I use 83% even for clear weather. It's simple: at your view distance, fullhd would probably still do the job. Similar to my old setup. It was fine but a bit muddy when reading texts.Funnily when racing in the heavy rain, I can set my 3440 x 1440 to 70% resolution and get 20 fps more without really noticing any meaningful reduction in graphics quality. unfortunately this does not apply to clear weather.
Have I become delusional
May be I was misinformed then. From what I've read it does assign higher ratio to specific core, not randomly based on core load like TurboBoost.Yeah, it doesn't work like that. On Ryzen2, it was supposed to be a feature from the software Ryzen Master (the highest freq core was supposed to be always chosen). But as of today windows will chose any core to run @ you max speed, Ryzen or Intel.
So, if you have the time and patience, you will need to test each core individually with prime95, and apply the vcore of the worst performing core to all. To test each core individually with prime95 or lock AC thread to a specific core, just use windows affinity in task manager.
Per Core: Allows ratios to be applied to each core independently. In this scenario, when non-threaded applications are run, they can be assigned to cores that are running at a higher frequency to improve performance. However, current versions of the Windows operating system are configured to balance loads across all available cores, which results in all available cores reverting to the same ratio as the slowest core when faced with a workload. The workaround is to assign processor affinity for non-threaded workloads manually via the Windows Task Manager.
We recommend using the Sync All Cores setting in association with the AVX Instruction Core ratio Negative Offset setting, or with the ASUS CPU overclocking temperature control features to get the best performance from the Kaby Lake architecture.

Do you use process lasso to save your CPU affinity or there is another way to do it ?

And this post with quote from ASUS OC Guide seems to confirm that. Again, I could be wrong.

Yep, due to the swapping HT gives a bit more headroom. It's just logical like you said.I'm not sure how feasible it is in Intel land to bind processes to cores due to the task scheduler in windows and how intel cpu's behave.
I've seen some very weird behavior with core hopping/swapping of workloads which would give me pause of binding workloads. You'd really want to test this out per game extensively and not just do a set and forget.
I also can't notice any notable performance gain in VR performance in AC/iracing by having a 5.0ghz vs 5.2ghz outside of the 9900k heating up my house of course. Funny enough, enabling HT actually reduced my fps dips which again goes back to the way intel/win10 handle scheduling. If I had to guess the HT comes in when a particular load gets overloaded and the process decides it's faster to use a HT thread then split the the workload onto a diff physical core.
I have all energy savings disabled so it's a not a core parking issue.
You should monitor your clock speeds during the single thread part of the test and then check if locking them all at 4.6 GHz for example and see if you get a better result.Just got a 9th gen 9600k and overclocked it to 4ghz base clock and 4.8ghz turbo per core, this is what I'm getting with passmark.
