Question VERY unstable gpu usage in Fortnite with the RX580 4GB

[Rexaura]

Hi,

I have always had a bad stuttering problem in games. But the stuttering in Fortnite by far tops it all. I usually get around 100-80% gpu usage and every second it will drop down to 0. It's never at 100% for more than a second or two. My CPU usage is normally at around 50-70%.

I'm really not sure what could be causing this. It has made the game practically unplayable. What do you think?

Specs:
RX 580 4GB
I7-7700k
B250M Bazooka
1TB Sandisk SSD (Fortnite is installed here)
1 TB Western Digital HDD
16 GB of RAM
All software is up to date.

What temperature does the GPU reach?
What PSU do you have?

The GPU reaches about 83 degrees Celsius. I have no idea what PSU I have. This a prebuilt. Is there anyway to check the model? Would I have to take it out of the PC?

Maybe 4gb of video ram isn't enough?

The GPU might be throttling down because it reached the max. temperature before any harm is caused (but I am pretty sure 84c is the max. safe temp.)

Try monitoring the fan speeds whilst gaming and if they are low, try adjusting the fan curve or just make them run at 100 % while you are gaming (if you don't mind the extra noise) as fans are designed to safely run at 100 %.

As for the PSU, simply take the panel off your case and the PSU should have a label on it.

On my other computer I have a 4 GB GPU and Fortnite runs smoothly on max. settings using 2 - 3 GB. So I doubt VRAM is the issue.

You say the software is updated, but please tell us what driver version you are using.

20.9.2

It's been like this for every driver and I doubt it's a Fortnite issue or a software issue.

My fans are running at 100% and the graphics are on the lowest.

you need driver 20.10.1 or better, you will see those usage spikes go away completely once updated to those drivers, I had the same issue. Initially I believed I had a bitcoin miner accientally installed with some software. As soon as I got to the driver I mentioned it was resolved.

The issue for me anyway only really appeared after
20.8.3 or so but was fixed entirely with 20.10.1
