Hello, I sold my RTX 3080 and bought a RX 6900XT.

With Call of Duty Black Ops: Cold War there are huge differences between these cards. The RTX 3080 with RT on was very smooth! The RX 6900XT is lagging...

Anyway, I don't really care that much about RT. So I turned that off. Now I have 144 fps. But I have a question: why does this card have hiccups while playing this game?

I presume you have the same issue I had with my 6800XT.

If you use MSI afterburner, check to see what the GPU usage is and what the core clocks run at.

Issue I had was that the core clock would drop a lot to 500Mhz and then jump back up when things got demanding. That sudden climb in core clocks and demand caused stuttering. So what I did was use the AMD software to raise the minimum clock rate to 2000mhz and it more or less solved my issue. When the game gets less demanding it still drops the core clock but not enough to cause lag spikes.

That's my "problem" yes, the speed is dropping to even 0MHz.

Why is this? And I think everyone is having this problem then? Is there any other solution?

currently, I cant find any other solution. It seems to be random. When a game isnt causing demand to the GPU, the GPU just drops power usage.

Try my solution and let me know.

Others is that possibly your drivers. I know this is commented a lot and you probably did already, but use DDU to remove Nvidia drivers.

Otherwise, its a typical AMD issue.

i have two 6900XTs and i do not have any kind of stutters,lags or similar in Black Ops..
but it loves to crash on RDNA2 in general (especially in Zombie/large maps for some reason)

you have "144 fps" ?
do you play in 4K Ultra or what kind of CPU do you have? i average at around 220+ FPS at 1440p Ultra and 300 FPS at 1080p

Did u run DDU after switching graphics card?

I did that when I had some performance issues with WHQL and Beta drivers this worked with my MSI Radeon RX 6800 XT Gaming X Trio card.

ATM I am running radeon-software-adrenalin-2020-21.3.1-win10-64bit-mar24.exe
1617945135728.png


Later today or in this weekend I am planing to install the newest Beta driver Non-WHQL-Radeon-Software-Adrenalin-2020-21.3.2-Win10-64Bit-Mar29.exe.

I have finished the main story of Cold War and didn't experience any hiccups running my AMD Ryzen 9 3900X with 32GB of RAM but I am also running the game of a Sabrent Rocket 2TB PCI-E 4.0 NVME SSD which is ultra fast and when I game Assassin's Creed Origins it's almost faster for me to load from a sync place then ride a mount and go there :roll:

Never noticed any issues with my 6900XT and I use a crappy 2700x although I play at 4k. Nevertheless, no issues here with the card and stuttering. Did you try the newest driver? If you didn't, use DDU to install the new driver.

I will try DDU! Any manual how this program works?
It is very intuitive. Just start it and pick AMD driver and uninstall. it is really simple.

Using AMD's own uninstaller didn't do it for me and DDU is easy to use not really hard.

Jay starts with DDU around 4:48 mins unto the video.

Also afterwards try unlocking the power limit this is what jay from jayztwocents did when he notice something was wrong, I do not know if this still applies but I do this on my own card and I don't really OC because I do not want to use the time to make it stable.

I think I fixed the problem. I deleted the drivers (not with DDU) and installed the WHQL version. This one works way better!

Is it normal that this GPU (6900XT) runs at 0 MHz in Windows?

My experience is that the 6900XT uses less power than the RTX 3080. Like 100 watts!

I do not think I seen 0 MHz in Windows what version and build of Windows 10 are you running?

I know I have shown @W1zzard a bug with GPU-Z on how to get 0 MHz to show up but that's with overclocking via the Radeon Adrenalin control panel.

When I'm just browsing and not moving for a second, the GPU clock, clocks itself down to 0 MHz. Memory clock is then like 20-25 MHz. When I move the mouse again, GPU clock is rising again.

I have the latest version of Windows 10 and checked this with GPU-Z yes. HW-monitor says the same.

Hmm okay, when you say the latest is that 2004 or 20H2? Because to be honest not everyone installs 20H2 because they have to do it manually in Windows update because Microsoft is not forcing it out.

20H2.

Update: clocks are still dropping...

Okay, personally I do not relay on Windows Task Manager for the GPU overview it's nice it's there but I prefer GPU-Z and MSI Afterburner with Riva stats when I am gaming.

I will take a look when I get home but that's weird. I've been monitoring since I got the card and never noticed that behavior.

I found the problem. I deleted everything with DDU (also Nvidia drivers). Reinstalled newest driver. Everything works fine, but when you play a game and then minimize the game and open the game again: after that moment the hiccups are a fact! No way they go away...

glad you fixed it (mostly).
