Cyberpunk 2077 CPU perforamnce and easy AMD fix

[humbug]

Currently this game has some performance bugs when running on Ryzen CPU's, something to do with the games engine checking which CPU is running and then assigning it a code path, unfortunately at the moment its assigning Ryzen CPU's the wrong code path which has a detriment effect on its performance.

Fortunately there is an easy fix that you can do yourself until the Developer fixes this problem themselves.
The result of which is very good performance, see slide.

Toms Hardware had a look into this and provided some instruction and analysis.

How to Apply the Cyberpunk 2077 AMD 'Fix'
You can find detailed instructions on applying the fix in several locations; there's a PCGaminWiki listing, a video, and a reddit post with more info on applying the fix manually. New software that automatically applies the 'fix' is already in circulation, but always exercise caution with unverified software - there could be malware lurking.

Here's a simple bullet point list of instructions on how to make the change, but head to the linked resources above if you're not experienced with making these kinds of modifications:

• Open a hex editor to open the Cyberpunk 2077 .exe file
• Search the executable for the following hexadecimal string: 75 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08
• Change to: EB 30 33 C9 B8 01 00 00 00 0F A2 8B C8 C1 F9 08 (yes, you only modify one entry). (address 02A816B0)
• Save and exit.

And with that fix, the game code treats all CPUs equally and will spread the workload across all available cores. Now you're ready to test to see if your particular configuration responds well to the patch. We did just that with a limited selection of AMD processors to see which models benefit, but our testing is ongoing. We'll add more chips to the charts as results come in.

Is this a conspiracy or an actual coding error?

and you should move this thread to the GPU sub-section. Lol and watch it explode.

Its just an old engine, legacy, modern game engine don't vendor check anymore, no need for it.

Looks like they are aware. Fix incoming at some point then.

Yea that ^^^^ never download executables from the interwebs./

Come on. Not really that cut and dry. *use trusted sources *use your brain.

Fair enough

God i hate it when people agree. Merry Christmas

The real question is why they have not fixed it yet?

I thought they had now? i don't own the game BTW.... not yet.
