10x slower render on 25.4 and 25.5 than 25.3 or Beta (EDITED)

EDITED text
After update to 25.4 I have real trouble with rendering simple composition in my project. What was done in seconds, with new version takes tens of minutes.. 
In the composition are layers with different blend modes, all revealed by animated mask. 
Cache cleared, restart AE, restart of computer, updates.. all done..
The slowdown is really extreme. One frame lasts about minute or more. There are few layers with color burn mode, which takes ages to render ATM..
I can post the project.

AE25.4 @ Windows 10, 16 core AMD and nVidia 12GB, 128GB RAM. GPU acceleration enabled..

    Hi @nishu_kush . glad to see that you in adobe take care of this, it is quite annoying to work in two different AE versions..
    Sadly, beta did not fix the issue. Latest "good" version was i think 25.3, but 24.xx for sure
    Here is the link to my onedrive to zipped collected project. It is AE24 project so you can test render times in 24 vs 25. You can also check the render queue where are clearly visible render times of both versions. 
    And yes, we need to use 8K psd files often, this is just an example.

    it seems that latest two releases have trouble with handling large psd documents (8K). But other AE versions handle it really good. The difference is exponential, more than significant and literary unacceptable..So we have to use more than one AE versions for different projects..
    Please @Kevin-Monahan have you any information about some progress in this case? I sent you also Dm

    Hi vobrazovka,

     

    Sorry for the delayed response. If the beta version is working as expected, that means the issue has been fixed. If you'd like, Kevin and I can investigate. If you haven't already, please share the project and media files so that we can reproduce the issue.

    Here to help.


    Thanks,
    Nishu

    Just small update:
    The bug is not related to using blend modes. If I tried to swith it to normal, nothing changed. The bug is still with us in 25.5 - so we still need to use 25.3 or Beta. Render times of few projects are just unacceptable.
    The difference in render time between 24, 25 (before 25.4), 25 beta versus 25.4 and 25.5 is more than ten times slower in latest two official releases!!

    Hi,

    Thanks for the message. Your issue is quite strange. If you would not mind, upload the project and let me know where I can pick that up. Feel free to DM me the URL. I hope the team might be able to solve your issue once they take a look at your project. Sorry for the frustration.

     

    Thanks,

    Kevin
