Hi im having troubles fixing what i think is a GPU issue, When i play any FPS games the GPU sounds like it powers down for a split second and then resumes playing the game. It causes lag the exact moment it happens every time it does it and because i play mostly online FPS it causes me to die a lot. I have turned off windows gaming, nvidia shadowplay i even set my pc to delete cache files every 5 minutes but nothing is working for me is there a fix for this please? Btw ive noticed when playing games the CPU usage drops to 50% from 70%+ when it happens

I have a brand new PC set up and have never had issues like this with any other pc

RTX 2080 OC
I7-9700K w/water cooler
Gigabyte z390 gaming X
Gigabyte 750watt gold psu
16gb 3200mhz ram

which drivers are you using? are you monitoring GPU temperature?

Im using 417.17 drivers but it has been happening for nearly a month. Yes i monitor GPU temps and CPU constantly the highest the GPU has gone is 71c and the CPU is 64c

That is a bit peculiar... I don't have any first hand experience with troubleshooting RTX cards but that almost sounds like either an issue with the power supply or card itself. The easiest way to find out is to try the card in another machine if available, or removing it and trying another card (again, if available). Typically, cards will either work or not so the fact that it's intermittent comes across as unusual to me.

Try the following.

Select maximum performance in windows power profile.

Select the same in nvidia control panel.

I have just noticed it plays games fine until the ram cache goes above 2gb do you know of a program that will auto clean while im in game please?

Thanks, I have already set them to maximum performance i dont really know what else to do

Maybe the GPU is slowing down because it momentarily has nothing to do? That is, it's waiting for something else, like a file to load or something.

I would use MSI Afterburner and expand the graph (double click). Edit out all the unnecessary stuff (right-click, properties).

I would also edit the polling rate to 100ms vs 1000ms for the graph.

That should provide enough info to see what is happening to GPU usage and CPU usage during the dip.

What FPS game are you playing that causes this? Does this happen on every game you play?

Yes do this. See if you are getting a drop in CPU or GPU utilization that doesn't make sense. You can also see if it's downclocking the GPU or CPU at the same time. And as ZGR asked do you see it in every game you play or just one?

Thanks i will give this a try, Well it happens in every FPS game i play other than destiny which doesnt make sense

I have done what you said and from what i can see everything looks good apart from GPU and power % being erratic

What kind of FPS are you getting? What is your monitors refresh rate?

When the stutter occurs, your GPU usage and power % drop? What about your GPU core clock? Drops I am assuming.

There is a 2080 ti user on [H] that is experiencing stutters with no cause.

They RMA'd their card and the new one appears to have none of those issues.

Before doing that however, I would try to do more troubleshooting. I would definitely try maxing out the power limit, lowering the power limit, lowering core and memory clock, and try capping Framerate in Rivatuner.

I'm not feeling too confident about my suggestions, but it would really help to try moving the card to another system, or trying a different GPU out on the same system.

It could even be power supply related, but I have never experienced something like that on a desktop.

Something I would do is use NvidiaInspector to force pStates, but that will require some further research on how to use it. This will force the card to run in 3d mode.

Back with Kepler and Maxwell (600/700 series), it was possible to lock a specific clockspeed with .bat files so the GPU could not downclock until resetting it with a different batch file.

If feeling hopeless, I would RMA!

No the core clock never budges, Ive noticed since i did what you said earlier the CPU % is going up and down rapidly

That may be normal behavior. That happens to me when I game, but no stutters/hangs. My CPU usage is all over the place, especially when I game at a high refresh rate.

Sure, as long as the video in question isn't violating any rules. I'm assuming this is a video related to the stuttering which would probably be helpful.

Yes im uploading a video atm, It doesnt drop fps as often in BF5 as it does in other games but it does show how crazy the CPU is acting. I was watching the GPU usage while playing and it barely budged.
