Apparently tere is some quick fix for AMD CPUs.

I think it helps. My CPU usage jumped from 40-50% up to even 90%+. I think game got a little more smooth.

Seems big enough to justify a thread:

Credits go to: https://www.reddit.com/r/Amd/comments/kbp0np/cyberpunk_2077_seems_to_ignore_smt_and_mostly/gfjf1vo/

So I was struggling on my PC (AMD Ryzen 3600 / RTX3070) to get over 60 FPS. Whenever I changed my graphic settings to low/mid/high/ultra, the FPS stays the same. I saw that only 1 or 2 cores on my AMD were being utilized. So I stumbled on this post on the AMD reddit.

I did the fix they said there and I now have 100 FPS on 1440P everything maxed out with DLSS Quality.

My proof:

This is what you need to do (Basically just change the 75 to EB)

Step by step by /u/chaosxk

Step by Step:

1.Download HxD hex editor

2.Find your Cyberpunk2077.exe, i have GOG so mines was in Cyberpunk 2077\bin\x64

3.Make a backup copy of Cyberpunk2077.exe just in case

4.Drag Cuberpunk2077.exe to HxD, a bunch of hex numbers should appear (like 01 FF 0D, etc)

5.Press CTRL+F, change column to Hex-Values

6.Put in "75 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08" in the search string without quotes, those values should be highlighted

7.Copy " EB 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08 " without quotes

8.Back in HxD right click the highlighted values and select "paste insert"

9.Now go to top bar and click the save icon logo

10.Done

2077高画质，GPU吃满，AMD CPU占用却很低的优化补丁。

And here is the Hex-fix on v1.05

Search for:

75 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08

Change it to 74 or EB:

74 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08

or

EB 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08

And magic happens.

EDIT: Works on update 1.06 too.

Replace

75 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08

With

EB 2D 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08

This will re-enable SMT once again and fully utilize 8 core and above SMT. I took a big hit after the patch running at a solid 50% CPU, after this fix it's back up to ~%75 usage.

Give it a shot on your own hardware with your settings to see how it impacts you. Yes I have seen GamerNexus video and my results contradict his. Not here to argue who is right or wrong, just helping those affected by the new patch.

对4k分辨率下有用么？

我回去试下
Cyberpunk: 4K ultra, ultra ray tracing, DLSS quality
FPS(25~35)，CPU负载20~30%。
Ryzen 3700X(4242MHz)，
3080 Adoc(1890Mhz)，
DDR4 8*2(3200MHZ)。

调整后，再加上GPU手动超频了，FPS稳定32+，CPU负载50~60%。
Ryzen 3700X(4252MHz)，
3080 Adoc(2025Mhz)。


GPU主频超高了容易撞340W的功耗墙，游戏闪退，
降了点GPU主频，DLSS调到平衡，FPS稳定42+，基本可以玩了。

Tested on my Ryzen 3700x/RTX3080 in some random spot where I saw GPU usage drop.

https://imgur.com/gallery/sFew3PX

Top is without Hex Edit: 65 FPS, 47% CPU and 87% GPU usage.

Bottom with Hex Edit: 74 FPS, 68% CPU and 96% GPU usage.

This is everything maxed with Psycho raytracing if that matters.

And still I see videos from reputable sources saying it doesn’t make a difference. Well, it does for me.
