That's crazy that it can be triggered by camera angle, I hadn't even thought of that !?!
For what it's worth I replaced my 5800X with a 5800X3D today (en fait, hier soir et ce matin) and the exact same problem persists. Just that now the X3D gets me about 10FPS extra in all situations, but it doesn't remove the end-of-stage GPU performance drop bug.
I don't think this is a memory capacity or bandwidth issue, or at least it seems unlikely.
For CPU I have 2 x 16GB 3800Mhz CL14 B-Die (G.SKILL)
For GPU the 7900XTX has 24Gb of ram which I run stable well over the already impressive spec, ie: 2774Mhz (stock is 2500 Mhz).
I've done a lot of "volunteer" troubleshooting for EA (old F1 series 99-02) and CM (multiple series for well over a decade), but can't remember too many words of thanks. Perhaps back in the day a couple of CM folk would get on the forums (or twitter) and engage, but that has been dead for several years now. I don't expect it, all I want at the end of the day is for them to fix the bugs that negatively impact my gameplay experience. I'm rarely one of those people demanding new content or features, but I do insist that what is sold to me work to a generally acceptable level.
I'm convinced we're chasing a ghost here. There is something in the code that is causing this strange issue, and probably little to nothing we can do as end users to properly identify it or adequately mitigate it.
I've made my analysis so CM have something to refer to, should they care to, in order to squash this bug. I've been around long enough to know not to hold my breathe.
I don't think I can provide much more, but here's the result from Radeon GPU profiler:
This is not the best as I had to run vulkan from amdgpu-pro which is way slower than RADV, but still shows what's needed. With RADV the GPU idle is more like 40%.
Even better, I managed to capture a cpu bottleneck while running at 160+ fps with almost all high settings and bumper cam:
The game never seem to use 4+ GB of ram. It's almost like it's limiting itself to that value. The highest I've seen PMEM go is 3.9 GB

At 4K I get around 6Gb +. I don't think that is particularly abnormal for this type of game.

I faced the same problem. Graphics settings 3840 x 2160 maximum quality! You start the race and in some places the game stumbles and twitches, then moves smoothly, then twitches again.
Does anyone have a solution to the problem?

Yes!
Stop trying to run 4K at maximum settings with a 3080Ti and an ageing CPU.
Also turn car reflections to Ultra Low, see how you go.
you don't need to tell me what to run in 4K. I have all modern applications in maximum settings in 4K. WRC EA in ultra 4K settings goes very smoothly, and the next launch goes in spurts, then the next time smoothly again. That's the only problem! The WRC EA 2023 game has bugs! All other games and professional applications on my CPU work calmly and stably! This is your outdated processor,! You don't know what to say in essence, pass by!
Try my suggestion or not, up to you.
I don't have stuttering problems with a 5800X3D and 7900XTX, when I adjust graphics settings accordingly.
Your hardware can't run this game smoothly at 4K Ultra, I don't care what you can do in other games and applications - completely irrelevant.
Yes WRC 2023 has bugs, that's not the question you asked. You asked "Does anyone have a solution to the problem?" and I gave you one.

No, dude, this is just very important! Because you're lying and misleading me and others! My equipment is on the recommended list. Check out the official requirements for the game. They specify the RECOMMENDED processor - Core i5. And not even an i7. I have a Core i9. This is one of the best processors and it is on the list of recommended ones in excess. The recommended graphics card is RTX 2070. I have an RTX 3080 Ti. Both components are in excess! This AMD hardware of yours doesn't matter at all! Pass by, child!
