LOW GPU utilization AMD Radeon

[Hard Reset]

I noticed that during this game the GPU usage is not 100%. I don't know if this is a problem with the game or something with the graphics card drivers ?
Does anyone have a similar problem ?
I am playing at 1440p resolution. RX7900GRE , i5 13600K,
If I turn on MSAA or FXAA edge smoothing the in-game gpu usage increases . I think that without smoothing also the gpu usage should be 100% and only the fps should drop ?
I recorded a video , link below:

It's usually because GPU waits for CPU calculation for frame.

Usage of my cpu is low , I think 16 cores can handle this game well.

Doesn't mean game can use all cores to same level as not every logic can be paralleled to be split.

Watch the whole video , there I showed that when you change the smoothing settings the gpu usage changes to 99%.

Because GPU doesn't need to wait for CPU logic calculation like AI and units movement when in Pause which is why you get short increase of FPS after exiting options, or when you increase settings they will use more GPU usage as they will increase GPU usage needed to draw frame.

Next update also should improve CPU handling on camera movement.

It's not about being in the options menu, it's just that when you change the settings and return to the game, the gpu load changes. In my opinion it should be at 99-100% all the time.

It's not how it works, you can't force GPU do more than requested for frame as it achieves nothing. By increasing settings you simply give GPU more things to do while CPU calculates it things which is why it have higher utilisation on higher settings. If you reduce it finishes it work faster and waits for CPU.

In other games gpu usage is almost always around 90-100% , and in this one it drops to 50-60% . For me this is not normal .

And it explained why it happens. It varies for games, some are more GPU heavy, some are CPU.

Are you suggesting that 20 Threads and overclocking to 5.5GHz on my cpu is not enough for this game?

As i said

So yes it can't handle more frames than it can right now or rather how game can use it cores, which is less than what GPU capable of doing on it maximum load. Parallel programming isn't some magic of just "enabling more cores"

The game is not programmed to use 20 threads simultaneously (Edit to add simultaneous because the game does use more that 20 threads but not simultaneously)

So no matter how many threads or cores your CPU has physically the Gates of Hell software doesn't use most of them.

So most of your "CPU" sit and does nothing.

Software needs to be written and complied in a "special" way to make it symmetric multi-thread compatible.

On a "positive" note overclocking your CPU will improve performance for the threads that are running.

I posted up in another thread (on the forums) how you can view (in the Windows OS) the CPU usage, GPU usage, RAM usage and the number of threads a "process" is currently using.

In this situation it seems to me that the cpu is not the problem. The problem is either the game engine or the graphics card drivers .

[No h8 plz]

The game simply isn't very GPU demanding, it is very CPU and RAM intensive.

Apply Vulkan if you want increase GPU usage (DXVK), but this is strategy, here CPU is heavier used, and as this isnt new engine, it wont use all of your cores, hence you wont see high CPU usage. Game sits at few threads.
