But I am not sure.
This is the current machinery
AMD Ryzen 9 5900X
Gainward Phantom RTX4090
G.Skill TridentZ Neo DDR4-3600 C16 QC 64GB
ASUS TUF GAMING X570-PRO (WI-FI)
Samsung 960 Pro 1TB M.2 SSD
WD Black SN850 2TB M.2 SSD
Nice rig.
I treated myself…
Hope I actually get to fly them. Don’t think I’ve done a single payware campaign in DCS and the first one I bought was Vergeev back in the Ka-50 days.
I have completed a couple of the included campaigns, though.

Get a 5800X3D, $300-350 USD~ Often on sale on 'zon and 'egg.
Paired with a Decent Cooler or AIO / Custom Loop, Burn it in, make sure it’s stable, Tweak Clocks, Enjoy 5-14% FPS Uplift.
Sell 5900X to re-coup some cost, ~ $200 USD Used, $75 USD Damaged.
Ride out AM4 for another 2 years, you won’t be bottlenecked with a X570,
I run a x470 Taichi Ultimate and Haven’t seen any bottlenecks yet.
Only thing I cant max out is NVMe drives as it’s still PCIe 3.0 in Primary and PCIe2 in secondary M.2.
I’ll ride the the SATA6 2.5" SSD wave until my next upgrade, 500 Mb/sec vs 1000mb/sec on the secondary m.2 not worth it, plus it disables the PCIe 4x Slot which I’m already using so.
Wait it out on AM4 for Ryzen 8K Series.

Can the 5800X3D be overclocked with PBO2 now? I can’t overclock mine, but I’m on a BIOS version from shortly after its release.
Did this change?
Otherwise, yeah @Troll , I’m with Skate on this one. The number of cores and GHz does not seem to make nearly as much difference in games as the 3D V-cache. 5800X3D is a lot faster than the 5900X in gaming benchmarks, about 20%.

depends on the mainboard and bios,
i know guys that undervolted their 5800X3D and overclocked them to 4 Ghz out of the box

Good news (and some bad news) with the 2.9 testing.
I just updated with the patch and did a quick couple of flights to replicate my tests yesterday.
This time I used my Index. usually the Pico does far better than Index, but now it has switched around. At 120Hz and 150% res, running MT.
Unfortunately with Index I can’t get a screenshot including fpsVR - not how it’s set up, anyway. I took a through-the lens shot with my phone and though a bit blurry it’s clear enough - as is the big improvement! (*this is the A-10C at Caucasus - Shooting Gallery mission)
CPU is nowhere near as hard worked, though still very busy, and the GPU was slumming it! Rock steady 61fps with an average 71fps. That shot was taken at the airbase, on the runway next to my wingman, everything running.
Also, I’m sure now that the core parking app did do something - yesterday core 6 was hammered to 100% continually during mission loading. Today it was cores 1 and 3 (or 4) and they didn’t get maxed out - high 90’s.
No jumping, solid cockpit, smooth action etc. Well pleased.
then I loaded up the A-4E at Akrotiri. Whilst the figures were marginally better and there was no cockpit movement or stuttering as I looked around, I couldn’t fly cos I’m not 100% on the start-up for it and it doesn’t have an autostart option.
So, better and stable, but wait, out.
I then tried to load a default C-101 mission in NTTR, but DCS loaded for a minute or so then went black and froze.
End of test. Overall, happy - well a lot happier than yesterday.
edit: Even the Caucasus scenery looked better - which is normal, I found, in all sims when comparing Index to Pico or Quest. Vegetation always looks better with Index.

I’ve got to say, the trials and tribulations everyone is having with VR definitely reinforces the feeling that I am glad I’m not messing with it. I updated to 2.9, and everything runs perfectly fine in pancake no hiccups or weirdness. Getting 80+fps on my 2070 with the sliders largely to the right. I’ll continue to hold off on VR until it’s as plug and play as a USB mouse I think.

That’s valid.
Using my HP Reverb G2, I haven’t bothered with VR optimizations and tools in a while now. Years back, I switched to OpenXR but it seems that is the default now. When I updated to 2.9, I enabled DLSS and added a bit of sharpening. I like it, best performance/visuals exchange rate I’ve seen.
Looking forward to flying with Screen-Space Shadows only, no more expensive 3D shadows rendering should allow me to either bump the clouds to High or see 90fps. Maybe both. Been perfectly happy at 45/60 fps with Standard clouds so far.

When I think of the problem I’m currently having with my non tracking Varjo Aero headset, I have to admit I totally agree with you. While it’s quite nice and immersive to see the virtual world through a headset, it seems to me a bit brittle.
DCS 2.9 however runs very nicely on my system in 2D, no complaints whatsoever there.

That is precisely why I’m hesitating to move to the AM5 platform for my next upgrade build. Interestingly, several content creators are pimping AM5 builds but I only came across one that mentioned the potential issues. It seems that if you are considering a build you must make certain that your RAM is AMD optimized.
That said, I will likely stick with AM4 and advise my son to do the same.

I’m not alone then. Maybe then I can do the PC shuffle; my new-est one will slide over and become my dev box, current dev box to server? Gonna need more wall sockets.
I am in the same boat. I might pick up a 4090 if the opportunity arises but other than that I will stick to my habit of skipping one or two generations of CPUs
I was planning on picking up a 7800X3D but cycling takes priority right now

Well, I finally have great FPS in VR on Marianas now, but the helo AI in 2.9 is apparently borked. I really really wanted to resume my Paradise Lost campaign, but no joy.
The AI refuses to take off, only lifts to a hover, and stays there, drifting all over the place.
Reflected is informed of the problem, but looks like its on ED.

That’s a great campaign. I’m sure that they’ll get it sorted. The last few missions are worth the wait.
