Frames drop on my Lenovo Legion y540

2020-07-09, 7:09 AM

I recently purchased a lenovo legion y540 with a i7-9750h and a gtx 1660ti - 6gb, and a 16gb ram. On the first week of using this new laptop, the performance was really good and I used to run my games on 144 fps at high quality, suddenly my fps dropped and I decided to reset my pc, I did that but I didnt see any performance increase, but I had an even further fps drop, I used to run the game at 144 fps, and after I reset my pc I started to run it on 80fps, my friends said why dont you do the "complete" reset which basically reinstalls windows, so I did it and the frames are still low, I thought that maybe the settings changed after my reset that resulted in the frames dropping? Something with the normal lenovo y540 settings changed and its not using the GPU as it should be. Does anyone have any fix to this because its really been impacting me and I've been trying to search for a fix.

 

 

Thanks and take care everyone

Not sure what's causing this.

Power Limit Throttling?

Thermal Throttling?

GPU Game Settings?

Other?

 

 

Here are some general tips

 

 

Make sure hybrid mode is off so you utilize the discrete GPU. 

 

Optimize nVIDIA Control Panel Settings (Guide

*edited*

You may want to disable "Battery Boost" & "Whisper Mode" from nVIDIA GeForce Experience

 

 

You may want to consider "undervolting" your GPU. (Guide)

 

 

You may want to consider 'undervolting' your CPU.

Guide Guide#2 

Throttlestop Guide 

Don't copy/paste values; this is a general guide.

Only adjust CPU Core & CPU Cache voltage offsets

-125 mv is a good, balanced, safe spot. Note this is a negative value.

 

 

If and only if 'undervolting' alone, didn't 'do the trick.' You may want to consider 'repasting' the CPU and GPU since idle temps are that high.

Guide 

Choose a thermal paste of good quality. Do your research.

Since it's a new laptop, I'd hold off on repasting. 

 

 

If you can't do those steps on your own, you may seek professional help.

I heard that changing the setting to High Performance in control panel will harm the GPU, is that right?

Selecting "High-performance nVIDIA Processor" as the preferred graphics processor [in nVIDIA Control Panel --> Manage 3D Settings --> Program Settings] to run a program/game shouldn't harm your GPU.

 

You are merely telling your PC to use 1660 ti instead of "Intel UHD Graphics."

 

Nothing more; nothing less.

All I have for options in the "Power Management Mode" for my game is, Use global Setting, Optimal Power, Adaptive, and Maximum Performance, I dont see anything else so by "High Performance" you mean Maximum Right?

I mistakenly was running in hybrid mode so my options were different-- sorry for the confusion.

 

You may try that, that'll ensure enough wattage is passed to 1660 ti.

 

I prefer you watch the guides.It takes a lot of time at first, but when you get used to it, it gets easier.

 

Also, make sure you play while AC adapter is plugged in

Ok i changed my settings to maximum performance and somehow i started to reach the 60s and 70s fps, it reaches the low 100s then it suddenly drops to the 60s-80s, I really dont know what the issue is anymore. Also, is this possible because of the fan settings? Is there a way to control it? Also, I still didn't try the undervolting thing you told me about, I'll leave that for the last thing ill do. Thanks for the help.

I see you have set "Max Frame Rate" to "ON"I'm not sure what value you've set it to.

 

Again, I'd take my time and follow the guides.

 

Hope you can regain high frame rates.

 

*Sometimes updating to the latest "GeForce Game Ready Driver" can help since a lot of patches are released.

Yeah i deactivated the max fps and it is still the same, no differance, I also saw a bit about undervolting, does it increase performance because it doesnt seem like it.
