Hi first off, not sure whether to put this here or in pc gaming.

I upgraded my old gpu (nvidia gtx1080), to an amd 6900xt. I used ddu to get rid of drivers before installation.
The problem I'm seeing is games seem to have a wierd stutter. I currently game on an ultwide monitor connected via dp, and an oled connected via a dp to hdmi cable (that's cable not an adapter box, although I'm getting a hdmi 2.1 cable delivered today). I've got freesync enabled on the monitor, but not the tv (greyed out, I assume due to the cable) but the tv does say going into low latency mode.
As it's the first time I've used an amd card is there something I'm missing? Oh I am also using a 3700x and I've got that resizable bar set to on, and it's stuttering at 1080P.
 
I would just nuke the windows install and start over.. on a modern machine it takes less than 20 minutes to be up and running if you have set up your system properly to support this. Get the latest iso from microsoft that works with your key, if you are using windows ofc., and start from scratch. Troubleshooting an old install with swapped hardware will take forever. If you don't want to do this for some reason, then at least start by running the AMD driver installation, check of factory reset and don't wing off "keep user settings". After this then install the latest GPU and Chipset driver from AMD.com. Keep us posted.

It's tempting, I did a format last weekend (tbh wasn't expected a cheap card to come along so soon), and I've set my pc up so all games are not on my main drive and I back up everything to onesrive so shouldn't be too bad. I was also wondering what setting I should go for in the radeon centre.
 
I had issues with stuttering on my old RX 5700...spent ages tweaking things, uninstalling software, going pretty overboard and the only thing that fixed it was the Windows re-install.

Picked up a 6900 XT a few weeks ago and I just leave it on default settings for now....no need to mess. I'll probably try and get an undervolted profile going at some point but it's more than powerful enough for what I'm doing at 1440p. I used to OC cards to the limit, but with 200FPS in games on stock I can't be bothered now. :)
 
I use "sfc /scannow" in command prompt (as administrator) every time windows updates to avoid windows wierdness.

It's worth a shot as it takes a lot less time than a new install.

Just as an update, this is what i saw when playing BFV, the jump in the usage is when i realised i was only playing at 1080 not 4k (although strangley not maxing out my gpu). Obviuosly theres some spikes when dieing/respawning, but i'd have thought it should be flat otherwise. I'm using VRR, anti-lag, enhanced sync and running at full RGB, with HDR, however there is the occasional handshake issue so not sure if the cable is good enough, it's only a 3m one so should be.

you sure its not cpu bottleneck especially in battlefield? try limiting framerate to 80 or something and see if its smooth. i know when I had a 3700x I had to limit the framerate to 100 in battlefield 1 otherwise it would be very jumpy and stuttery.

If you log the frequency of the card you can check if the CPU is keeping it fed, if the CPU isn't keeping up you should see the card going into low power states while playing.
 
So I ended up just reformatting, but what's strange is that if I view afterburner from windows it shows me that, but if I do text and graph while in game its flat with spikes. Is there a reason why it's not matching?
 
Probably the polling rate difference between afterburner and rivatuner which shows the on-screen display. Rivatuner might poll slowly enough that only a few spikes come through and the rest are averaged out.

Yea maybe. Still investigating. Had to stop as my new "8k" cable kept losing signal with my TV, the pc then decided to not boot into windows so a fun day yesterday.
 
Just a thought. Have you updated the Bios on your motherboard and have you done any overclocking on your RAM. I have seen strange results when RAM is overclocked and the FCLK not being in sync. So if you are running 3600MHz RAM the FCLK needs to be 1800.
