laptops Acer Swift 3 experiencing frequent and dramatic frame drops

[Kjaxs]

My acer swift 3 sf314-54g-52lb with a core i5 8250u and a mx150 starts dropping frames every 5 seconds from 60 to 20 and in other games 120 - 20. I have been using throttlestop to prevent thermal throttling. this idn't happen before i used throttlestop. here are a few pictures of my throttlestop setup under load. is there anything that i did wrong in the settings?

Probably thermal throttling. Consider doing repaste. Or try to lift the rear of the laptop with something like a book

 

You've undervolted wrongly. CPU cache needs to be undervolted too

 

Also change long power max and short power max to 15. Use default turbo ratio limits

 

Consider undervolting GPU too

thanks, really helped more than i thought. its not throttling or droping frames. i was able to increase the settings.

When using ThrottleStop you need to under volt both the CPU core and CPU cache equally or else your under volt will be ignored.  Your screenshot above shows +0.0000 for the CPU Cache Offset.  That means your under volt is not being used.

 

There is a check mark in the PROCHOT 98°C box.  That indicates that your CPU has been thermal throttling.  This can cause sudden drops in performance.  Your Turbo Ratio Limits are set to 18 which cuts your CPU performance in half.  Is this really necessary?  If your cooling is really that bad then you should try to do something to fix this problem.  The heatsink and fan that Acer is using must not be installed correctly or else it is garbage.

 

Set the Turbo Time Limit back to the default value which is usually 28 seconds.

 

The Turbo Boost Short Power Max box needs to be checked or this setting will not be sent to the CPU.

I undervolted the CPU cache and changed the short and long power max to 15.

 

With that, i have started to get a different problem. my frames in game may not be dropping, but i can see a very choppy 40-50 frames or so (personal judgment) while the game is showing a total of 70-80 frames. I am using a secondary 1080p monitor connected on the HDMI port without Free-sync enabled and the laptop screen turned off

have you reset turbo ratio limits?
