Then it's not related to HWAccel.

If you have spare drive, then you can try if clean installation fix the issue.

If nil help, then may be other hardware issue (since 5700XT is widely used for a while now. So, I assume that's not macOS GPU driver issue if can't be fixed by clean macOS installation).

Did a fresh install of Big Sur on SATA SSD. Still has stutter problem. Previously I had Monteey on SM951 drive. I am still using OpenCore from SM951 drive but I believe that shouldn't affect anything?

Any other ideas or what I can try? I've attached a video of me just moving around finder. Even doing that causes stutter. It can be seen at ~3 seconds & ~11 seconds.

Which CPU model? I wonder if that's CPU single thread performance related. Can you see any process stay at around 100% when that happen?

Also, you may consider open a new thread for this issue, because I can't see any reason this is GPU HWAccel related at this moment.

Can't see anything suspicious in activity monitor.

Is there anything else I can do to completely rule out HWAccel? I guess going back to original gpu and high sierra would be only other way?

The HWAccel is a function to deal with video codec (mainly H264 and HEVC). In your capture, you just moved a window on the desktop, there is no video codec decode / encode involved. Therefore, not HWAccel related.

The remaining part I will discuss with you in the new thread.

Think I found the issue. Posted in other thread. It wasn't HWAccel as you mentioned. Thanks for your help
 
Looking for some troubleshooting advice, please.
Mac Pro 5,1 - OC 0.8.0 - Big Sur 11.6.5 - Radeon RX 580 8gb - 64GB RAM - NVME w/Mojave and Big Sur - Titan Ridge 2.0 - BT 4.0
Getting very random system freeze. Mouse freezes then about 15 seconds later OS restarts.
Happened about 6 times today none quite the same as far as what i was doing.
I tried taking out and/or disconnecting every SSD or HD other than the NVME and it still occurred.
Ran first aid on all disks.
Is it safe to do a NVRAM reset running OC 0.8.0?

On your keyboard > press: 'CMD + space bar' and type "console" (without the quotation marks of course).

Within the Console app (on the left hand side menu) > navigate to 'Crash reports'

What do you see there?
 
Thank you for answering...So i went to the console and funny enough as soon as it opened and i moved my mouse a bit Big Sur froze...LOL....i had been up and running for about 2 hours.
Anyway, at least I have a new instance of a crash....

Here is the actual crash report...and it happened two more times. I have also attached a report from Mojave after a Big Sur crash...

Hi guys,
Couldn't find any topic about that, so I really hope to find some help.
I could notice after upgrading my cMP 5,1 to Bir Sur (OC 0.7.9) my memory modules are getting into conflict. I have three 8gb modules in each tower (OWC modules) properly installed but no matter what combination you try, I'm always getting a red led lit on the second tower.
Does Big Sir have anything to do with that? Really weird, never had an issue with memories in 10 years.
 
3DXmac...are you saying you are having the same problem with Big Sur freezing up?
Funny you mention OWC RAM....i just got a delivery of 8x16gb from OWC.
I have a suspicion that the 4x16GB Micron dimms in my Mac Pro may be causing the problem.
I am about to find out once i swap them.

In the past I had problems with HP modules from different batches, since then always bought modules memory from OWC. Never had an issue. They are not ECC modules, but at least they are more affordable. Checking my north bridge paste now, I've read it could be some overheating.

Sorry, little advice. If I'm not wrong go with 3 modules for each tower, that way it will use 3 channels instead of two, resulting in faster data traffic . Maybe someone could confirm that.

You should know that MacPros only accept ECC Modules.

And yes, three is the magic number. Unless you really need that much RAM for your application and don't care about the somewhat lower performance...

try clean format and reinstall. Also, what brand is NVME? Try Catalina.

You are right, I apologize for the mistake. I wanted to say about registered modules, they are twice the price.

I am really hoping to figure it out before doing a reinstall. Catalina is not an option for me. Need to be running Big Sur. This MacPro is used in a work environment. Funny I am not sure what make the NVME is, I bought this Mac Pro a few months back on ebay.

I think its a Western Digital...name starts with WDS...

So what you are saying is use only 96GB and leave both #4 slots empty and that will actually have faster performance?

Samsung NVME has a bug, which precludes it from normal booting in AFPS and potentially may result in data loss. If you need Big Sur, reinstall Big Sur then. Just backup main data and go.
