I’m 100% sure it’s not a cable issue for many different valid reasons one of the main ones being that the cable is able to drive higher res monitor at higher refresh rate without issue.
Also if I just swap cables from my main monitor with the 2nd the same issue still happens with the 2nd monitor but only in Linux, never Windows.
Please bear in mind that custom tuning isn’t a guarantee between different driver versions; the voltage floor can shift with power management firmware changes delivered driver packages (this doesn’t overwrite the board VBIOS, it’s loaded in at OS runtime (pmfw is also included in linux-firmware)). I’d recommend testing with vulkan memory test with each Adrenalin update, and every now and then on Fedora too.
I’m aware. For now it seems to behave consistently. I observed higher avg clocks on Linux vs Windows with the same OC but then again it may be due to difference in monitoring SW or just polling rate.
To be fair when it’s time to upgrade the Linux support will be probably even worse since I would be upgrading to even newer stuff than what I have now.
I would hold on the conclusion for now. Steve from HW Unboxed tested both Zen 4 and Zen 5 with the “supposed” fix and both had improved performance so the rough difference between Zen 4 and Zen 5 remained almost the same as the issue was affecting both. We will need to see more tests though to draw a reasonable conclusion. We don’t yet know if this also affects older Zen 3 at all or not.
The monitors being flipped happened as well. I fixed that by flipping the DP cable order on the graphics card.
1.) IDK, this issue tends to manifest for me with different distros as well sometimes. Forgot to mention that it also happens if monitors go to sleep when inactive and on wake up the 2nd screen sometimes does not wake. That’s why I disabled sleep for monitors.
2.) So far works fine after disabling HW acceleration
4.) no need to waste both of ours time. The script now works fine but thanks for offer. I don’t even know what half of your sentence means :D
3.) On Windows I use MPT to further modify the cards behaviour like SOC voltages, clock, FCLK clock, TDC limits and power limits, etc… Basically I can easily squeeze 10% on top of the typical overclocking available via MSI Afterburner or AMD Adrenaline SW. #73rd place in TimeSpy for GPU score which is kinda ridiculous for air cooled card
Cyberpunk likes to draw a lot of current so my tweaks help alleviate the throttling caused by it in typical OC scenarios as the card hits current limit in the CP2077 benchmark more often than it hits the actual power limit. That’s why the lows on Linux are worse, it’s not related to CPU underperforming. I’d suspect that the lows would be actually better if I could uncap GPU TDC current limit on Linux. Averages would be likely still lower vs Windows due to lack of VRAM OC.
This is not really comparable and I would have to do proper test on both Windows and Linux with the same versions of the game but I’ve tested with the same settings which are FOV = 100, SSR = Low (because it performs like crap on higher settings for no visual benefit), everything else maxed out.
This is screenshot from the run I did in February with my Windows OC… (also had worse CPU and memory tune back then vs what I run now so results would be slightly better now as well).
And this is from right now on Fedora 40… not sure why CP detects it as Windows 10
Would be interesting to keep the same game versions and GPU,CPU,DRAM tune and do a direct comparison but I can’t really be bothered right now to mess with that. What’s important to me that it’s roughly in the same ballpark and there are no massive swings in performance so unless I keep a close eye on monitoring I can hardly tell a difference when playing.
Yes, I’m using the FOSS drivers. I’ll try to look at the logs next time it happens
RX 6800 XT
1.) I don’t think it’s a driver issue. For some reason the display just does not get picked up during boot. The system still behaves like there are 2 monitors connected though.
2.) Tried disabling HW acceleration in Steam, so far so good but haven’t used it for long enough to see if it’s completely fine.
3.) AMD changes VRAM timings with clock, it’s not just simple clock change, thats why also negative offset affects VRAM stability. I don’t think that CoreCTRL compensates for this with it’s VRAM tune.
Thanks a lot. This is actually quite simple and I’ve overcomplicated things for no reason. Also fully tested and working as I just got a kernel update.
I’ve understood your fist comment as if I needed two separate scripts files and one calls upon the other…
I wouldn’t call this a specialized setup. VRR has been there for almost 15years. I’ve dealt with VRR issues on Windows and they are still preset in some instances with mixed non-VRR and VRR monitor setups they just manifest differently on Linux due to different compositor. My experience last year on KDE 5 was fine in games and it was on desktop where VRR was causing me strange issues. Now I don’t have any issues on GNOME despite it being just and experimental feature still.
OC wise, yes. This is kinda niche and I’m glad that it at least works to some extent. I can squeeze more performance out of my GPU on Windows but even the SW that allows me to do it is not well known and very niche and finicky on Windows and for typical OC everything works fine on Linux except VRAM OC.
Weird mice… yes. After setting up my mouse on Windows I’ve saved my profile to the on-board memory and uninstalled that crappy SW so it’s not required for me to have my mouse usable.
HDR… I don’t really care about it right now. I’ve tried it and I still find SDR to look “better” in my subjective opinion.
I really have to disagree with your take that I would have to limit myself to “keep it simple” to use Linux since nothing is guaranteed and you will sooner or later run into some weird issue because of your setup despite thinking it’s “common enough”. Most of these requirements are not even weird in the slightest. And yes, I do appreciate the work that has been and is being done.
I haven’t and this goes over my head honestly. I’ve tried replicate what you said but I’m getting a “bash level too high” and it keeps repeating. I’m quite lost when it comes to programming and scripting so I’ve probably did something wrong.
But if you can be bothered to help me I’m all ears. These are the 2 commands I’'d like to run in script:
sudo grubby --default-kernel
output
sudo grubby --args=amdgpu.ppfeaturemask=0xffffffff --update-kernel output
You’re probably just lucky or you just don’t run any weird HW combination that may cause issues. For me Fedora is the best and most stable distro with least issues. I never used any distro on which I had no issues and I don’t believe there is such a distro anywhere. The issues usually just change to different ones when I switch.
While I never had issues with dual booting in the past, I’ve just found it to be annoying in general and even thinking about having to switch to the other OS because of X for few minutes made me not want to deal with it.
I also use Blender. It’s amazing. For my occasional office work OnlyOffice more than suffices. Photopea in browser as a Photoshop replacement or Krita in a pinch. OnShape for CAD for personal use. FreeCAD is nice too but has some severe limitations.
Will give it a shot
“Remember the nutella” - random Malian villager
It’s enabled in the Steam settings but whether it actually works I have no idea It’s possible it’s the root of the issue though.
I won’t say no to an invitation but I will say thank you very much instead
Thanks!
1.) will definitely give it a try 3.) I have set the amdgpu feature mask otherwise I wouldn’t even have access to the power limit, voltages, etc… but VRAM overclocking just does not work. Everything else seems to work fine.
