I’ll be testing the above this week
I have not. I’ve spent some time to try and replicate this. I tried with different raymarched settings. Also different view angles, weather and daytime settings. I could not replicate this. I suspected tessellation to play a role in this so I tried all combinations in Adrenalin, but it did not seem to have an effect.
Here are some screenshots:
Your RdrThread still seems a bit high. Have you tried with Mayhem6633’s suggestions on voltage, Buildings, Trees, and Grass/Bushes?
Buildings, trees at high or medium, I think, will check later. Grass is off. Still at 20% road traffic and using 22.11.2 drivers(VD recommends those).
Will try voltage and updating drivers later
What’s a good value for RdrThread?
I am content with render threads below 15 ms, but like it more below 10ms. Always try to put the most load on the Rdrthread instead of Mainthread (be GPU limited)
Nosing around the forums I found an old post which mentions some settings that influence Mainthread and or RdrThread. This will help tune it:
Just checked my voltage and max I can put is 1150.
Will take a look at that thread, thanks. I tried changing several settings including lowering resolution but I can’t get off that 26ms…
Ok, yesterday since my max voltage is 1150, I left it alone.
Upgraded to the latest AMD drivers.
Managed to get RdrThread to 10-12ms, I had to restart VD/SteamVR several times while the sim was already running and one of those times it lowered and was GPU limited(there’s something going on with VD/SteamVR).
Well I thought it would be great but turns out that led to having some kind of micro stutter of sorts. Where the objects are passing by but go back and then forward in a split second and then repeat that 1-2 seconds later. Tried many settings but couldn’t remove that behaviour.
Next sim start and I was back to RdrThread 26ms and all smooth without any rubberband or lockups…
Don’t know what to say honestly
I’d say if it’s smooth and without rubber banding fly and enjoy. Sometimes we get lost in constant tweaking and forget to fly and enjoy.

That’s true. It would be good to find out why thing are the way they behave but it’s good as it is. Thanks for your help.
Do you think messing with PBO will make any difference, here we go messing again 
I know where you’re coming from as I’m a constant tweaker and try get reason and sense behind things. Sharing experiences is important to create insight and understanding.
PBO tuning will allow your CPU to run at higher clock speeds for longer due to running a bit cooler. Let’s apply it to your system and ask the following questions:
Does your CPU run excessively hot and thermal throttle often?
If yes, it might be an incentive to play with PBO. (of course there are other benefits of having your components run as cool as possible)
MainThread or RdrThread limited?
If you had trouble shifting your system from MainThread limited to RdrThread limited, then use PBO to squeeze the last bit out of your processor.
Some things to double check;
Make sure you’ve got the latest bios installed for you motherbord. Most recent AM4 motherbord updates had specific optimization’s for the 58003XD
Where can I check temps and if throttled?
Limited by RdrThread.
I think I have one update availale for my ASUS X570 Pro Wifi. Will check later
HWInfo is a good one with lots of information. Alternative and also good HWmonitor
The 58003XD’s Max. Operating Temperature (Tjmax) = 90°C (Core)(https://www.amd.com/en/products/cpu/amd-ryzen-7-5800x3d#product-specs)
the processor will throttle aggressively after 90°C (Don’t mistake core temp for hotspot/junction temp)
Indeed, so that would not be a reason to tune PBO
Thanks, I’ll do the MB update and monitor the temps
