Massive CPU usage since next gen update

[Akboris]

This game used to run really smooth on my hardware, now it runs poo and Afterburner says my CPU is to blame, my CPU is getting old, but it is more powerful than any 2015 CPU. This update is to blame, but why? Why is the game suddenly CPU intensive?

This game has always been very CPU limited since its new gen update.
I don't know how you managed not to notice it with an old CPU like yours even with its slight OC.
What update are you talking about the very last one compared to the one before? Or the last one compared to the "old gen " version of the game?

CPU "power" isn't the only factor. There are features in a modern CPU that yours doesn't have. Ways of being more efficient with the power available.

Raw ghz isn't everything.

There was going to come a time when a game called upon these features of a modern CPU and yours struggles to answer. Like a grizzled war veteran... or tired old Witcher.

I have updated the title, I am saying since the next gen crap, and "always has" isnt the right phrase to use because this next gen change isnt very old, and this CPU utilization problem I am having is absolutely tied to these changes. The game runs really mid now, even with dx11 and to be frank this next gen update perfectly encapsulates what next gen represents, same graphics and ♥♥♥♥ frame rates

What features are those? I am playing DX11 mode on the same settings that I used to and getting 30% less fps and a bottleneck that didnt used to exist..

This is a 2015 game that was "given features" that to my understanding no one asked for.

8600k is the first 6-core i5, aka coffee lake. While it really is getting on a bit, it's not quite as bad as the 6600k I got rid of last year for CPU bottlenecks. Still, it's 6c/6t so no hyper-threading.

If you're really interested in advancements in cpus, there are big reviews for each gen, including silly "monster GPU at low detail/resolution" tables to make the differences look bigger. I've got the latest and greatest i.e. 13600k, which could partially explain why NG patch has run better for me than some others. Then again, its got DDR4, so it could be somewhat faster still.

This patch promised to fix low CPU/GPU usage issues, which could very well hurt older GPUs without hyper-threading.

Even the cheapest modern i3 CPUs are a bit faster in games than 8600K. Look up some tests on youtube, you'll be surprised:

If you read some other posts around here you would find that many people with more modern CPUs actually got a boost. A result of the patch utilizing their CPUs better, ways that may not be applicable to an 5 year old CPU.

The "next gen" settings aren't the same as the "old gen" ones.
The new gen "middle" settings are what the highest settings were in the old gen version of the game. That would explain why you have lower performances since the "new gen" update in DX11.
No need to talk about the ray tracing (in DX12) wich is very heavy on the CPU and the gpu...

you're confusing the concept, If after 4.03 update CPU usage is higher then FPS should be higher in more CPU demanding areas like Novigrad.

What exacly in game settings you have and what FPS you have right now on it. Did you tried delete all user.settings (dx12user.settings also) in ur documents/the Witcher 3 folder? If not then do it. Your in game graphic settings will be restored to default and you will need to set them again.

because the DX12 update is not real DX12 is a compiler to use from DX11 change to DX12 The next problem RTX need a massiv Cpu power and the cpu optimizing is complicatet but CD project is very bad in Cpu Optimizing Thats reason older Cpus have insane problem with RTX get a bottneck Example Spiderman remstarsted runs very well on PC with insane looking RTX Witcher 3 next gen before the last update game runs without SMT [ disable in bios Process lasso dont work] better i tested every update hope now the Cpu runs better

[R4zen]

That's not true, ppl thought that could be dx 12 wrapper but it was not entirely true, only menu interface using wrapper methods, the rest is pure but not good optimized dx12

[Pre55ure]

game is ruined in my book, was looking forward to the next gen update, so decided to do a play-through before it dropped to reach new game plus ready to play next gen with all bells and whistles RTX enabled and the whole shebang under it, boy were my hopes way too high, god knows how many months later its been since then and even now it still runs very poor. its still installed on my machine ready for some stable gameplay but at this point i really dont know why ?
Built my new rig under a year ago too spending almost 5 grand on it and the witcher 3 is still a challenge for the machine

rly but why is the perfomance without rtx even bad ?

If you don't use ray tracing, just launch the game in DX11 mode. It looks exactly the same as DX12 without ray tracing, but performs way better. The only reason to use DX12 is ray tracing.

DX11 version doesn't have DLSS and FSR they're greyed out. That's why I use DX12 version.
