See if this works for you...
1. Open Nvidia Control Panel
2. Manage 3D Settings
3. Under Global Settings Select Power Management Mode.
4. Select Prefer Maximum Performance Mode...
5. Select Apply and Restart your pc..
6. Then try your games again
If this does not work then i cannot help you..
I already tried but it didn't changed anything, thank you for your help btw
Can you verify if the awful performance is due to your games running on integrated graphics or due to the severe underclock of your dGPU? I guess you can figure out by observing the parameters on task managers (so not to trigger the high performance mode with afterburner).
Also...
Changing components alone should not be a valid cause to void warranty. As long as you don't do it in such haphazard way to cause obvious damage I guess.
That sounds like a ripoff, even with my country's absolutely awful consumer protection most OEM still offer warranty after owners self upgrade/regular maintenance.
I know, but as the tech support said, I have to send the computer with the original components so they can check if it works whith them, of course the varranty is supposed to be voided only if I unscrew the motherboard from the case in order to acces to the keyboard. But if they effectiveley think I will pay for anything they are wrong, I think I would have to call for a consumer association to help me. Thank you for advices
Have you tried to manually point each game to use the dedicated GPU in the nVidia control panel?
From my experience with Lenovo laptop (have the Edge E530 to my parents), they had downclocked the GPU on this model with drivers from their website, so that it can fit the thermal envelope of this machine. Using drivers from Nvidia website, let it run free...aand overheat eventually and restart...had that many times.
My point is if you intend to run their machine some other purpose they had designed it to, get ready for some homework.
Yup I also tried this, I thought that the problem would concern only some of my games but I was wrong, I also reinstalled their graphics driver (from the offical Lenovo support page) but this haven't changed anything. So once I gather all the original components of the computer, I will run a last test and then send the computer to the tech support. Thank for trying to help me
And of course I have been doing homeworks about that little machine for 12 days now
