Input lag after changing stuff in throttlestop. (i7-8550U)

[PK_PATEL]

So I have an intel i7-8550U with GTX 1050. I do light gaming here and there. Recently for the past month, I have been trying to increase performance out from my CPU and I have got much information from learning about throttle stop throughs different threads and Unclewebb's replies to different users. I have come to the conclusion that with these settings in the screenshots after undervolting my temps are somewhat normal like 85-80 ish which is much better than previously, power usage is fine. But my main concern is after doing these tweaks my fps went up from 100 to like 150 which is a huge bump that I never expected but this is causing input lag only while gaming during the WASD movement affected my movement a lot. The issue was that when I press A key to move left it registered and then had a slight delay similarly for the D key which is so annoying because the FPShooter game mechanics require one to be steady while shooting. What could be the issue ? while does my CPU register it late!
I have both values for CPU cache and core same.

I see a couple of problems. The main screen of ThrottleStop shows that you have Speed Shift EPP checked but Speed Shift is not enabled within the CPU. Usually the BIOS enables Speed Shift by default but your computer is not doing this. If you are going to use Speed Shift Technology, you need to enable this in the TPL window. After you enable Speed Shift, press Apply and adjust Speed Shift Max to 40 and Speed Shift Min to 1. You will see SST in green on the main screen once Speed Shift is enabled.

The big problem is in the FIVR window. You have set an offset voltage but if you look in the monitoring table in the top right corner of that window, the Offset column shows +0.0000. This means your laptop does not support CPU voltage control. There was a BIOS update that has disabled CPU voltage control on many laptops. Not sure what laptop you have but if possible, try installing the previous BIOS version and maybe you can get voltage control working for you again.

Without voltage control, your CPU is running HOT! If it is constantly reaching the maximum temperature and thermal throttling, you are not going to get smooth game play. Your input lag might be because of the throttling that is happening. The BIOS fix that blocks CPU voltage control has also disabled the turbo ratio limit adjusters. You can thank Intel for this fix. The only other way to slow your CPU down is to lower the Speed Shift Max value. This might be a way to control the maximum amount of heat.

In the log file in the far right column when you see TEMP, that indicates thermal throttling. You do not want to see that in the log file. Thermal throttling is the CPU rapidly switching itself from 3700 MHz to 800 MHz, back and forth, hundreds of times per second. This safety feature works great but is probably not the best if smooth performance is important.

Another way to control your temperatures is to lower your turbo power limits. Your CPU can handle these higher power limits but your cooling system cannot. Do whatever works best to keep your temps below the 97°C thermal throttling temperature that your laptop is set to. Changing the thermal paste can help with temperature problems.

Once Speed Shift is enabled, changing the Speed Shift EPP value on the main screen is another way to control your CPU. An EPP setting of 128 might help reduce temps a little without sacrificing too much performance.

Thank you so much
I tried the BIOS to a previous version but I can't find it though!
My laptop is Lenovo Yoga 730 15"
Thanks again for sorting out my problem ! @unclewebb
