After upgrading from a 1080 to a 3090 I cannot get premiere to play back, without massive stutter and lag.
SAS raid with 800MB/s Read and Write Speeds. (Same if played off ssd)
Intel I7 8700k
EVGA Nvidia RTX 3090
260.89 Studio Driver
Doesn't work with game ready driver either.
Same and I have an I9 processer and 64g of RAM
I pulled the 3090, and using the internal graphics, the playback is the same. I'm going to do a full clean install and test.
I did a complete fresh windows 10 install. Everything worked fine for 2 days using the Nvidia driver that was installed by default.
Started the computer today and installed Epic Unreal Engine Launcher and I can't edit any more.
Stuttery, lag, atudio is choppy and slow. Going to fresh install again.
Some of the gaming and specialized 3D "engines" install a host of things on the system that run in the background constantly, plus reset the GPU and OS graphics settings to their needs ... and control.
Even some of the "it's only a sound setup" things do this.
And they interfere with Premiere Pro's operations.
Out of curiousity, what do you use Unreal engine for?
Building out enviornments for Virutal Production utilizing greenscreen and LED walls. Like the Mandalorian but on a much smaller scale. I unistalled Epic Games Launcher and it didn't help, so attempting to re install.
This is my most powerful computer, so I prefer to use it for editing and virtual production. There's only so much desk space and I'm already running two KVMs, so I would prefer to avoid having to buy a dedicated machine for each task.
I would look at Kevin's comment about your GPU drivers. The driver you listed sounds very old - the 3090 probably didn't even exist when those drivers were out, and Premiere may require a driver well beyond that now anyway. You don't want to rely on Windows to tell you what driver to get. Go to Nvidia.com and get the latest studio drivers.
