AMD 5800X3D, the new King for flight simulators?

Just had a little test flight in the F-14. Everything fine and smooth (OB version)

Hi,

I have this CPU, although on a Dell motherboard (Alienware prebuilt). I'm getting lots of stuttering within the cockpit, seems like the more complicated the plane, the more stuttering (F14 lots vs P51D none). 

FPSVR monitoring tells me that normally CPU frametime is around 12-14 ms, while around the carrier it gets up to 30 ms.

I've tried all kinds of optimizations to no avail. My best bet is still the CPU causing the stuttering (my GPU frametime is under 10 ms, GPu being always green, while CPU always having orange spikes, and completely red around the carrier).

Anyone with similar issues? I'm running DCS stable version.

Thanks

If you have textures (not terrain textures) to high, try bumping them down to medium. I found my issue was high textures in the Apache and other newer / high detailed modules were maxing out my VRAM, even with 16GB, and overflowing into my system RAM (also 32GB). Both were maxing out!

Were you in VR or flatscreen? My experience is specifically in VR

[Lange_666]

Both.
2D: Overall high settings (with shadows off since 2.8), clouds to Ultra (even at Ultra settings, clouds in 2.8 don't look that good, specially around the edges), screens to 1024, MSAA x4, Anisotropic x16.
VR: Medium to low, screens to 1024 for clarity, main reason for going lower is that i want to run with MSAA to x4 and Anisotropic to x16 to counter the high shimmering if ran without, same goes for clouds, set to Ultra since 2.8, otherwise they look ugly, certainly on the edges, compared to 2.7, used to be on standard with 2.7.

On simple missions i can go quite a bit higher on settings but i keep them that way for more complex multiplayer missions where there is (a lot) more demand.
I also cap the FPS to smooth everything out:
- 60 in 2D, because i like to keep the FPS as steady as possible, if FPS fluctuates to much, TrackIR doesn't play nice on fast moving terrain. 120 would be nice to but i can't hold that across the board so the cap is 60. If TrackIR wouldn't be so picky on it's own pull rate, i would let the FPS do it's thing.
- 40 in VR, (Rift-S = 80Hz) but here plays the same as with TrackIR, jumping FPS makes everything stutter. So i just ASW at 40Hz giving a steady 40FPS which makes it smooth, no stuttering.

Never found fluctuating FPS a good thing, it's always visible when they jump around and i don't really care for low frametimes, not needed. The more steady they are, the smoother.

I’ve just run Cinebench and the CPU is working as expected. However, in game in VR I seem to get more stuttering when CPU frametimes struggle. Unfortunately in the F14 this is constant. Other planes the experience is better. 
i wonder if there is any other way to unlock more performance on the CPU in game. It’s running at only around 62 degrees, while frametimes can be up to 30 Ms at an airfield in the F14

That doesn't sound right, typically at an airfield I'll have around 10-12ms, admittedly not in the F14 though.

Have you properly tuned the system as per the guides at VR4DCS? Have you killed the winwing exports as they've been known to eat CPU cycles.

[Lange_666]

Also, do a test run with everything off, hardware and software (and remove all exports and hooks, not only winwing), that is not DCS related (you also run a motion sim if i'm correct), run even without controllers (if needed, unhook them), just use the keyboard (make sure nothing runs in the background) and add your stuff bit by bit. Something is clogging up.

Edmuss, thanks a lot! You've got it. I disabled the winwing exports in Simappro and that made all the difference. 

Just had my first landing in the F14 where flying over the ship it wasn't stuttering. The hook switch didn't stutter as I employed it. Feels like a complete new game. Even on the carrier I don't get the stuttering. I might need to replay Zone 5 campaign now xD

That one click in the software made all the difference. Now CPU times are around 8-10 ms (from 15-20 ms). It's in the green for the first time. FPS is stable at 45.

It should probably come as part of the throttle package information as other people might be struggling with the same issue. Might email Winwing about it.

Thanks again, happy new year!

No way should joystick software have that kind of affect on gameplay.

They should correct this.

Awesome that it was such a simple fix and you've removed the bottleneck

It's been a known issue for a long time,  about the winwing exports. I have no idea if the issue is with winwing or DCS but it does catch people out.

Did a little digging. Asus has not released the new bios for the Crosshair VIII mobos yet. Currently there is a beta version that includes the return of the curve optimizer, beta version 4303. Hopefully it will be officially released soon.

Looks like Asus has finally dropped a bios update with version 4304.

And yes it does have the curve optimizer.

Gamer Nexus has the review of 7950x3D and mention something regarding new driver and optimizer. But I am not sure if it also for 5800x3D.

[noxyd]

can't wait for the feedback of a DCS VR player using a 7000X3D now !

I think the 'optimizer' is meant (also in conjunction with xbox-app) to detect if the running app is a game, in which it will park the non-Vcached CCD or if its a non-game-app, where it will use both CCDs.

I dont think this will have relevance for current 5800x3D-owners.

Yep, it's correct

I'm wondering if multithreading changes this discussion or if the cache still makes the difference. 

[Sandman1330]

I’m finding very minimal improvement after MT. I suspect the stronger CPU meant I was closer to GPU bottlenecking even before MT. Now I’m hard GPU bottlenecked.

It DOES seem to help a fair bit more in busy missions though, where even the X3D struggled.

I finding really great results with my 5800x3D, but I am on a 4090.

Did you try this?

I’ve used process lasso in the past, but not recently. Maybe I’ll give it another try.
