4K Monitor: slow UI / not realtime RAM Preview

Hello,

Since working on a 4K monitor, After Effects UI is very slow and although the preview is fully cached to RAM, it does not play in real time.

I've read about a workaround for this issue, which also works for me: overwriting high dpi scale by the system. When using this option, it runs smooth and fast.

But it makes the UI blurry and that's why I am looking for a better solution.

The not real-time RAM preview issue is solved by choosing the "Full Screen" preview option. But the very slow/choppy UI happens all the time when not using the previously mentioned setting.

Windows 10 latest Build 17134,472

Intel Xeon E3-1231 v3 @ 3.4GHz

RAM 32 GB

NVIDIA GeForce GTX 970 (latest Driver)

Monitor: AOC U3277PWQU

After Effects, Footage, and Cache on separate SSDs

I have tried to activate/deactivate Hardware Accelerate Composition, Layer, and Footage Panels, with no impact on performance.

Any tips for this issue?

    It's end of 2021 and Premiere and After Effects still won't  work on a 4K screen... sucks to live in the future. I'll buy a 1280x1024 screen to use for work instead...
    I have a 12 core / 24 thread Xeon, 64GB of RAM, Fast SSDs, 1070GTX card... Can't edit a 4K movie.
    Premiere and After Effects are supposed to help the creative process. They are instead raising my stress levels and getting in the way of creating content.

    Same to me. Since 2014 I´m working with 4K and since that time Premiere is not able to play smooth 4K content on my 4K screen. FCPX and Resolve without any problems. How can this be??????

    Keep in mind Premeire Pro is more expensive than FCPX and Resolve. Adobe should just make a new program that includes the best of Audition, Premiere Pro, After Effects, Prelude and Encore. The price should be $9.99 per month. I used to recommend Premire Pro back in the CS 6 days but not anymore. FCPX and Resolve are great products for less money. I still use Premiere Pro because it works better than the other NLEs with 3rd party hardware but the average person does not have the same hardware I have.

    Wow! This helped with AE 2019! Don't know if it fixed in AE 2020 because the new version is even slower for me.

      I have the same exact problem. GUI super slow on my 4K Monitor.
      Adobe this is abysmal. Why can't you focus on stuff people really need.
      Speed to get work done. Instead every version has more of this cloud library content crap.

      That bug to vote up is from 2015 ... has 15 votes. Like that's going to help.

      Weird enough my 3 years old 5K-panel iMac, that i left for PC a while ago doesnt have these problems.

        Hi Kevin,

        This bug is 4 years old, since AE CC 2015. I still use CC 2014 because of that.

        I (and many other people) repported many times this bug since then but nothing happened exept that Adobe stopped the support of CC 2014 and we no longer can install it from the Creative Cloud...

          Hey Kevin,

          Using CC2014 is not even an option for me as I have to work back and forth with other people that are using the latest version.

          And using AE as it is right now, I'd quicker get cancer than get things done. This effectively puts me out of work, due to software that I pay for. It's ridiculous, how Adobe seem to prioritize new features over plain usability.

          I didn't even think that getting a 4K monitor would cause problems nowadays, they've been around for a while after all...

          I've got 3840x2160, 27" display, running Windows, I have to scale it 150% as otherwise you'd be glued to it.

          I think that has something to do with the sluggishness, also it seems directly related to the size of the timeline window.

          If I shrink it down it's as snappy as on my 1920x1080 screen, but as soon as I get it to a size I can actually use it in, it just bogs down to a point it's unusable.

          I'd name you in my will, if you could help me out!
