Low GPU Utilization, is there something wrong?

[Dan]

Hi, I realized the game has very low GPU usage on my RTX 4080 16gb, something like 30-45% GPU Usage and 20% CPU Usage (10900k), the Framerate is around 110 but can easily dip to 50-70 in scenes in Chapter 5 with the rain and all (the GPU is around 30% at this moment, even the fans are slowing down). Somehow all stats show the rig is underused, is there a setting that is causing that somehow? I tried with and without GSYNC, same result. I even tried my older 3070, the results are very similar but lower fps and a bit more usage.

The remake uses only one thread properly from your CPU (hence your frames won't be super high unless you own a top tier CPU) and chapter 5 is the most CPU intensive chapter in the entire game (village comeback to be exact), which means that whether you set the lowest or the highest settings, it will not matter because the settings only affect your GPU and in this case the GPU has nothing to do with poor performance.

The only real solution is to either: significantly overclock your CPU (not a good idea unless you know what're you're doing) or just getting used to it.

Depending on your motherboard, overclocking is super easy these days. Used to if you didn't know what you're doing your cpu would literally burn up but now there are so many fail safes overclocking is nothing.

Cpu bottleneck no doubt. I am running a 7700x and fortunately have not had this issue in the least. But I know exactly what it feels like and it's not fun seeing that gpu utilization so low.

Did you try tweaking the setttings? Definitely turn ray traycing off as it impacts the cpu hard.

If it is a CPU bottleneck, then why is its usage at 20%??

20% is probably the overall usage. If you want to see if it's bottlenecking you have to look at the per core usage and one or 2 threads are probably maxing.

You are right thank you, I put my overclocked settings and the boost is significant. Is that normal behavior for the game though? One thread is not good...

This, exactly what is the problem with usage I had

Its the chapter with the Heavy Rain after finding Ashley, your rig is not the issue.

I'm currently doing some testing and I'm in line with you here, something's not behaving right in this chapter. Although I saw a difference with the overclock, that single thread is still far from 100% still. It's around 65%

what resolution are you playing at..i have a similiar pc albeit a 10850k @ 5.5 ghz. 1440p and up helps alleviate cpu bottleneck.

also turn off raytracing..its not well implemented in re4 and performance loss is not worth it for image quality.

Thanks, yes I was playing at 1440p with RT off. Still it's a very enjoyable experience but those numbers left me with questions about optimization

Unfortunately it is. On one hand it's impressive the game can run above 100 frames at times on my somewhat dated ryzen 3700x with just one thread (so you can say it's well-optimized), but on one hand the performance would also be much higher if capcom had optimized the engine for multihreading (so at the same time it's not so well-optimized)
