chipset drivers for ACER E5-576G not working( kbl ironman_sk motherboard)

matheesha

i installed windows 11 insider build to my laptop ACER E5-576G but it's all laggy here and there, so I checked what caused the issue and I found out that the problem is with the chipset drivers [ I installed the driver setup utility and checked the missing drivers, and installed what it offered. but that drivers don't let the CPU to run at its max capability (it was 78% of benchmark results  I had with windows 10 with original chipset drivers)] , I downloaded and installed chipset drivers from Acer drivers site again but it's still the same.(shows that it installed successfully but I cant find them in device manager)
what can I do to get the optimal performance? 

hopefully someone can help me with this to find a solution.

ps; sorry for my bad English

Open advance power plan settings. Set max processor states to 100%
