[SOLVED] Upgraded to a better CPU, worse performance.

[Ijustneedsomhelp]

Hello
I recently upgraded my CPU to a i7 9700k, what i had was i5 9400F. Now my question is, why is it that i am getting worse performance than i had with my i5?
I have updated all my drivers and even the BIOS to the newest version. When i played GTA on high settings with my i5 it ran great, no lag nothing, and now when i play it, there is so much lag in the city areas and even out in the desert or grass. I turned down the grass quality to normal but that doesn't seem to help the city lag.

I even bought Cyberpunk 2077 because i thought it would run great on my pc with atleast high medium settings. I went on the Geforce Experience optimizer and it was on max graphics, the same thing with GTA V, max graphics on the Geforce optimizer.
I think i will reinstall windows but i kinda don't want to download evertyhing again.
My PC specs:

Asus B360 F Gaming Motherboard
i7-9700k
RTX 2060 6 GB
32 GB Corsair Vengeance ram
1 TB samsung 860 SSD
2 TB HDD

What’s the cpu temperature when gaming? What speed (GHz) does it run at when gaming?

Oh the CPU temps are great, i have only had from 40 to maybe 50 celcius max. Well i have only seen 4.10 ghz when i was on my desktop but then i was doing a razer synapse update.

I got the cpu about 1 month ago, and i also bought a water cooling system for the cpu

First and foremost when u change motherboard or cpu, just do a fresh install; Anyways, by lag, what do u mean? that game has issues... did u check the fps, is it low than when u were on i5 9400f? coz i'm pretty sure, in this particular game, the gpu will be a bottleneck before the cpu becomes one... from my personal experience, this game is gpu intensive... use msi afterburner and monitor core usage, gpu usage, fps min max...

Okay i will do that, by fresh install you mean just delete everything right? Not keep my personal files. The lag when i get in to the city for example, i move my mouse away from it, and then back on it and it feels like 40-50 FPS. And i think that both the cpu and gpu can handle it pretty well? It wasn'tlike this on my i5 9400F

by fresh install i mean, make a bootable usb and reformat ur system , backup ur files and do a clean installation...

You can try deleting the old CPU cores individually from device manager/processors, and letting the CPU be redetected/reinstalled at next power on, which hopefully would result in the correct 8 cores detected.

(If your device manager shows the old 6 core config from the old 9400Fcpu, that is your issue)

I just reinstalled windows, there is no more lag in the game. Thanks for the help guys
