Hi, after many hours of trying fix this laptop for gaming purposes I finally found the solution(s).
Problem 1: Gaming starts with good framerate but suddenly lowers and stays low
Explanation: The cpu has a power limit of 28 watts during the first few minutes of gaming, this gives good framerates. After time has passes and tempetures are rising to ~70 degrees (which is safe), the bios decides to cut the power to the cpu to 7 watts which is too low for gaming.
Solution: Download throttlestop, this app allows you to take control over the cpu.
At this point you'll experience better fps but still lag
Gaming should be a lot better, but can be improved. Lets configure the GPU
Problem 2: Keyboard feels laggy during gaming
Solution: This is a realtek audio drivers, see this link https://neosmart.net/wiki/fix-realtek-audio-delay-lag/
Thats everything to it, after these changes this laptop performs beautifully, CSGO constant 120+ fps, pubg ~60fps.

awesome, it is really work. I can undervolt to -100mV, but laptop have i5-8265 (not i5-8250), and gpu undervolt to 0.85v. Overwatch work fine(60fps V-sync,ultra graphics) and withaot fps drop. Core temps is 85-90 C and freq 3.2-3.8 Ghz, gpu temp is 70-75C and freq 1300 Mhz. Keyboard issue I fix by change realtek driver to microsoft driver , but in my opinion sound quality was worse.

What should I have for undervolt if I have the I7 model? ( the Frequency -90 also ?)
Also who is saying there is a bios update soon? Any source that confirms it?

What is the launch date of your BIOS update? (it's on more information in the BIOS update in Lenovo Vantage).
@Legendz51 Thanks you very much for publishing the work around!!! I still didn't try it because it could be dangerous if the system never throttles in case of over heating, i will wait for the BIOS update and as omerico22 if i ever have problems i will give it a try!
On the other hand it's a shame we have to risk our laptops and void our warranty, personally i think is a right for us to have an update that solves the issue 100% since in the web page says "#game ready", and this laptop is far away from that. When we bought the laptop non of us thought that we would have to take this kind of risks in order to make it work in the intended way, according to the official advertising, we didn't pay for that.
To sum up, Lenovo has to take care of this and solve this in the proper way, and if not, everything points to, not just an error, but to a deceptive advertising....
