AMD 6800xt frame dips!

[OCNewbee]

So I just got my 6800XT and I am very very disappointed. Frame dips are everywhere!!! With my old 1080, frames were far more consistent. 

In particular, in Assassin's Creed Odyssey, the GPU usage is only 40~60% and it all of sudden dips to 30s and comes back up. Can someone help me on this. I really don't like these frame dips. BTW, I am so mad at Linus. He gushed over this GPU and he didn't tell me about the frame dips? What gives? BTW, after scouring the internet, I am not alone on this. There are numerous reports of 6800xt frame dips! 

 

My PC specs are in my sig. 

 

*possible culprits for frame dips

1) weak PSU? (the GPU powers are on a separate rail so this is not a problem)

-my PSU is only 600 watts  *edit, it is 650W* check the sig for full specs.

2) driver uninstallation was not clean?

3) AMD driver just sux

4) AMD card just sux

 

I don't know guys help me out here.

First of all, every card behaves differently, not only when overclocking. 

 

Uninstall all GPU drivers, even your old drivers for your 1080. Use DDU to do that. Follow the description step by step.

If it is not too much of a hassle for you, do a clean install of Windows.

 

Your PSU might be a problem, depending on how good your PSU still is and what other compenents you use.

According to TechPowerUp the RX 6800XT has a TDP of 300W and recommends a PSU of 700W.

Check how much Watt your GPU is actually drawing, and how much the rest of the system draws.

 

And maybe also check the HardDrive, on which you installed the game. Make sure its not installed on a old HDD. Open World games benefit from the speed of SSDs.

did it. didn't solve the issue.

I don't think that is necessary

could be... but do I really want to buy another PSU just to find out the problem is still there? I am cutting it pretty thin. When I inputted my specs, it comes out to ~540Watt which is close to 500.

I have no HDDs, I use only SSDs.

 

thanks for your input though.

I have a feeling this is more on the driver side of things. I need to find out a way to keep AMD from having variable frequency and variable power draw. Nvidia has a pretty static power draw and frequency. This is how NVIDIA keeps their GPUs nice and steady. AMD stupidly implemented a laptop solution on to desktop suite so I think this is why Radeon owner are experiencing this. 

 

I don't know. This is just a hunch.

more bad news. I just played CS and it is pretty stuttery. what the heck is going on...

[JediFragger]

6800XT and runs perfect on a RM650x (5600X/X570 sys), smooth as butter in everything I've tried (48" OLED). I'd wipe Windoze before running out and getting another though, just in case.

what exact psu?

ram config?

temps?

 

also do you play at fullscreen or windowed fullscreen?

 

try normal fullscreen with freesync/other off. also disable vsync

 

for me the stutters happen if i play any game at windowed fullscreen. that might not fix your problem but it is easy enough to try

I am playing full screen

still frame dips. not really stutters but dips. It sometimes dips to 2 frames.

[OCNewbee]

it seems like ac odyssey was the only game that had this problem. For CS, I set the minimum to 300fps and things were good again.

WHICH "SeaSonic 600W Gold" is this?

The SeaSonic Focus units has some issues with high power draw GPUs.

What PSU? I run mine off a 600W with no issues. Different models of PSUs will handle it differently though.

AMD is completely rubbish in high CPU usage, DX11 games. See this:

 

https://community.amd.com/t5/general-discussions/amd-when-will-you-fix-your-terrible-driver-overhead-for-dx11/td-p/298059

 

Odyssey is high cpu usage[lots of actors, open world] DX11 game = perfect recipe for disaster. One of threads is pegged by API draw calls, and frame render stalls until it resolve all draw calls. That's why its more stuttery.

 

If you plan to play DX11 games i strongly advise to sell AMD gpu and buy Nvidia.

I've researched this issue for a year, spare yourself troubleshooting and pulling hairs -it's AMD fault. They said they will NOT fix this issue EVER. So if you want to play odyssey with much smoother frametimes it's time to splurge on that RTX 3070.

idk about that, my Vega 64 did AC Odyssey okay

Show frametimes graphs and compare that to nvidia equivalent of that time or vs current nvidia gpu. Different architectures are affected differently. I found that RX580 was less affected than 5700XT, maybe because it had less frames, but AFAIK i was using FPS standarized tests. 

 

Something terrible happened with RDNA and onward. Seems that RDNA2 has the same problems. Anyway, API overhead in DX11 affects all AMD gpus, some more some to lesser extent.

 

I know that i won't buy another AMD product after RDNA fiasco. And its sad that they haven't fixed their drivers ever since. DX11 was left in dust bin for AMD driver team

Haven't played the game in a while, and I'm on a 3080 now. I won't go through the hassle of testing different parts so I'll take your word for it

What about background tasks?

Maybe your antivirus is running a scan or some other program is acting up.

 

See if you can put the game in window mode and open task manager on top.

Then check and see if the frame dip corresponds to a spike in resources from an app in task manager.

oops. all these years I thought I had 600w. Turns out I had seasonic GM 650

thanks for your informative response. I am so glad that I am not alone on this.

But I am a bit curious tho. (btw, i did not read the entirety of your link TL;DR) 

So here my shallow understanding. When a PC with AMD GPU (the RNAs)s runs DX11 titles, the CPU processes it first? And when one of the threads are pegged by API draw call, it causes frame dips. If so, then why is frametime still so bad even when I have an overclock i9 9900ks that is at below 50% usage?

 

I am sure you are correct but it could be an inherent problem with the anvilnext2.0 engine.

I use no antivirus *gasp*

I don't have any bloatware.

The frame dip corresponds with the power dips. In order to mitigate this, I put the power on 115% and I raised the min FPS to 300. This solved the stuttering on counterstrike.

Now, the frame dips has been isolated to Assassin's creed odyssey. I need to try other DX11 titles to see if other games are affected. If this is true, Linus really F$%^ed up.

Ok, but why would you change the GPU when its the CPU thats "stalling"? 

 

Same thing happens with a Nvidia GPU, if your CPU is 100%  nothing goes, even though you may have free cores that dont do anything at that point.

Not even sure who to blame here (if in doubt Microsoft I guess) but GPU brand isnt going to make a difference here.

Ironically, AC games are known to be CPU intensive, it could be your CPU is bottlenecking.  You have to check on each core/thread , if one is close to 100, that is your issue.

Due to how AMD driver is made, the draw calls use a single process.There is only so much a CPU can do, before the thread is overloaded, so you will feel very little improvement between let say ryzen 3700x and i10900k in this regards, maybe 15-20%. What can excarberate the issue is If the same thread used by draw calls is also used for some other calculations like sound, AI etc. Draw calls is usually a huge load for a thread taking 50-75% or more of thread performance, depending on the game. So you can clearly see why multithreading draw calls is that important. This is what nvidia driver do with DX11 applications. If you want to test this easily run 3DMARK api draw call benchmark with AMD gpu and Nvidia GPU. Nvidia performance is roughly double of AMD.

 

Better CPU won't help much, since single thread performance hasn't changed that much, and games develop to be more geometry/shading intensive. Sometimes the draw call load is so high, it overloads the thread and you get truly disgusting stutter. All while other threads are relatively lazying with 8 or more core CPUs.

I somewhat found a way to overcome this.

1) turn off your FPS/frame time counters (lol, it is a joke but it does sort of work)

2) use dxvk. It turns dx9, 10, 11 into Vulkan API (I used it to play assassin's creed and it was a lot better after around 30 minutes of playing)

 

Now I am little bit happier with the 6800xt.
