Poor performance and low GPU usage.
I have a i7-8086k, an RTX 4070, 32GB and the game installed on an NVMe Samsung 970. The GPU is not used at 100%, it always runs around 45~65% usage and there is not bottlenecking cuz the CPU Usage i...

CPU around 25-30% OVERALL doesn't mean that it is not bottlenecking your GPU. You have to look at utilization of the individual cores to check for a CPU bottleneck.
Doesn't mean the game should not be further optimized, it's just a common misconception to only look at overall CPU utilization instead of core utilization when looking for a CPU bottleneck.
@RaceOwl87 Hello, you're right, but I know what I'm talking about, I've been assembling gaming PCs for 25 years, I even do projects for manufacturers and in this case each core does not exceed 30% of use. Plus, it's the only game that happens to me. I have much more demanding games, and my GPU works at 100% without problem. It seems that the optimization problem is in the reflection of the cars. When you lower it, the GPU increases its usage although it still does not reach 100%. It is not something isolated to me, it happens to many people even with RTX 4090 and a Ryzen 7800X3D or an i9-13900K. You can look at it in other forums. It's an optimization error. Thanks for your answer.
@AstramusThanks for clarifying! Just wanted to make sure because many people on the internet just don't understand bottlenecking at all. Good to hear that you are not one of them. 🙂
Do you get 100% GPU utilization in menus and pause screens though? That's what I'm getting. GPU usage only drops when I'm on a rally stage. Even in Rally School, I get 99% GPU usage, but never in a normal stage.
Definitely a serious bug that should be fixed asap.
5800X3D + 7900 XTX here btw.Hello, exactly the same thing happens to me as you. In menus the GPU reaches 100% perfectly (well, not always, but it is used much more) and obviously, in menus I even have 230FPS on some occasions. The drop in performance only happens to me in the stages. Only occasionally at some stage I get 100% for a couple of seconds but it fluctuates again. With the new patch the stuttering has improved, but unfortunately it remains the same. 32GB DDR4 3600MHz, i7-8086K @ 5GHz, the game installed in a Samsung NVMe 970 and my GPU is an RTX 4070.

5800X3D + 7900 XTX here btw.- @RaceOwl87 Hello, yesterday testing the WRC, by chance I discovered that it is indeed an optimization error. I tell you, yesterday I started playing Rally School and I realized, that in that part of the game, it stutters sometimes, but the GPU usage increases to 90~100% and the FPS increases to 110~155 while CPU cores remain between 30~55% usage. Everything works correctly in the Rally school (except the occasional micro stutters) So I can confirm that the failure is in the stages.
I can also confirm the low CPU and, particularly, the low GPU usage during stages. Despite the very demanding scenarios (e.g., Finland, where some stages range from 90 fps to 60 fps in just one corner), GPU usage never reaches 100%.
These numbers point to a problem with UE4 code optimization, since hardware resources are never fully utilized and, as a consequence, performance is severely compromised.
My PC specifications include a AMD 5600x, 32Gb of RAM and AMD 6800XT (XFX Merc 918).
