Abnormally low FPS on ASUS TUF Gaming PC

Good evening,
I followed your instructions to the letter. Still, the game keeps showing my FPS at 58-60.

But if you don't have anything else in mind for the moment, I might not want to overuse your availability...! Because it's definitely better now, since I made the changes you recommended, I haven't noticed any drops. A big thank you for all the information anyway!

Yes, I will test modifying the in-game performance settings!

As for the Nvidia program settings, I had seen the option to add the game and I had already done it. It looks like this:


But I modified the global settings, following what you told me ("check in the settings list if it will use your GPU"): at the line "OpenGL Rendering GPU", the selected option was "Auto-select", so I selected the GTX 1650 (by the way, it didn't offer the other graphics card so I don't know if that will change anything).

This is unrelated, or maybe it's related, but there's a "symptom" that I forgot to mention.

When I'm in-game (only), and I try to switch programs (browser or software) using ALT TAB, my screen experiences glitches like this:

I have to repeatedly press ALT TAB several times to switch back and forth between the game and the other program so that these display glitches disappear (they then return later during my next gaming session, for example). Do you know what could be causing this?

Thanks again!

See you!

Hello,

Sorry for the long delay in replying. And thanks again for the time you’ve given me.

I wanted to take the time to properly follow your advice and especially to play several games to see if there was a real change.

Well, I'm pleased to tell you that the answer is: Affirmative, Chief!

I can now easily play at 110-120 FPS. There are still some drops when my laptop heats up after several games, but that seems normal for a laptop.

What worked, I believe, are mainly the last pieces of advice you gave me:

"'[...]Otherwise, try again in the NVIDIA Control Panel 3D Settings, Program Settings tab this time on the right of global settings.
Then add LoL if it's not in the list.
Then check in the list of settings if it's going to use your GPU."

"Did you test putting it on performance in the game (lowering the quality by 1 or 2 notches (from High to Medium) for environment, effects, etc.
Uncheck Character Inking under Effects Quality and Anti-Aliasing
and for your FPS cap, I suggest setting it to your screen’s refresh rate (120hz)
Try that and let me know if there's a change in FPS"

By the way, just one detail, I'm not sure I fully understood this last sentence: "set the FPS cap to the frequency of my screen," do you mean to cap it at 120 FPS? That's what I did.

As for the issue with my display bug with the pixels... your message scares me. Because that is indeed the case, the entire screen (window + taskbar) is distorted and pixelated. It’s just that it’s unstable, it doesn’t always cover the whole screen. In my screenshot, it was just a stroke of luck.
So I think I really have a small hitch with the graphics card.
I’m having a hard time understanding because the laptop is relatively new (and it was sent to customer service a year ago for a black screen issue).

Still, we can wrap up this topic!
GGWP!!
And thanks again!!!
