Performance Drop at end of Stage
Performance and GPU usage drop significantly around the last sector of every stage.

A lot of info about that in this thread: https://answers.ea.com/t5/Technical-Issues/Old-Report-Low-GPU-Usage-and-Framerate-WRC-DLSS-no-change/td-p/13150831
For some reason, it was closed, but this was never fixed.
yes still following this, Do you also have examples of how far your FPS drops down? On your system and mine I believe it should still be able to stay reasonable(forgetting VR mode performance for now), say 50-60FPS dependant on graphics settings.
Out of curiosity which motherboard and PCI-E slot revision are you running at?
I'm on a 5800X3D with Radeon RX 6800 but with a B450 Motherboard that restricts my PCIx16v4.0 slot to v3.0.
Seeing as the issue is still appearing and for people running more powerful GPU's than me my next brute force attempt to workaround it is probably going to be -build a system based on the recently released Ryzen 7 9800X3D CPU, this may also allow me to see if PCI-E slot bandwidth has an effect(doubtful).

I don't think there's any getting around these specific end of stage frame drops with brute force on better hardware. The engine straight up chokes in these moments, and the fastest hardware/cpu/gpu/ram/storage in the world can't do anything about it.

Game goes from 115 FPS and 6% GPU idle to 75 FPS and 35% GPU idle. I think I saw someone mentioning that 9800X3D handles about 100 fps when the performance drop kicks in.Some event graphs. "Good" frame:
"Bad" frame:
You can see massive idle times in the gpu events. There are no barriers there, pure gpu idle waiting for tasks. What's concerning that there's still some idle time even in the "unaffected" frame.
Call comparison (the car has only moved about 10 meters here):I keep checking this forum to see if this problem has been resolved. I refunded due to this problem, otherwise I quite enjoyed my almost 2 hours with WRC. Extremely disappointed that it still hasn't been fixed.
It is really annoying that this issue seemingly won't be fixed by EA / Codemasters. I mean, it is absolutely clear that there is a massive issue with performance drops towards the end of EVERY stage! How can this not be solved by now? It has been 1 1/2 years and the issue is still there and noone seems to care about it. Is anyone from EA actually reading this and trying to forward it to the development team?
