Premiere CC 2018 Playback Delay after pressing the Play button

I desperately need a fix for this. Same issue, started shortly after upgrade.

ryzen 1800x

64gb ram

980ti

Absolutely the same problem in CC 2018 (in 2017 everything is fine)

I also have the same question, I thought I was the only one with this problem but apparently not. it is quite annoying in cc 2017 it did not happen, HELP!

I have a similar problem-- only my delay is at least thirty seconds long, and sometimes, more than a minute. This is extremely frustrating.

Windows 7, i7, 16 gig memory, GeForce GTX 1080 card.

Probably going to roll back to the older version.

Same issue occurring here. CC 2017 playback is instant when using spacebar or the play icon, but there is a 0.5 to 1 second delay when performing the same function using CC 2018. Nothing has changed in my PC specs and the Premiere preferences are identical.

If I use Mercury Open CL the delay is constant (half sec) but if I change to Mercury Software Only then working with no delay. I think, the problem is the Premiere CC Open CL propulsion.

Sorry for my bad English..

I have the same problem, including stuttering on audio and/or video every 2-3 seconds. As much as I like the new version, I can not work in these conditions  and I also reinstalled  the old version until the issue is fixed. Even in Media Browser the same occurs.

When I switch to Mercury Software mode the delay problem is no more but the stuttering remains.

In cc2017 didn't encountered these issues.

My system is:

GPU GTX 470 1,2GB

CPU i7 6850k

RAM 48GB

PS: I just replaced my GPU with a GTX 970 4GB and the problems persists. Soon I will do a reinstall to the OS (Windows 10 Pro) maybe something is wrong in current installation (although I freshly installed the OS on the Fall Creators Update release day)

you can switch to Mercury play back engine software only from CUDA

it will be faster when you are working on the timeline

but get slower on colour grading

This issue is being investigated. Thank you.
