    @soberstone999 Your GPU is maxed out... Your problem is unrelated to what this thread is actually about. In fact, there's no problem in your provided screenshots.

    @Ubi-Borealis So before starting out I just want to mention that there are about 5 different kinds of performance issues reported by users in this thread, so it's a mess. What I'm reporting about is the performance lock on Intel CPUs causing unplayable framerates. What I also have to mention is that my hardware is not a bottleneck (unlike some other reports here that show 99% gpu usage or the other way). In my case the game is the bottleneck - because none of my components are being fully utilized during gameplay starting from TU 1.1.0.

    If you are encountering low FPS and CPU/GPU utilisation in-game after trying the above troubleshooting steps, please can you provide us with the following information:

    • When did this issue first occur for you? The next update after 1.0.4 — 1.1.0 and ever since. So that's about 5 months of this critical issue not being addressed.
    • Is this issue persistent, or does it only happen in certain locations/when carrying out certain actions? CPU usage is locked to 50% everywhere in the world after TU 1.1.0, reducing framerate from 80+ (prior to 1.1.0) to 26-30-40 with stutters (starting from 1.1.0).
    • What are your current graphical settings in-game? Intel cpu users are affected by 50% lock bug therefore graphical settings do not make a difference in framerate unless an user's GPU can not handle 30 fps in the first place. In my scenario, starting from TU 1.1.0 - 1280x720 50% res scale, all low - grants the same fps as 3840x2160 max settings. Just by looking at the last sentence you should see there is a problem with the game.

    My assumption on what causes the usage lock on specific Intel CPU models - the CPU does not have hyperthreading support but game doesn't perform a check/assumes it does and locks the max usage to 50% after TU 1.1.0.

    • Can you please provide a video that demonstrates the issue in-game? I've attached detailed screenshots with in-game and rivatuner graphs to the support case which show more than a video can.

    To put things into perspective, here is the performance on v1.0.4 sent by another user who informed us that downgrading to 1.0.4 is possible via unethical methods - i5-2500K maxes out a GTX 1070 on update 1.0.4 and, in result, achieves 69 FPS in the benchmark run. I can assure you nobody can get these performance numbers on Intel processors which do not support hyperthreading starting from TU 1.1.0.

    It would be important if you could forward this message to the developers:
    Starting from TU 1.1.0 - after noticing that the CPU is stuck at 50% I may have realized what the issue is. It's the lack of hyperthreading - and the game wants you to have it for whatever reason now. It would also explain why high end CPU users (9700K and such) have these issues. Here are all the processors that should be affected - sort by highest processor frequency and you will see that even recent CPUs are in that list:

    And an extracted list of some modern/semi-modern CPUs affected:
    i3-8350K, i3-9350K, i3-9350K, i5-7600K, i3-8300, i5-9600K, i3-9300, i5-9600K, i3-9320, i5-8600K, i3-8100, i3-9100, i7-9700K, i7-9700K, i3-8100B, i3-9100F i5-4690, i5-4690K i5-6600K i5-7600, i5-2550K, i5-3570, i5-3570K, i5-4670, i5-4670K, i5-7500, i5-2500, i5-2500K, i5-3550, i5-4590, i5-6600, i5-2450P, i5-3470, i5-4570, i5-4690S, i5-4460, i5-6500, i5-6685R, i3-8300T, i3-9300T, i5-2400, i5-2380P, i5-3570S, i5-3450, i5-3350P, i5-4440, i5-4670S, i5-3340, i3-8100T, i5-8600, i5-9600, i3-9100T, i3-9100E, i5-2320, i5-3550S, i5-3330, i5-4430, i5-4670R, i5-4590S, i5-7400, i5-8500, i5-8500B, i3-8100H, i5-9500i5-9500F, i7-9700, i7-9700F, i5-9500Ei5-2310i5-3475S i5-3470S, i5-4570S, i5-4460S, i5-7440E i5-9400, i5-9400F i5-8400, i5-2300, i5-3450S i5-4440S, i5-3340S, i5-6585R, i5-6402P, i5-7600T, i5-7440H, i5-8400B, i5-2500S, i5-3330S, i5-4430S, i5-4570R, i5-6600T, i5-6400, i5-6440E, i5-7500T


    And finally, here is my case id. It contains lots more info that I do not need to share here.
    I've sent it the third time now so please make it happen. Not just for me but the remaining intel userbase.

    @t1gfx I beg to differ, the problem isn't my GPU. My game runs fine, 60-50fps, but when this issue occurs (randomly) it goes between 30-20 fps and stays there no matter what I do until I restart. Soemtimes I get hours without problems and sometimes I load the game and after 5 mins the fps start dipping. I'm pretty sure this issue relates to me, I was one of the firsts to notice and make a thread about it.

    @soberstone999 Every issue should be fixed, but i also don't think yours is the same as the rest of us. The issue you're having exists not only from the launch of this game, but since AC Odysssey i believe. Where some people are playing fine and the performance simply turn to [censored] all of sudden, usually after pausing the game, no? Although it's just as bad as this one, the issue we're discussing in this post is kinda different, it started specifically with 1.1.0 update, and the FPS never runs fine since them, there are no good moments of gameplay, is just perma [censored] because the hardware is not being fully utilized by the game. Even though you're having a perfomance just as bad, your screenshots shows almost max GPU utilization, which shows the problem is probably something else. Also, two little tips that i've seem to problems similar to yours: try fast travelling to Norway and going back to england to see if anything changes, also try to stay a few good seconds on the menus, instead of going back to the game really fast.

    @shockb0lt Odyssey ran fine no issues, any other game ran fine, but not this one. Same issue or not they should still fix this mess no matter what, my game should run smooth as butter even with medium to low settings even on my low-end GPU (rip).

    @soberstone999 100% agree with you. Everyone should get a solid experience for what they paid for, and unfortunately, this game has not offered that for thousands of people. I only commented about the possibility of your issue being different, so that the Ubi support guy that is looking in this post has a better direction on what this specific issue is about

    Hello there!

    @T1GFX - Thank you for taking the time to share such a detailed report with us. We're aware that performance issues can have a number of different causes, and the development team are also aware of this when checking out the reports submitted to us. This is one of the reasons why we have asked players to try these troubleshooting steps if they haven't already, as these can help to tackle a number of common causes behind poor performance.

    Thank you for clarifying further how you have been affected by this issue. I've checked out your support ticket and collected your system files/accompanying images. These have now been forwarded to the development team, as well as the report you have shared with us here. I have included your information regarding Intel CPUs, as this could be very helpful for the ongoing investigation.

    Thank you for your additions to the discussion, @ShockB0lt, and for providing suggestions on how @SoberStone999 may improve their performance. I'd like to assure @SoberStone999 that your report has been passed on the development team for a closer look as part of the investigation.

    Thank you! 😊

    Thanks for the respond!

    For me the performance just tanks too much in areas like Fornberg or Vinland. Cities like Lunden or outside areas all run fine with over 70 fps (at least 60). I only notice the drops when the fps fall from 70 to 40 in places like Fornberg. It just feels choppy and I was able to run Red Dead Redemption 2 with at least 60 fps everytime on the same system, so Valhalla should run even better because RDR2 has much more detail and much more complex AI routines than Valhalla.

    It would be great if you could ask the team if they could give us the option to play in DX11 on PC because i think this would fix many issues. This is the first time they use DX12 and i think it was the wrong decision to directly make this the only mode to choose from because they also dont use any DX12 exlusive features like Raytracing or DLSS (PLEASE ADD DLSS TO VALHALLA!!!!).

    True but they are using Resizeable BAR (or at least attempting to) and that isn't available on DX11 ...... Plus Microsoft more or less forced them to go to DX12 so cross platform saves would work correctly

    I'm telling you this problem started when they started implementing Resizeable Bar into the game engine with update 1.1.0 ..... The simplest and fastest solution is to just dump it for now, take the extensions out and problem solved ..... Basically go back to the 1.0.4 build and add the new quests, features and bug fixes to that .... Management needs to realize resizeable BAR is just not going to work in this game engine right now

    Actually it is your GPU but not your GPU's fault ...... There is a VRAM memory leak caused by the Resizeable BAR implementation that was added to the game around 1.1.0 ..... It's going to work similar to a DRAM memory leak in that the longer you play the worse it gets as it no longer can allocate RAM (in this case VRAM) properly ..... The CPU is only going to work as hard as the asset streaming allows it to work, the FPS is only going to be as high as the asset streaming speed. Also Resizeable BAR needs PCIe 4.0 to work and it seems to affect Intel more because none of their CPUs support PCIe 4.0 like Ryzen has since the 3000 series .... Granted it shouldn't be a problem but only if Resizeable BAR is properly implemented and I'm suggesting that implementing PCIe 4.0 is messing with the PCIe 3.0 extensions/APIs for Intel CPUs more than Ryzen
