Weird mouse stutter issue after upgrading GPU

[NuclearCore_]

Hi, so i have a really weird issue right now. After my "old" (not even 3 years) 980ti straight up stopped working from one moment to another, my girlfriend gifted me a new graphics card, which is the 2080ti. However, with this card, I have experienced performance drops in some games. The thing is, the game would run normally, as it should, but whenever I start moving my mouse, it starts acting like a diashow, maybe displaying 5fps until I stop moving the mouse. Then it picks back up and continues running normally. Funnily enough, the velocity at which I move the mouse seems to impact how much my fps go down. Slower movements don't seem to affect gameplay as much as faster ones.

 

Now, I know that my CPU (i7 4790K) will be a bottleneck for the 2080ti in some games and will hold my fps back a bit. But for mouse movement to have such a drastic impact on gaming performance is just ridiculous. I just don't understand why that's happeninig. Especially since I have not touched any other system components besides the GPU. And with my 980ti, I've never had any issue like that.

 

Which is why I'm now asking for help on here.

 

What I've already tried:

 

DDU'ing my graphics drivers and reinstalling

Clean install of Windows 10

Both turning on and off Windows 10 game mode (which is pretty much garbage anyway)

Disabling any Overlays (UPlay, Steam, GeForce Experience, Windows 10 Game bar)

Closing any applications besides the ones required to play the game (like the launcher)

 

I have also had MSI Afterburner running in the background and it shows me how GPU usage pretty much goes down to a single digit number, whenever those framerate dips happen.

I'm on the newest NVidia driver (417.71), however the previous drivers had the exact same issue. I'm also on the latest Windows 10 stable release build 17763.253.

 

Now for the rest of my system's specs. To be honest, my whole system is sort of outdated from today's standpoint. And I plan on upgrading as soon as I have the funds available to do so.

 

CPU: Intel Core i7 4790K @ 4.6gHz

GPU: NVidia GeForce RTX 2080ti FE connected over PCIe 2nd Gen.

RAM: 16GB 1600MHz DDR3 Dual Channel

Motherboard: Asus H81M-Plus

PSU: Corsair CX750M

 

Also, I have two 1440p 144hz Monitors connected to the GPU.

 

I'd really appreciate any help from any of you and sorry for that wall of text.

What games is this happening in?

Mostly modern games, like Far Cry 5, Battlefield V, Rainbow Six Siege, Rise of the Tomb Raider, Grand Theft Auto V and Enter The Gungeon for some reason. At least those are the games I noticed it in so far. I don't have the card for very long at this point.

Another weird thing I just noticed. Controller input to move the in-game camera does NOT affect the framerate. Just mouse input does. Also, Moving around in the game world does not affect framerates either. Literally just mouse input. In menus as well. Whenever I touch the mouse, the framerate dips. No matter what else the game's doing.

Do you play in fullscreen, or bordered windowed? Try changing that setting.

Also try to only connect 1 monitor and then putting the game in fullscreen.

No matter if the game is in fullscreen or borderless window, the problem stays the same. Disconnecting one monitor and then playing in fullscreen also does not change anything. Thank you for the input though.

Does nobody else have a possible solution?

Alright, apparently, the issue is completely unrelated to anything I've tried so far.

 

My mouse's polling rate sitting at 1000hz apparently causes issues with games. I've turned it down to 125hz and now it's fine.

 

Guess this is resolved now.
