Good afternoon everyone!
So as of yesterday I noticed a massive fps drop on cs go and was like wtf just happened? Checked nvidia drivers and everything and it was all updated so what could be wrong.
Uninstalled the game and still got the same fps drop so I tried playing fortnite where I can see the gpu usage and temps with afterburner and I had the same fps drops while using the graphics card at 70%.
It is really annoying me as I can´t play like that and everything seems to be working fine as the graphics card is being used and the drivers are updated but still getting low fps.
Maybe I am missing some easy setting fix but if anyone can help I would be greatly appreciated.

Ps: Turns out Mystic Light was causing the problem. I installed it to show a friend how it works and what it does and it was after that that the drops started. I decided to uninstall it just in case before formatting the hd and it fixed the problem I am back at normal fps. Thanks for all the help and suggestions.

Overheat maybe? monitor CPU temps with HWmonitor.

While on the game menu it uses 67%gpu

CPU. Processor temps. Is it 30? HW gives you the min-max-current temps, whats the maximal one under load?

Your subject says game wont use gpu, yet you later say the card is being used, it's one or the other.

Your issue seems to be lower fps then normal, but that can be so many issues when you aren't giving much working info to go with.
Laptop/Pc, specs, etc.

I have 16gb ram I5-9600k and a GTX 1660Ti and never got this problem.
Only as of yesterday I started getting this problem on cs but now it seems to be on every other game. Low gpu usage and low fps as if the game isn´t using the 1660 but somehow the igpu

Was this right after the latest driver? Do you install beta drivers? Have you checked if the VGA is physically okay in the PC?

If it was just one game having issues I'd suggest right clicking on your desktop, opening the Nvidia Control Panel, and checking that the game/game.exe is listed in the Program Settings. If it had somehow been removed, you could simply add it and force it to us the Nvidia processor. Unfortunately, I doubt this is the case if it's happening with every game, but it might be worth checking just to rule it out (if you haven't already).

Think about
GeForce GTX 1660 ti -- Intel Core i5-9600K -- CSGO FPS Test Dust 2 Low - YouTube
The story that it does not work with such an FPS value?

Is it working with the onboard graphics function?
Are you connecting from the graphic board side?

You mean the onboard graphics from your processor? That can be toggled on/off in your bios.
Does it show in your hardware list items along your card? Go to device manager. If not, your cpu graphics can't and won't be used.

Also for a proper clean removal of nvidia graphics cards it's wise to use ddu uninstaller https://www.guru3d.com/files-details/display-driver-uninstaller-download.html i suggest going back one or two drivers, and not get the latest one (also be careful windows update doesn't try).

You haven't been messing with settings in afterburner, nvidia control center etc right before that?

Try running furmark/kombustor/anything else loading GPU to its limit.

Try rolling back the driver version ( to the previous version). May be a the new version is buggy....try the system restore function to roll back the drivers

The game is probably using the integrated graphics processor, go into NVIDIA Control Panel, and there in the manage 3D setting set the specific game or global to use the 1660 TI on the preferred graphics processor section.

Turn off the IGPU in the BIOS so your PC is forced to use the discrete GPU and see what happens. It's entirely possible your BIOS reset to defaults due to a power surge, finicky power supply, overclock fail, etc, etc, blah blah blah.

I have had graphics drivers crash in the past and when that happens the GPU goes into some kind of low power mode that causes very low performance until I restart the computer and the driver reloads. Maybe your driver got corrupted somehow and it is staying in that mode permanently.

Did you try reinstalling the driver or just checked that it is on the latest version? Even if you are on the latest version, it could be corrupt. I would try reinstalling the GPU driver or maybe roll back to a previous version. Maybe it updated recently and the new driver has an issue.

Or maybe like other have said, try disabling the integrated graphics from your CPU in the BIOS. I have never left it enabled, so I'm not sure exactly how it determines which one to use when they are both available.

If you turn on MSI Afterburner's on screen GPU stats while you are playing, you should be able to tell if the computer switches to the integrated graphics because the GPU won't be getting used at all and should probably drop down to idle usage, temp, and voltage.
