  • Hello Rawalanche,

    Thanks for writing in. I'm sorry to hear that you're experiencing difficulties with Bridge in Unreal Engine 5. Please keep in mind that Unreal Engine 5 overall is still in Preview, meaning that its functionality is not yet production-ready and that issues are still being ironed out.

    While I haven't been able to reproduce the UI issue that you've mentioned, I would be happy to take a further look into this for you. Would you kindly provide a screen-recording of the issue as it occurs and upload it to YouTube or Streamable.com so that we may view it?

    I look forward to hearing from you!

    Here you go:

    The UI element highlights lags severely behind the cursor movement, and pretty much any UI interaction such as click of a button, switching category, opening details, etc... takes several seconds to complete. Many of the UI elements, such as scroll bar don't even respond on the fist click, and take multiple attempts to even respond to mouse cursor interaction. This is on Ryzen 9 3900X, with RTX 2080Ti with latest drivers on Windows 10.

    Mind you this is not an isolated issue. I've asked several of my colleagues to test it as well and none of them described the UI performance as acceptable.

     

    I have a hunch that you will claim this is either a hardware configuration issue or internet connection speed issue. Here is a recording of a Quixel Megascans library in a Chrome Browser on the very same hardware with the very same internet connection:

    No UI highlight delay. Clicking the UI elements always reacts immediately and on the very first attempt. Scrolling is always smooth, not choppy. If this was a hardware or internet connection issue, the performance in the Chrome version of the library would not be acceptable either.

    Here is one more video comparing the performance of Quixel Megascans Website vs Bridge Standalone vs Bridge Integrated in UE5:

    Same hardware, same internet connection speed.

  • Hi Rawalanche,

    Thanks for getting back to me and for providing the example screen recordings! Please note that any inquiries made regarding internet connection or hardware configurations by myself or other support staff are not claims of any error on your part, but instead a part of our troubleshooting process to make ensure things are set up and running smoothly.

    Since you've confirmed that the issue is not related to internet connectivity, the next suggestion would be to check for any updates to your GPU drivers. Please also ensure that you're running the latest version of Unreal Engine 5, Preview 2, and not one of the previous releases such as Preview 1, Early Access 1, or Early Access 2.

    While I haven't been able to reproduce the issues you're encountering while working with Unreal Engine 5, I did notice a substantial drop in UI performance such as you've mentioned with the highlighting of assets while attempting to take a screen recording of my own. 

    I apologize for any inconvenience that this UI performance may have caused while Unreal Engine 5 Preview is still in development. If there are any available, please let me know if there are any noticeable differences after your GPU drivers have been updated.

    I anticipated the claim it's an outdated driver, so I mentioned above that I am using latest nVidia driver. But I did not anticipate the excuse I am using outdated bridge, my bad:

    So once again, the video above is from UE5 Preview 2 using the very latest nVidia drivers. If anything, the lag seems to be a bit worse now. The laggy highlight animation seems to be interrupting the scroll effect, so if user just merely scrolls down, if the cursor is over the thumbnails, the scrolling will be extremely choppy and take several seconds to complete.

  • Hello Rawalanche,

    I apologize for my delayed response as I was out of the office.

    As mentioned in my previous message, inquiries about how you're set up, including questions regarding drivers, version numbers, etc. are a part of our troubleshooting process to help get things running smoothly. I apologize if you see them as "excuses." I assure you, we're only trying to help!

    Since our last correspondence, we've launched the full version of Unreal Engine 5. If you haven't already, please update to the full version of UE5 and observe if the issue persists.

    Hi,

    I am a bit confused about the suggestion to observe if the issue persists. Was there any specific Bridge update dedicated to addressing the performance issues in UE5 final release? 

    I mean, you probably come in contact with the Bridge even more than I do, and you were able to reproduce the issue on your end too. If you tried the Bridge plugin in UE5 final release, and still encountered those same performance issue, what would make you assume that they'd suddenly vanish on my end for no reason?

    I have tried UE5 final release Bridge plugin, and of course there is absolutely no change in terms of these performance issues.

  • Rawalanche,

    Thanks for getting back to me. I apologize for any misunderstanding. To clarify - I was not able to reproduce the same issue that you're encountering when working with Unreal Engine 5's official release except for when I attempted to also take a screen recording of my own, as mentioned above. 

    To further clarify, many updates have been made between the Early Access, Preview, and final release builds of UE5, including those related to Bridge updates, stability, and performance. Because we always suggest that our users keep up to date with the latest releases, and because I did not experience these issues on my end with the full-release version of UE5, I simply wanted to ensure you were running the latest build.

    Since our last correspondence, I have also heard from another member of our community regarding a similar issue, so I'd like to reiterate that your concerns are valid and that we are speaking with our developers on behalf of this issue so that we may continue to improve the experience of using Bridge with Unreal Engine 5.

    To compare your experience with the other user who reported a similar issue, I'd like to ask if you're using multiple displays? While I have been unable to reproduce this issue, it may be because I am using a single ultrawide display. Our other report came from a user who mentioned that they were using a multi-monitor setup and that after running everything on a single display (I.e. not separating Bridge off onto another monitor) that the performance markedly increased. Does this mimic the experience you've encountered?

    I do use two displays. I tried turning off the secondary one completely (Using Win+P key menu and selecting the PC screen only option), but I saw no change in performance at all.
