I think CPU is bottlenecking GPU

[ATUM]

When I first bought the laptop, gpu usage was 98-100% and it runned just fine. But now 1 month later, out of nowhere, it decreased to 40-50% so did the fps. The temps never go further then 80ºC both in the CPU and GPU. When the game starts the CPU boosts to 3,7GHz, and the game runs just fine but 5 min later it locks down in 1,6GHz (base clock), thats when the gpu goes down to 50% usage and the game loses fps. After it locks down it doesnt matter what I do, even closing the game, doing normal things it only boosts again after 30 min, sometimes 1h. Can I do anything to make it stay in turbo? I really dont care about the temps.

 

My PC:

Acer Aspire 5

i5-8265U 1,6GHZ - 3,9GHz (turbo)

GeForce MX250 2gb

8gb Ram

256gb NVMe SSD <<< Games in here

500gb HDD

What game? I know my RBS 2019 with the MX150 lags a lot in League since the CPU becomes power limited. Do you see this same thing happening in benchmarks as well?

CS:GO is where I notice it the most it used to be like 230-250 fps now is only 130-140. In benchmarks it doesnt happen. I think is the CPU power limit but I dont know how to change it or if I can. When it boosts the consumption goes up to 30W and then goes back to 15W which is the TDP. Can I increase it permanently?

Try throttle stop.

 

Did you update bios recently? Maybe some power tables got changed from mfg.

 

Also, could be thermal paste cooked (unlikely on such a new product though).

 

Also could be vents. Clean em out and see if that helps.

 

Otherwise throttle stop or XTU to see what's causing the throttling (thermal or power limit throttling), and throttle stop to try to increase the boost window

You must be right on the cusp of the CPU power limit and then it throttles down after 5 minutes. I think the thermal limit on those CPU's is around 95 C, so I don't think it's throttling due to heat...
