Ever since the last two updates I have not been able to playback high resolution 65x LUTS applied with Lumetri without experiencing massive frame drops. It plays back just fine in older versions, and I have rolled back to use the older version with great success twice now.

 

Something in the last two updates just straight up breaks playback of these high resolution 65x LUTS in Lumetri and Premiere Pro.

 

For reference, I edit on a Windows 10 PC with the latest updates, i7-6700K, GTX1080 and latests Nvidia Studio Drivers. The LUTS I use are the GHAlex LUTS.

Thanks for the reply, sadly it didn't help. I deleted all the Media Cache files like described in the link you send, but stutters and dropped frames are still happening just the same as before.

 

It really seems to be related to the high resolution 65x LUT, and something that broke in the last two updates. When I disable the LUT in Lumetri everything runs perfectly fine, but once it's enabled it starts dropping frames all over the place.

 

When I roll back to 14.2.1, everything runs smooth like normal again while using the 65x LUT.

I meant to type when I roll back to version 14.3.1.
