2K is one of those stupid marketing terms that came about because people think bigger numbers are better. It’s confusing because it might be 1080p or 1440p or can be other vertical resolutions. It’s best to ignore it and just look at the actual resolution.
4K monitors typically have a horizontal resolution of 3840 pixels and so if you say 1920 can’t be 2K because it is under 2000 pixels then most of you are not running 4K either.
I will say that the 7800X3D is not as plug and play as most CPUs, you need to do some bios tinkering, at least that’s how I find my 670-E combination, some say the older 650 series is easier?
Hi, using my 7800X3D for 5 month now. I’m a VR pilot (HP G2, Quest 3 now). The only thing what I did, was a little bit undervolting :). The boost runs up to 5050 MhZ on all cores, the workload reached max. 85% on cores (primary on core 01). Installed a 7800 XT, tested a 7900 XTX also, but this CPU works on a solid workload, in all situations. Max. temp 81 degrees (watercooled).
I had to load X3D algorithms, enable EXPO, and UCLK 1/1, figure out which ECO mode was what and three bios updates to finally include rapid training … that’s off the top of my head.
Maybe my mainboard is more the culprit (Asus could be) and I’m not saying it was insurmountable, just more fiddly than I’m used to with a CPU install.
Oh and for price watchers AMD announces new APUs Jan 8th, rumor is in your face affordable performance from the low end
Yes, I’ve spent quite a lot of my time going between BIOS and in-sim settings.
Obviously, it works well for some people, but it was just a caution for the poster that it’s not necessarily a straight forward proposition to think (like I did) that I would get it running nicely on ultra with minimal tweaking in the sim settings. I’m still struggling to work out the quite significant temperature spikes I keep getting.
If I buy the R7 7800X3D I will probably not upgrade my gpu until next year as it is out of my budget. However if I buy the ryzen 5 7600X I will mostly buy a new RTX 4070 very soon.
At what resolution are you playing if I may ask? DX11 or 12?
Given the way this sim is, I’d lean on investing on the CPU rather than the GPU. I’ve got a RX 7900 XTX and I swear it’s just twiddling its thumbs. I’ve never even heard its fans other than when I went into Adrenaline and manually turned them to full RPM just to hear what they sounded like.
The CPU, at least for 2020, seems like the most important piece of the puzzle for sim performance.
1080 resolution set at 150 scaling.
Usually use DX11 but I’ve tried DX12 and whilst it was ok in most aspects, it seemed to struggle with panning using tobi head tracking.
Thanks. FWIW there are many reports on this forum of players enjoying a very fluid experience with the sim at ultra settings w/ 5800X3D/RX6800 in non VR mode. Your CPU is better.
Does the stutter only occur when using head tracking?
No. I can lock the head tracking and still get stutters. Sometimes, they are so brief they’re barely noticeable, other times it’s more akin to a freeze.
I think a lot depends on the whole setup, hardware/software etc., something that is very difficult, if not impossible under normal circumstances, to replicate between users and hence perhaps why some people seem to suffer with worse performance. As I alluded to earlier, it appears to be a bit of a lottery whether any given setup will perform as expected.
Yes. It appears to be the case.
When AM5 was released there was a long thread w/ someone who ordered a brand new, very powerful computer, with a 7950X3D/4090 combo, high end MB and plenty of RAM, with performance issues.
It turned out the computer shipped with a messy OS installation:
a fresh Windows install solved it.
I had a similar experience. The company I bought the PC from didn’t set it up properly (amongst other things, including a very old BIOS and an undocumented change in water cooler) and I spent ages troubleshooting that. Ended up reinstalling windows on top of everything else.
Anyway, I posted in another thread earlier about how my flights this morning were perfect and silky smooth, I was extremely happy. This evening, back to normal with low FPS and stutters, all with the exact same parameters. I feel like giving up on the sim on days like today.
The potential is obviously there, but some elusive thing is stopping me from enjoying this PC and sim.
True it can be very frustrating when MSFS performance is not consistent.
I had an issue like that on one of my systems. Focusing on network optimizations helped. In a nutshell I was behind a VPN, and my MTU setting was not appropriate. What gave it away was some inconsistent browser behavior on some websites.
There are so many moving parts with this sim…
7800X3D is an outstanding CPU for MSFS.
RX6800 has plenty of RAM for DX12 and its raw performance is OK at 1080p, nowadays it’s a good option for budget minded simmers.
Yet the result may vary from one day to the next!
I’m about to buy/build a new PC from scratch. I’m leaning toward the 7950X3D because I’m expecting FS2024 to better utilize multiple threads. Is this sound reasoning? The 7950X3D is already a pretty great CPU, so I can’t really go too wrong, right?
Has the 7950X3D’s performance improved for FS2020 over the past few months compared to the initial release?
Thanks for any/all thoughts.
For gaming the 7800x3d is better.
Ryzen 7 CPUs come with 8 cores per chiplet. The 7800 has only 1 chiplet and 8 cores, while the 7950 has 2 chiplet and 16 cores. The 7950 will be more highly binned than the 7800, but because the cores are spread over 2 chiplets, the shared cache system creates issues. On the 7950, if a process that was ran on core 1 moves to core 13, then all the information has to go back through the CCX to get to the other chiplet. This causes stutters and frame drops.
I should point out that only one of the chiplet is an x3d variant on the 7950. So you are not getting double the X3d performance of the 7800x3d. AMD said this did very little for performance, which is why they do not sell it that way. One chiplet is an X3d variant identical to the 7800x3d. The second Chiplet is a standard 7950 variant.
The 7800 only has one chiplet so can never have this issue of having to transfer information across the CCX. AFAIK there are no games utilizing more than 8 cores. I am sure someone will correct me if this is wrong.
AMD has been trying to solve this since the issue was spotted shortly after Ryzen 7 released. AFAIK this issue still persists.
This is the first google link I found. There may be better explanations out there. AMD may also have a fix for this around the corner. I highly doubt this will be an issue with the next gen CPUs.
EDIT: I should add we do not know how MSFS2024 is going to run on the 7800x3d V’s the 7950X3d. Asobo may have introduced their own fixes for the problem by coding in their own scheduling.
I’d ask all that in the 7950 thread.
We have not seen 2024 yet.
What is supposed to happen is some of the tasks that are now stuck in the main thread won’t, i.e. instead the game will make better use of multi-threading.
IMHO, MSFS2024 will perform even better with 7800X3D.
7950X3D is a great CPU, but it is not required for MSFS itself.
Even when using companion apps.
2024 will not make full use of 32 threads across two CCDs. 16 threads in one CCX is plenty.
If the PC is used for video editing, etc… it’s a different story. This is where the higher end CPU will truly shine.
I already bought a 7950X3D a few hours ago along with a 4090. I think I’ll be happy with it regardless! Hoping for the best with FS2024!
