Lighting quality. Please read the topic.

[Constantine☦]

Lighting quality is not optimized in this game. The average lighting quality value has a big impact on the frame rate. When the camera angle is on a large light source, the CPU load of the video card strangely drops. It can reach 60-70-80-90-99%. As a result, this leads to a decrease in the frame rate. Look at the % loading of the video card below in the video. I don't speak English well, but if someone can bring everything to the developers, maybe they will fix it. The quality of lighting is all the more noticeable at games with the RT turned on.
Thank you for your attention. And I know perfectly well that the owners of the 4090 video card cannot fully enjoy the game with RT turned on at maximum settings.

Who will share thoughts? I think everyone is in the same situation?

not sure if its the lightning, you get always more fps in games when you look down the floor because there is simply not as much to render as when you look up.

[scoorh]

framerate drops because you are looking at larger portion of the scene with multiple dynamic lights where more models contribute to shadow mapping calculations (which nowadays should eat the most gpu resources)

why cpu load increases when facing away? probably unreal doing some loading/unloading or caching in the background or perhaps that fire particle emmiter is too heavy when upclose :>

Do you think this is normal? I think it's normal when the GPU CPU usage is stable at 90+%. There are clear optimization issues here. The video card must correctly handle the light source.

To sum it up, the stuttering is mostly fixed, but there is something severely wrong with CPU utilization. It's still under performing just as Digital Foundry reported. You will not get a prime experience playing the game as is.

You are an adequate person. Thank you for understanding me.

Buddy. Watch the video. The CPU load of the graphics card should be stable. Due to such a decrease in the loading of the video card, the frame rate in the game decreases.

[Constantine☦]

Or are you saying that my video card or the owner's 4090 video card can't handle the lighting quality on the U4+ engine?

[Constantine☦]

They fixed the stutter. But I hope for future patches that will fix the problems with the competent use of video card resources.

in my opinion yes but also no.. having in mind that this game was made with unreal engine 4 which was designed for old graphics api like directx11,

in many cases using dx12 decreases performance in old engines simply by sending inefficiently made gpu commands underutilizing gpu in the end

have they made this in ue5 it would work much much better imo

they can fix those issues only by tinkering with level data and engine settings

however having few places where my rx 6800 xt chokes on dx11 tells me that they didnt spent much time doing that...

Thanks for such a detailed answer.

It has nothing to do with GPU, your GPU usage goes down because you are CPU limited in this situations.

We just need RT of Nvida + DLSS of it.. Not software base but hardware

Buddy, the light source is processing the GPU, and my CPU is only 20% loaded.

This game has very poor CPU optimization, check the Digital Foundry performance review on YT for more details.
