Ryzen 9 5950x Optimization for DCS VR - Ryzen Master

[Byzantine_SK]

Looking for some input and well-versed knowledge here. My understanding is limited at best… Anyway…

Would using the “game mode” on Ryzen master create any tangible benefit in sim performance? (Limits to 8 cores from 16 and allows for CPU optimization by focusing on smaller subset of cores?) 

PC Specs:

Windows 11
4090 FE
128 gb ram 
Ryzen 5950 x
ASUS Darkhero VIII
Reverb G2

DCS settings:

Running OB Multi Thread
MSAA x2
No up scaling 
All settings high expect view distance - medium 
Motion Reprojection on - unlocked 
FPS 45 fps to 30 fps.

Low level flight with Apache can be jittery - therefore, this request for advice!

5900x, 5800x, and 5800x3d user here.

I haven't had much success using Ryzen Master. I would recommend undervolting via your BIOS.

I also got a lot better performance by going to the 5800x3d and running DCS in MT.

@FETUS
if you compare 5900x vs. 5800X3D would you prefer the X3D?
Is it really the better choice for DCS (MT) ?

Considering only DCS and nothing else, the X3D is without any doubt the better suited CPU.

I tested both back to back on the same system, and the 3D performed ~20% better. However you are still GPU limited most of the time still.

On the other topic, once you enabled the XMP profile for your ram, you can only gain very very little with a lot of tinkering in the bios (or Ryzen Master). I wouldn’t bother, unless overclocking in itself gives you joy.

What render resolution are you using for the G2? Try to reduce the render resolution.

5800x3d I think it is the better choice for MT, hands down

I'm using the 5800x3d with a 4090. The G2 has been a workhorse for me in VR for the past couple years. 

You will definitely notice a lot more smoother VR experience with the X3D. If not already, try running in Open XR,  as well. If you're running motion reprojection ON and getting 30-45 FPS, I assume with it OFF you're getting high 70s? I had a better experience running Open XR Toolkit and in Turbo Mode then capping the FPS. 

I was looking to upgrade at one point to Ryzen 7800x3d but the difference in high res gaming is not much different in FPS than 5800x3d. 1080p is a different story if that's your thing.

I run my 5900X in stock power settings ( 200A max iirc ) but have set the Curve Editor to -26 All Cores, which is undervolting the cores per se with a -26 value if you are new to tuning 5000 series AMD chips.

I have pumped immense Ampere and heat through this CPU, cores up to 5.15GHz but in the end, it all was slower than this simple setting. Enable XMP, edit your Curve to minus 20 or lower

and call it a day.

*You have to spend some time to find the value that your CPU can work with, a too low value, max is -30 will almost certainly not feed enough volts and cause instability. Start with -25, most can run this, and see if it runs stable. If it does, you can try -26.....  Once you have found the lowest it can go stable you will likely see higher sustained boost speed.

 

If that fixes your DCS Apache issue, I highly doubt it tbh. But a better (less volts, less heat, higher speeds ) running CPU is a good thing, nonetheless.

 

edit*: This is all done in Bios, you do not need Ryzen Master but you could, I just dont like that GUI and how it handles things, I prefer Bios.
