High CPU usage?

[Bearnardo]

Hi people, does anybody has like a LOT of CPU usage playing? Im talking about 90%+ percent used, i have a ryzen 5 5600.

You are complaining and crying, but you have no idea how cool it is that the game can utilize multithreading to its fullest. This makes the frame time as smooth as line.

Aye. Very high CPU usage, and that's on a Ryzen 9. Takes up about 40-45%

I don't think CPU usage should be that high for... Well, any game really. It makes me second-guess playing the game really.

same i5 10500

Same with ryzen 5 7600x

Ue5 cant use more than 6 anyways

This game use 16 threads (and it's maximum), what are u talking about?

Any game can use any threads, depends on how much it was multi-threaded. Devs literally can parallelize any function for as many threads as it's possible and required - graphic, audio, AI, physic, network, scripts, anything.

Does it? It doesn't even come close to using all of my threads and I'm on a 9900kf. UE has a known bottle neck of limiting cpu core usage.

Lol, ppl literally whining about CPU Utilisation in Finals. Why? Cuz it's use all cores. I have 5800x3d 8/16 and when I'm playing my CPU loaded for 80-90%. Only a guy with 7950X said his CPU loaded for 50%, 7950x has 32 threads, 50% of 32 = 16 threads (or he got GPU bottleneck and CPU goes afk to chill a bit).

P.s. if you are monitoring CPU load via RTSS then you should know that RTSS is lying. Open process explorer and check it. Afaik you have to install RTSS 4.6.5 beta 5 to fix monitoring but I'm not sure. And again, it's true, except if your GPU is bottlenecking before CPU.

For some reason nothing but the Ryzen application can measure my CPU's load and temp. Speccy, CPU-Z, Windows, etc all fail at it

Windows CPU scheduling absolutely works. For example how come you're not able to completely freeze up the OS, or atleast a single thread, by writing a program that just runs an infinite loop? Because the OS, with the help of CPU hardware, has complete authority of what and how much of it is able to execute on the CPU.
This is something that the OS has constant and precise control over. And when combined with windows's scheduling priority mechanism, it ensures everything critical to the operation of the OS is never interrupted.

However, if you still want to believe we live in the 90s, I can provide you with the exact x86 mnemonics modern OSs use to achieve this and explain in detail how and why they works the way that they do.

Not really, When your CPU is being physically bottlenecked, no software side optimisation will do anything. To work properly windows reserves resources from CPU in the cache from time to time to get instant response from calls made by OS to CPU. 100% cpu usage delays this process causing malfunction. Developers know this and optimise games properly by releasing system specifications which indicates on what kind system the game will work. when you cpu is being utilised constantly 100%, windows will wait for any kind of operation until the CPU has time to allocate time to windows. The CPU being busy allocating resources to the game, will start ignoring calls from any other sources be it windows or any other software, the cache will be constantly filled up with hardly any room left for windows. This will cause several malfunction and you can see in these forums people with 100% cpu usage has several crashes, hardwares like keyboard and mouse getting disconnected, audio acting weird. All these because of heavy CPU usage, even the the p-cores and e-cores get confused how to handle it because it is getting less time of engagement of the operating system with the CU. You will understand none of this anyway so no point in explaining stuffs to your 90's brain any further. So yes this game is horribly optimised because the devs didn't test a wide combination of hardwares. 100% gpu usage is fine but 100% cpu usage is not.

Please do clue me in on how the OS "reserves resources from CPU in the cache". As far as I know the programmer has no control over what gets cached or not. I think at best CPUs allow you to mark specific pages as NOCACHE, but that's about it, and I mean in which case, software could easily get rid the problems you mentioned (since the operation of setting page properties is fairly cheap), if they actually existed, which they don't. The issues of audio stuttering or other hardware disconnects under normal circumstances is infact cpu scheduling working as intended, just the priority values of certain processes might not be appropriately set for the current situation (and also that their cpu is ♥♥♥♥, and likely couldn't run the game in the first place). Here though I think most likely it's just a case of people having very little ram which gets filled up almost instantly and forces the CPU to start pulling memory from the pagefile of some ancient 5400RPM hard drive.

I call ♥♥♥♥♥♥ optimization.

This, game visually isn't anything spectacular. TBH I can see this game being playable to about the same level of quality, gameplay wise, on the OG XBOX but at worst the 360. Given what this game shows us even with crappy optimization there are serious flaws here. I'm a gameplay over graphics guy (or rather make it stylized and save my computer some work), but this game should in no way demand Next Gen consoles or be demanding on the overwhelming majority of PC built to be able to play games. More than likely this is a yet another tech demo for the new Unreal engine.

After playing 30 hours, I haven't come across any sort of high CPU usage and I have an i7-12700f. Could be registry issues, drivers, bottlenecked, game settings, and GPU settings.

[!Zosma!Kiddara!EXAVOLT]

5600x pbo c0 with 7700xt oc. The ♥♥♥♥ just destroys the cpu.

[VIKIO]

did anyone miss the point, that the game has almost 100% cpu and almost 100% gpu usage IN MENUS? thats not normalin that is very very bed. you should check him pc

[₪ REN ₪]

im just in the menus and my cpu temps go above 70c.. 85c ingame.... while on other games I barely reach 65c (mw3, hunt showdown, ready or not).. I already replaced my thermal paste but nothing seems to work. I turned graphics and raytracing from epic down to low and it reduced temps by like 5c.... my gpu stays under 60c the whole time while playing.
