In Forza Horizon 4, my FPS keeps dropping as I play. It starts with 200 FPS and after 30 minutes or so to 50 FPS. It's all on lowest possible settings. I've only noticed this after Steam got the performance overlay feature. So, there is a chance it was always like this. For comparison, there is Assassin's Creed Mirage. Played that for an hour, the FPS is all over the place but it's mostly over 100. Sorry, the colors in the graphs are not the same for both games. RAM usage and CPU clocks are on the right side of the graph. Laptop specs are 11th Gen i7, RTX 3050 Ti, 16 Gb RAM. Extra question: why does the RAM usage go down near the end in both games?

install XTU and max the boost

#

Is that an overclocking utility? It's a i7-11800H not a K-series processor. Should I still do it?

#

it technically is but stuff that is just something built in like boosting you can change, the normal amount is dumb

Okay, I'll be back after a restart.

#

It did not launch. Said my CPU/BIOS does not have undervolt protection.

#

it should have launched as you should anyways not have voltage control

intel blasts power fro short time then lower power to a lower vaule some cpu they have its 253W for like 30 seconds then 65W

#

For XTU, my BIOS didn't have any CPU section, so looks like I can't disable VBS.

#

I did look in the advanced section.

What are the chances that it's just a Forza Horizon bug? Assassin's Creed seems to be doing fine.

#

My Steam library is full of indie games. Nothing graphically intense, so can't really give it a fair test.

power starts at pl2 for short time then go down and then slower decays longer idk the data from the grapth is very bad

amber heron Aug 24, 2025, 2:02 AM

#

I have the CPU power data in the csv file. Yes, it starts at ~50 then slowly goes down to 28.

#

Anything I can do about it?

brisk elk Aug 24, 2025, 2:03 AM

#

Xtu

amber heron Aug 24, 2025, 2:06 AM

#

As I said, the BIOS does not have the option to disable VBS. It's not letting XTU to launch.

#

#

Wait, I'm reading it wrong. I'll be back yet again..

#

You can 100% turn off virtualization

#

Anyways just disable core memory integrity in windows

#

Okay, got XTU running, What should I change?
