This game seems to be drastically and disproprtionally cpu or ram bound at 4k rt ultra.

[ThiefDeath]

I'vew been swapping hardware beween two of my machines and testing the performance of Hogwarts Legaxy at 4k ultra rt native. This is from a point very early in the game where I'm just in my house's room. I'm sure these framerates will be lower at other parts of the game.

Configuration 1:
RTX 4080-S
I9-14900k
128GB DDR5-5600
Windows 11
FPS at 4k rt ultra native: 90

Configuration 2:
RTX 3080-12GB
I9-14900k
128GB DDR5-5600
Windows 11
FPS at 4k rt ultra native: 75

Configuration 3:
RTX 4080-S
I5-14600k
64GB DDR4-3400
Windows 11
FPS at 4k rt ultra native: 48

Is this game really that bound to multipcore cpu or ram performance or there something wrong with my configuration on the 14600k machine?

its the engine not your pc , same on 1080p resolution , its ue emgine and not optimized by Warner Garbage

why does it work twice as good on the i9 though?

look at fps hicups from 90 down to 60 or less

Fps may go down but i'm not looking at that, i'm looking the game itself and its looks fine.

In general forum it is to be expected to be commented on other peoples comments.

There is something wrong with this system not cpu. There is not that much difference 14600k and 14900k. Something is very wrong with that system to be only 48fps vs 75 on a similar set up.

Configuration 3:
RTX 4080-S
I5-14600k
64GB DDR4-3400
Windows 11
FPS at 4k rt ultra native: 48

Are all three system in the same cabinet/case? How are the performance of fans and cooling solution?

There is no base line between all three hardware option here as you only list CPU; GPU and RAM, but there is lack of information for how good your cooling solution work. As an example when you use same system and only make change for CPU where you also have to remove your air cooler or AIO metal block on CPU you will also have variation for good contact your Thermal Interface Material will have between heatspreader on CPU and the metal block that are meant to transfer heat to air cooler or AIO water cooling solution.

As you seem to use DDR4 on your low end 14600K system, I would also expect that your mainboard will be different then for 14900K which have DDR5 RAM. DDR4 isn't necessary slower when you use DDR5 at 5600 MHz when you use DDR4 at 3400 MHz. It also depends if you are using a dual channel kit or you are using two dual channel kit (a total of 4 DIMM slot) where you should only use one dual channel kit.

In short you need to provide more information that only show different FPS between system if you want to claim there is something wrong with game or where to find out why your system have that large gap for FPS (as that also depends on where you test in game scenes).

Benchmarking isn't just to start three system and then compare, you need eliminate all possible difference between system as far as possible to be able to focus on what can cause this issue.

Double check that all in game settings are identical including resolution, if you use any upscaling like FSR/DLSS and that related settings etc.

Check that you don't have any background task running in Windows (use msconfig to have a clean start up with minimum background tasks).

Use DDU to clear out all left overs from earlier Nvidia drivers and re-install drivers to avoid that there is something related to drivers and make sure all three system make use of the same driver version.

I would also check if you have all cables like PCI express (12 PIN power cable) seated in connector ports as they should and provide enough power to GPU as it is possible that your GPU will run with only power from PCI express slot (rated for 75 Watt), but when you start to play games that need more power to your GPU it needs power from that cable that is connect between PSU and 12 PIN power connector.

Use MSI Afterburner and set it up to show power draw in Volt from you GPU to make sure it have enough power that it needs to run.

RTX 4080 make use of a 16 PIN power connector so that connector can be hard to know for sure if it is completely seated to have full contact with pins on GPUs connector even if it snaps in place. I bough a special cable from the same vendor as my PSU where made to make sure to eliminate any possible issues that have been reported on RTX 4000 series 16 PIN connector not to be seated correctly.

When you compare those system are you using the same PSU to power those system or different PSU as that could also have an impact on power delivery, if you have two or three different type of PSU.

Make sure that you are watching the same FPS and not low FPS (there are 1% low and 10% low FPS in general and the same for top 1%/10% FPS) vs avg. FPS or mix those FPS types up as those can be different and are measuring different things.
