I said it before and I'll say it again. It's not my job as a consumer to fix something I shouldn't have to. You do this tweak you're gonna screw up all future updates and the integrity of the games installation. I'll pass.

With my 2700X certain games perform better with multithreading disabled, Elder Scrolls Online is what I mainly play and I have to disable multithreading for it to perform best. I'm sure with certain processors maybe the 5000 series may not be effected in the same way due to their architecture.
I am guessing SMT degrades performance on some older models but not newer and since they just disabled it across the board for AMD some will see better performance out of hacking SMT in.

On top of this fix to actually use SMT threads on AMD CPUs, the memory pool values are set the same as the console settings...
Go to your CP2077 game folder > engine > config > memory_pool_budgets.csv
Set the values in that to something more appropriate for your system. Loading a save would previously take 2-5 seconds for me, now it's more like 1-2 seconds. I've only looked at one area but performance is up only a little from the RAM pool setting change, but other people are reporting massive performance increases depending on their hardware and area in the game.
I have no idea WTF CDPR are doing, but this has to be the messiest giant game release I've ever seen in terms of performance/bugs. I have no idea how they could overlook SMT being disabled for AMD CPUs, that seems intentional, since I don't believe those working on the game are that stupid.
And no, disabling SMT on AMD CPUs wouldn't raise performance on some chips, that makes no sense, this game will use all the threads you have. In my case, after the fix, all 24.

It was posted many times in Cyberpunk threads . All AMD benchmarks are off and game should be retested with this fix.
Someone got money from Intel 😀. It killed performance on my 3300X, it's night and day difference after fix.

This may have been fixed in a patch, my Ryzen 1700 does not show any unbalanced load across the cores like shown in some treads about this problem.

Odd, I have GOG 1.04 and I can't find it

Does this have any improvement on FX series, anyone here tried it so far with any FX chip.

Can anyone confirm this for 3700x?

This is a big screwup, but hopefully will be ironed out in patch but good can do fix sooner.
